Unisex Super Thermo T-Shirt Base Layer with Inlay

(2 customer reviews)


Exceptional warmth and moisture control in an extremely lightweight base layer. The ST T-shirt with inlay 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. The inlay on the should provides a smooth comfortable surface for pack straps to rest. Sizes: XXS – XXXXL. Color: navy.

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.”

    This is my second shirt from Brynje, but this one has the inlay on the shoulders which should help with backpacking. I am using them on my morning run to manage moisture and heat loss. Works great by keeping me drier and more comfortable. They really do what the specs say they do. Right now the weather is cold and damp on the east coast, but I will use them next summer in the heat as well. Great product.

    Fantastic shirt which does what it claims to do, regulates temperature, and helps keep you drier. You never feel sweaty, it’s very warm when worn under something, but you can easily cool off just by unzipping the outer layer. Love it! Does’t seem to get very smelly either, even after 2 days of xc skiing. The inlay makes it comfortable with a pack.
