Brynje Heritage - The Original String Vest 

The Brynje Original String Vest is a pioneering piece of thermal wear technology made famous by Tenzing and Hillary during their ascent to Mt. Everest in 1953.  

The string vest and other cotton mesh undergarments in our Heritage collection are suitable for everyday use. 

For high-intensity activity, we recommend our other baselayers with enhanced wicking capacity, such as Super Thermo and Wool Thermo mesh.
