  • Types of Thermal Underwear

    Posted on September 9, 2014 by olinselot

    Maybe you're an avid extreme winter mountain trekker or you simply get the chills while working in the cool office, you operate heavy mining equipment year round or you work for the US Coast Guard. Either way, thermal long underwear, also known as base layer or long johns, may be just what you need to stay warm and comfortable. The type you choose will depend on your activity level, your budget, and the temperature.

    There are many types of thermal underwear but our customers usually choose one of these top three.

    Merino Wool

    Merino Wool thermal underwear is our warmest underwear. It doesn't itch or smell like regular wool can. It is very soft and comfortable against your skin. It wicks moisture away from your skin when you get wet. It also maintains its thermal properties, keeping you warm, even when it is wet. Best of all, it is made from natural materials that are environmentally sustainable. Merino sheep need a haircut once in a while just like you do - no harm done.


    polypropylene thermal underwear

    Polypropylene is a popular material for thermal underwear because of its affordability. It is less expensive than many other options, but has many of the same benefits. Polypropylene will stay warm when it gets wet. It is durable and will last a long time. It dries very fast compared to other materials and it also wicks moisture away from the skin.

    100% Cotton

    100% cotton thermal underwear

    100% Cotton thermal underwear and long johns are hands down some of the most comfortable, warm underwear you can get. It is very affordable, comes in a variety of colors and styles, and is made from renewable and natural fibers. The comfort and feel of cotton is hard to beat.

  • Long Underwear from Long Ago

    Posted on December 9, 2013 by olinselot

    Primitive Layering
    Around the year 3300 BC, a primitive man now known as Otzi, or the "Iceman", lived among the mountains near Italy. In 1991 the preserved body of Otzi was discovered mostly frozen in a high ice form. What was most exciting was that most of his clothing and survival gear were still intact.

    OtziOtzi wore a fur hat made of bear hide, a cloak of woven grass reeds, a belt of calf leather, bear skin shoes, and most importantly - long underwear made of goat skin wool. Long before recorded history, early humans lived and thrived based upon their ability to endure the environment. The tools they created and and materials they formed into their clothing were a serious matter.

    One of the most enlightening parts of Otzi's attire was his long underwear. Made from goat skin, the woolen hide provided him insulation from the snow and wind. In modern times we have the advantage of high performance synthetic thermals and time tested merino wool long underwear. We can learn from the ancient wisdom of primitive man and combine it with modern technical advancements.

    Premium PerformancePremium Performance long underwear has been crafted from a blend of 85% polyester and 15% spandex. Designed to cut through the cold and wind, Premium Performance long underwear provides maximum comfort and mobility. It also benefits from antimicrobial odor control; a benefit that probably would have been greatly appreciated by Otzi's friends.

    If you are more keen on natural and renewable materials, then premium merino wool long underwear is for you. If Otzi had premium grade merino wool thermals he would have been able to stay dry, keep warm, move faster, and smell better. Ancient wisdom still applies when you are venturing into the outdoors. Learn from the lessons of the past and clothe yourselves to thrive.

  • Lightweight Thermal Underwear

    Posted on May 20, 2013 by olinselot

    Changing SeasonsTrying to decide which type of thermal underwear is best often leads to thoughts about deep winter blizzards and hypothermia. Spring comes along and you stuff your base layers in the same storage bin as your heavy coat and snow gloves. When it comes to your spring and summer recreation, It's time to change your thinking about what thermal underwear is and when to use it.

    Consider almost every other fuzzy animal that lives and dies based on its fur coat. When warm weather comes they don't shed every strand of hair and bask in the warm sun with no fur at all. Instead they shed their heavy winter coat and establish a lighter layer of fur to protect them from moisture, wind chill, and even the burning sun. So why do we humans suddenly ditch our common sense and put on a thin layer of non-insulating material as if that is the best option?

    Silk Weight ThermalThere are multiple lightweight or silk weight options that will expand your options beyond the cold temperatures of winter. The Duofold Varitherm Silk Weight thermal is an excellent example. It has a single layer, dri-release, poly/cotton blend that is designed to be worn during cool or warm weather. This makes it a realistic option 365 days per year. Silk weight thermals come in a variety of options including long sleeve, short sleeve, v-neck, tops and bottoms to suit your preference.

    Many people want the insulating properties of thermal underwear without sacrificing the comfort they know and love from the feel of cotton. You don't have to shy away from cotton based thermal underwear under the assumption that it doesn't have the moisture wicking properties of wool. Camo Cotton Poly ThermalThere are many cotton/polyester blends that will dry much faster than 100% cotton fabric. The cotton/poly blend also provides a wider variety of colors and styles including white, blue, black, red, camo patterns and more. Most of all you'll notice the considerable price difference in sizes for adults and even children. Many of the thermal underwear options on Outersports have been reduced in price due to the change in season. Don't miss out on a great opportunity to get the thermal base layers you need for any season or occasion.

