Top 10 Thermal Underwear Manufacturers

The cold weather is coming, and the principle of layering turns from a fashion whim into a necessity. In the Russian expanses, this means that under a warm winter jacket and windproof pants, the body is best packed in an additional layer of thermal underwear. And if quarantine is introduced again, thermal underwear will serve as an excellent analogue of comfortable home clothes.

This season, thermal underwear was created by a wide variety of manufacturers, from inexpensive budget brands to lines for professional athletes. Here are popular thermal underwear brands whose products are available in Russia.

10. X-Bionix

This company can be called the most high-tech of all those participating in the rating without any exaggeration. If you want to know how exactly thermal underwear from X-Bionix works, then get ready to look at the search engine often - otherwise, you will not be able to figure out what this or that technical term means.

The company's founder, thanks to research in the field of thermoregulation and sweat wicking, was able to create truly "smart" sports underwear that not only effectively wicks away moisture and keeps you warm, but also has zonal compression - that is, it supports muscles and does not squeeze blood vessels.

The brand has lines for professional athletes. These are products that can not only wick away moisture, but also cool muscles in strategic places, increasing productivity. And there is thermal underwear made of wool, which keeps you warm during winter sports. And, what is important, all models from X-Bionix have an easily recognizable, spectacular and modern appearance.

9. Uniqlo

Inexpensive, accessible, but at the same time Japanese-quality and stylish brand Uniqlo launched a new line Heattech on the market a year ago. The collection is, of course, minimalistic (after all, it is Japan), but at the same time fashionable enough so that you won’t be afraid to show the edge of a T-shirt from under your office jacket.

According to the manufacturer, the ultra-warm Heattech knitwear is approximately two and a half times warmer than regular thermal underwear. The reason is the two-layer nature of the garment; while the outer layer is made of soft, pleasant to the touch cotton, the inner layer is woven from an innovative material.

The viscose in the fabric is responsible for absorbing moisture and generating heat, and the special weave of very fine fibers retains body heat and prevents tentacles of cold air from penetrating your collar.

There are three types of Heattech items:

  1. "regular" (thin but warm material is suitable for both the office and home),
  2. with fleece (about one and a half times warmer),
  3. super warm, in which you will be warm and cozy even in the most severe frost.

8. Terramar

This brand is young and early, which results in high technology - it was Terramar engineers and technologists who created two innovative materials.

  1. Thermasilk is made from natural silk, which is specially treated to retain body heat and serve perfectly as a bottom, body-hugging layer of thermal underwear. In addition, silk itself has moisture-wicking properties, which is very important for comfortable thermal underwear. And, of course, it is very elastic, so underwear made from such fabric does not restrict movement at all.
  2. And the second signature Terramar material, the Body-Sensors knitted thread, will help balance your body temperature both during rest and during active activities in the fresh and cold air.

7. Spyder

This thermal underwear is able to keep you warm even in the harsh winters of the Urals (provided that the second layer is fleece fabric). 51% from the fabric is Avra, which is made ... from recycled plastic bottles (melted, stretched into ultra-thin threads and woven with other materials).

The result is a fabric that dries quickly and is more elastic and soft than standard, inexpensive polyester underwear. The skin in Spyder underwear breathes, and the material wicks away moisture, so your muscles don't cool down between physical activities. The anatomical cut and elastic seams help the product fit your figure like a second skin. And the original print allows you to look fashionable.

6. Patagonia

One of the best features of the high-tech fabrics used to make Patagonian thermal underwear is that they work equally well on a snowy mountainside as they do at a bus stop.

Beyond keeping you warm, Patagonia's products have a host of other features, including HeiQ Fresh odor control and Power Grid seams that reduce friction.

One of the brand's special features is concern for the environment, so Patagonia fabrics often include recycled and biodegradable materials. But don't think that such fabrics will be short-lived - Patagonia is famous for the strict tests it subjects its products to. For example, the test with the telling name Killer Wash - when in 24 hours a thing "survives" as much as its counterpart in years of intensive wear in a humid climate.

5. The North Face

Thermal underwear from The North Face is specially designed for those who spend their time actively outside the home in winter.

That is why the brand’s products do not have side seams (to prevent chafing), and the T-shirts are supplied with a gusset (a rectangular wedge) under the armpit – so that nothing interferes with the swing of the arms in different directions and for maximum convenience.

Two years ago, the company began using an electrospinning membrane in production, when a very thin polyurethane nanocoating is applied to fabric (almost any fabric). Fabric treated in this way is extremely flexible, stretches in all directions, but at the same time maintains high vapor permeability. Experts believe that this technology is the future of sportswear.

And although, let's be honest, The North Face underwear looks very utilitarian, there is a special chic in this rough simplicity.

4. Marks & Spencer

Shopping at M&S is a win-win option, as our compatriots of both sexes have been able to see since the opening of stores of this brand in Russia. These are relatively inexpensive, durable, long-lasting clothes with a solid, without risky frills, design, and their thermal underwear is the same.

The level of warmth will be average (not comparable to specialized sports brands), but the variety of styles (from sleeveless T-shirts to seamless thermal shorts) and their elegance will allow you to wear such underwear not only in the mountains and forests, but also to work in the office.

3. Hanro

Trendy materials and eco-friendliness are all well and good, but nothing beats the good old cashmere and silk combination offered by one of the best thermal underwear brands.

Thin elastic fabric that can be worn directly on the bare skin - no bites from coarse wool. This thermal underwear will make an excellent pair with a jacket or jumper in the office, even with the strictest dress code.

2. Duofold

The American brand Duofold has three lines of thermal underwear. Originals is the most “everyday” — it is two-layer, the bottom is cotton, the top is a mixture of cotton and nylon. It is perfect for urban conditions, everyday wear from indoors to outdoors and back. The underwear will withstand even high humidity — it will effectively remove body fumes, but at the same time the surface of the body will not cool down, and the person will be dry and comfortable. Polyester cuffs that do not let cold air in and elastic soft seams that will not rub the skin will help to retain heat.

The second line – Thermals – already consists of 60% cotton and 40% polyester and is designed for the mild Central European winter.

And the third, Varitherm, looks like it could even withstand a trip to the North Pole – it’s that warm.

1. Alloy

One of the best domestic manufacturers of thermal underwear produces all possible types of clothing.

  • There is also a lightweight, moisture-wicking version that fits close to the body (it can be used as the main clothing when doing sports - running or cycling).
  • There is also a thicker, more versatile one that can be worn on its own or in winter as a middle layer between thin moisture-wicking underwear and a warm jacket. This way, the body will be dry, and at the same time, there is an additional layer of protection from the bites of frosty air.
  • And for fans of active sports or winter hunting/fishing, there is the warmest option, which is worn either alone or in combination with the first.
