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.”

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.
Laundry Instructions
Wool is a natural fiber which does not to be laundered regularly. A global wardrobe survey in 2015 by AC Nielsen confirmed that wool garments have a longer life than cotton – as much as 50% longer. 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.
Do not dry clean.

I hate to do this, but you’d like a candid comment, I’m sure. I ordered 2 pair of xxx and receive 1 xxx, 1 xx.
Samuel (verified owner) –
Incredible! Used it for six weeks of the Marine Corps’ toughest cold weather mountain training in the high Sierras and could not be more pleased with its performance. Kept me consistently warm and dry as I transitioned from sweating it out on long movements under heavy load before settling into camp for nights where the temps dropped below zero—wicking abilities are truly incredible. Customer service also unparalleled.

I’m 5’3’ and 160 lbs female. I ordered a large and they fit perfectly around my waist and hips/thighs. They were a little on the long side but that didn’t pose much of a problem. I was easily able to put on tight-ish jeans and leggings over them without a problem.
I slept in these at 28* with a 10* down quilt and was snug as a bug.
At 4.8oz for a large I would highly recommend these for those wanting to cut oz and still be warm!