  • Polypropylene Thermal Underwear Used By The U.S. Navy

    Posted on October 15, 2012 by

    100% Polypropylene - History and Uses

    100% Polypropylene underwear has been around for quite some time. Polypropylene was developed in the 1950's. When it was realized that polypro absorbed very little water and retained heat extremely well, it was spun into a thread for use in thermal underwear. Polypropylene has been a very popular performance thermal ever since. It has become a staple for many outdoor industries where the user is exposed to cold wet climates. Cruise liners traveling through the Arctic or Antarctic request that travelers wear polypropylene thermal underwear as a base layer because of its' ability to retain heat better than any other fabric.

    Polypropylene is also very light weight. Available in a thick fleece knit, 100% polypropylene thermal underwear only weighs a fraction of what cotton thermals with the same temperature rating would weigh. One unique and highly desirable feature of 100% polypropylene is the ability to retain heat even when it gets wet. I have a friend that has run river rafting tours on the Colorado River where it winds through The Grand Canyon. One problem river guides have faced over the years is hypothermia due to constant exposure to the cold river water. My friend says he wears polypropylene thermal underwear as a base layer because it is excellent at keeping you warm in cold water. Instead of the cold water sucking the heat away from  your body, the polypropylene insulates you and keeps your body's natural warmth next to your skin.

    Polypropylene Thermal Underwear Mandated for Navy and Coast Guard

    This leads us to the title of this article. All of the properties I've mentioned so far make 100% polypropylene ideal for the U.S. Navy and the U.S. Coast Guard. Dive and rescue teams that will be entering the cold ocean waters are required to wear a base layer of 100% polypropylene underwear underneath their dry suits. OuterSports has a contract with the U.S. Government to sell polypropylene thermal underwear in bulk to The U.S. Armed Forces. The U.S. Coast Guard and U.S. Navy typically has Outersports supply them with the high quality Coldpruf 100% Polypropylene Thermals. There are many different brands you'll find polypro thermals in. But the Coldpruf brand has a much softer hand so it feels great worn next to your skin. OuterSports also carries 100% polypropylene thermal underwear in a thick two layer fleece. This is used as part of the Extreme Cold Weather Clothing System or ECWCS by all of the U.S. Armed forces. Like its' name infers, the thick fleece polypro part of ECWCS is great for extreme cold. The first rule of thermal insulation is that the more air a fabric is able to trap the better it will insulate and the warmer you will be. Polypropylene in fleece form traps more air while the fabric itself retains more body heat than any other fabric. I love to wear the fleece polypropylene thermals when I go out snowmobiling on colder days so I don't have to worry about getting cold.

  • Polypropylene Vs. Polyester

    Posted on October 2, 2006 by Justin

    I've had many people ask me what the difference is between polypropylene fabric and polyester fabric used to make thermal underwear. In this post, I'll point out ony the factors that I think are the most relevant.

    First of all, polypropylene and polyester are synthetic materials. They are both polymers, which is essentially plastic. As a result their colors won't fade or bleed when washed because the colors are built into the material. Polypropylene however, is more hydrophobic than polyester meaning that it does not absorb as much water. Since the water cannot be absorbed into the fabric, the water(or sweat) has a tendancy to spread evenly throughout the garment which in turn helps the water to evaporate much quicker than a fabric that absorbs and retains the water. As a quick example, if you cup your hand and put some water in it and continue to hold the water in your hand with your hand still in a cup shape, the water will take a very long time to dry. But, if you uncup your hand and use your other hand to spread the water evenly all over both of your hands, the water will dry in less than 1 tenth of the time.

    So, having explained this, polypropylene will dry much faster than polyester. Polypropylene has a much lower melting point than polyester so you will want to avoid washing polypro in hot water or drying it. For this reason, polyester materials are much easier to care for than polypropylene. Polyester is also more UV resistant than polypro. If you wear polypropylene as an outer layer exposed to the sun, eventually the polypropylene fabric will break down and the color will fade. Polypropylene has a lower heat transfer rate which means that thermal underwear made from polypro will retain more heat than polyester.

    So really, whether one fabric is better than the other really depends on what it will be used for. If you just need a fabric to wear next to your skin that will dry very quickly and thus keep you skin dry, then polypropylene is probably what you want. If you want just a good all around fabric that also dries quickly, but is very easy to launder and care for, then polyester is probably your best bet.

  • Snowmobiling - What Should I Wear?

    Posted on May 25, 2006 by Outersports

    The first time I went snowmobiling, I wore a nice thick layer of thermal underwear under some cotton sweat pants and a hoodie sweatshirt. It was pretty cold outside and I had heard that, while snowmobiling, the wind chill factor can make things even frostier. I had also purchased what I thought was the perfect snowmobile suit. It was one piece suit that zipped up the front and was about an inch thick with insulation. I didn't have any special snow boots so I just wore my hiking boots with some extra thick socks. All set right? Well, not everything worked out for me as I had planned.

