Unisex Super Thermo T-Shirt Base Layer

(3 customer reviews)


Exceptional warmth and moisture control in an extremely lightweight base layer. The ST T-shirt can be worn all four seasons as the mesh design provides warmth when the second layer closes the air cells yet will cool when the second layer is opened to allow air to pass over the skin. Since the polypropylene yarn absorbs little moisture you will always be dry and comfortable. ST T-shirts are the most versatile garments you can own. Size: Unisex XXS – XXXL. Color: White, Black.

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.”

    The last mesh shirt I had, many yers ago, was made of wool. This one works well in humid or wet conditions and is more comfortable next to the skin. I use mine as the first layer under my dry suit (diving). Agree with the comment concerning the logo.

    Great except for logo on neck

  3. Thomas Contolini (verified owner)

    Well made and very light. Does help with moisture management which is always a problem with outdoor activities in winter or summer. I had a mesh tee shirt many years ago (made by Synergy Works I think). That shirt is long gone now, but I am glad that I was able to stumble upon the Brynje shirt. Thanks for a quality item.
