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.”

    I like using these mesh boxers as a base layer for heavy winter activities. They are fairly comfortable under thermal leggings.
