Description

Brynje original Super Thermo (ST) mesh is made from 100% Schoeller® Polycolon® synthetic yarn, knitted into a 3/8″ open weave mesh that provides 4 to 6 times the insulating power of any solid knit by weight. The polypropylene yarn absorbs virtually no moisture while the mesh design allows perspiration to pass through the garment in vapor form. Nothing wet against the skin!

Polypropylene also has a very high strength to weight ratio providing super light garments designed to withstand years of extreme use. Brynje Super Thermo base layers have been used extensively in expedition work and are worn by Special Forces troops across the globe. Brynje ST garments are not just ideal for high intensity, cold weather activities. Because of the thermostatic qualities of the mesh, these base layer garments are exceptional for warm weather use as well. “Making the case for synthetic mesh base layers.”

    They are my new favorite base layer.

  2. Jacob (verified owner)

    I’m 5’11” and 230lbs muscular but still fat. Perfect fit

  3. Marjorie B. (verified owner)

    Great

  4. Jackson Hogan (verified owner)

    Great fit, comfortable, keeps me insulated and vented without having to use my thicker winter jackets. Now I just use my windbreaker shell jacket with a long sleeve shirt and some regular stretch hiking pants and it keeps me just as warm without as much bulk. No more sweaty base layers getting cold from windchill coming through your shell jacket and pants. The best way to utilize the leidenfrost effect for your base layer.

  5. Ian (verified owner)

    Awesome base layer for stop and go activities in subzero weather. A big help with moisture management if you do your part with ventilation and common sense.

  6. Benjamin Greenberg (verified owner)

    I like it

  7. Anonymous (verified owner)

    Very effective. Just wish they weren’t as long.

  8. Richard (verified owner)

    I’m 5’-7” 180 pounds and the large pants fit me fine. They performed exactly as they were supposed to.

    Excellent quality

  12. Darin (verified owner)

    Great product – have used it multiple times now first in the Sierras during winter and 10°F weather backpacking and then in Minnesota and 0°F weather pulling a sled across ice and then backpacking. The thing that blew me away was when I accidentally dropped an ice chisel through the ice and had to run a few miles to get a new one and then run back with a 30 pound ice chisel in my hand and was almost completely dry when I got back. Normally I would’ve had the chills gotten really cold afterwards but with these on felt perfectly fine. amazing product!

    Warm

  14. Randall (verified owner)

    A great product and above average customer service!

  15. Anonymous (verified owner)

    This is the best base layer I’ve ever had! Warms when it needs to, cools when it needs to. I’ve taken to just wearing them around the house. Could be a little tighter in back for those of us with smaller booties, but overall fantastic.

  16. Arthur Viens (verified owner)

    A must have for running, skiing, hiking, and fishing. This keeps your skin dry and prevents evaporative cooling when your skin stays wet from building up body heat from any endurance activity.

  17. Donald (verified owner)

    As a member of the U.S. military, these should be a standard issue base layer. Absolutely incredible performance. I will be ordering from your company again.

  18. Anonymous (verified owner)

    Great base layer

  19. Olivia Morgan (verified owner)

    great product!

  20. MICHAEL (verified owner)

    great product!

  21. Andrew G (verified owner)

    Great product, seems to work almost as well as the top. My biggest complaint is that the knee pads don’t line up with my knees, they are always sitting on my shins and just the edge touches the bottom of my knee. My second complaint is that the material that covers the knees, crotch and rear end is just like cotton. It doesn’t vent well and stays wet, leaving those areas clammy and uncomfortable, especially when you’re wearing multiple layers in the cold.

  22. Verified Buyer (verified owner)

    Excellent product! very warm and seems to be well constructed. More importantly, customer service was off the charts. I highly recommend Brynje USA.

  23. Rob S. (verified owner)

    I had some issues/questions with sizing and was given top-notch help that guided me to the right decision!

  24. Mark S. (verified owner)

    Perfect.

  25. Christopher (verified owner)

    Don’t hesitate to purchase these base layers if you are considering them. I also purchased the top without the inlays. It’s amazing how these ST tops and bottoms are like a magic suit that enhances all other gear used with them. My only regret… that I didn’t know about these 14,000 miles of hiking and mountaineering ago.

  26. Jim Pace (verified owner)

    These bottoms match my several year old top that still looks and works like new. Consider this an expedition quality item.

  29. K.Driver (verified owner)

    Very good quality, light and very soft. The fit is true to size.
    I’m 5’9 180lbs, 32 size jeans, 34 size dress pants, not fat, got a medium, and fits perfectly. The netting has some stretch.
    Obviously this works perfectly to evacuate sweat.

  30. Jared Suzuki (verified owner)

    Excellent quality! Light and very comfortable. A bit hard to decipher the sizing instructions but mine fit fine. Highly recommended

All sizes are averages and approximate. Your size may vary depending based on your body shape and the model.

Mesh base layers are generally quite stretchy in all directions and are cut long. As the girth increases the length will decrease

Generally the Women’s sizes will be one size smaller than Unisex. I.E. a Unisex SM is equivalent to a Women’s MD.

Merino wool can be worn multiple time between washings which will prolong the garment life and protect the environment. The synthetic fibers like Schoeller® Polycolon can be machine washed and hung to dry.

Hand wash or machine wash on gentle cycle with cool water (not to exceed 85°F).

Line dry. Do not tumble dry.

Do not use bleach.

Do not use fabric softener.