    When we hit the trail, I was sure warm. In fact, I wore the one piece suit along for the ride to the trail so by the time I got out of the truck, I was beginning to sweat a little. We hadn't snowmobiled long before I found myself stuck in a deep snowbank. I didn't think it was a big deal until I started trying to dig the 500+ lb. machine out. After some time and with a lot of help from my friend I found myself unstuck and sitting on my snowmobile with a cloud of steam rising from my head. I was now hot, sweaty, and exhausted. Also, snow had gotten packed all down into my boots so my feet were now wet. Without drawing this experience out too long, I did have a blast snowmobiling. But, in the end, my rear was soaked, my feet were frozen, and all of that warm thermal underwear I had put on was completely wet with sweat making my entire body chilled to the bone.

    So, here are some tips to avoid these pitfalls. First, wear layers that are easy to remove. Many snowmobile pants have full zippers down the legs so that you can remove them easily. Second, do not wear anything cotton. Wear polypropylene underwear or some other synthetic quick drying underwear so that after you're done sweating from digging your machine out, you dry out quickly. Third, your outer layer should be waterproof and breathable. If it isn't, you rear will be soggy and cold. Lastly, you will want to wear boots that have waterproof soles. You will also want to make sure they come up to at least mid calf so that you can pull your pants down over them. While you are sitting on a snowmobile, your pant legs will ride up exposing your calves to the cold.

    A few other helpful tips include wearing a helmet with a face shield. If you don't have a face shield, you will want to wear a windstopper balaclava or something similar that will completely block the wind from your face. The cold combined with the wind from riding can really freeze your skin.

  • Canoeing - What should I wear

    Posted on May 25, 2006 by Justin

    Getting ready for a relaxing canoe trip? Follow these general guidelines for a fun and save canoe trip. As with any outdoor activity, you will need to consider how active you will be during the activity. You will also need to assess the physical elements such as: will you be canoeing in rapids or on a calm lake, is rain expected or is sunshine in the forecast, is the weather going to be warm or cold? All of these factors will determine what you will want to wear while paddling your canoe. Also, because you will be on the water, there is always a chance of an unexpected dip.

    Warm Canoeing:
    One option to consider is the beach look, including a swimming suit and some sunblock. Not much more is needed. If you prefer not to dress down that much, you are pretty safe wearing some lightweight shorts or long pants and a t-shirt. Don't wear cotton as is will stay wet longer. Even on a nice sunny day, cotton pants and shirts take more than twice as long to dry than synthetic fabrics. Shorts or long pants made of lightweight nylon are great for canoeing. If water does happen to splash onto them, they will be dry again within minutes. Polyester or polypropylene t-shirts are great for water related activities. Helly Hanson makes a wide variety of polypropylene t-shirts that will dry faster than any other material you will find. Now, as for shoes, you might want to consider wearing lightweight sandals that won't slip off. There are many options in the footwear area so choose something you would be most comfortable with. In warm weather, sandals are great because they let your feet breathe and they allow your feet to dry out quickly if you happen to get them wet. Shoes are ok to wear, but if you get them wet, your feet will be pretty soggy by the end of the trip.

    Cold Weather Canoeing:
    In cold weather conditions, you need to be prepared for the worst. White water or fast flowing water means cold water. Even if you aren't planning on falling in, there are still plenty of chances of getting wet. When I was in high school, my friends and I decided to take dates canoeing down the last stretch of the Provo River in Utah in early spring. We had no intentions of getting wet and we therefore did not prepare for it. Well, about halfway down the stretch, there was a bend in the river that caused the water to flow rapidly to one side of the river. To make a long story short, 4 of the 5 canoes tipped over spilling us into the cold winter runoff water. We managed to get all of the canoes back upright and continued our journey. If our trip had been much longer than it was, we would all have suffered from hypothermia. Either way, our canoe adventure didn't turn out as fun as we had planned.

    So, always plan to get wet. Go with the layering system. First layer-thin, lightweight, synthetic fabric. Second Layer-synthetic fleece insulating fabric. Third Outer Layer- Windproof and waterproof fabric. Canoe and kayak specialty stores sell products for the outer layer specific to paddle sports. They will have seals around the collar and the cuffs to prevent water from entering. Unless you are doing some aggressive canoeing, you can probably just use your waterproof ski parka or even a rain parka. This layering system will allow you to adjust your dress to control your comfort range. Using synthetic fabrics will keep you warm even when you do get wet. For footwear, you can get neoprene socks and shoes that work really well for cold water canoeing. A thin polypropylene sock liner will add some extra warmth if you need. Boots made for wet suits that have vulcanized soles are probably your best bet if you are planning on a long trip. For your hands, you will want some neoprene gloves. Thin polypropylene glove liners can be worn underneath them for added warmth.
