Brynje Classic Original mesh sticks to the core of the Brynje philosophy on keeping people “warm, dry, strong and happy”......except you can now have it in Merino!
It has been designed to meet the high performance needs of outdoor enthusiasts and the stringent requirements of some of the world’s top military soldiers, including Norwegian Special forces.
The concept is incredibly simply, and is based on the most efficient material you can use......air! Nothing breathes, insulates or dries like air! The Classic Original mesh garments are knitted double-sided using 80% Merino wool and 20% Polyamid, giving a super soft feel with a nice close fit.
The secret to the high performance of Brynje mesh clothing is that it draws excess moisture away from the skin while maintaining a warm regulated cushion of air next to the body. With conventional solid knit underwear the perspiration cannot escape quickly enough through the fabric so the fabric next to your skin becomes sodden and you quickly become cold. With the Brynje Classic Original the air pockets in between the mesh allow the body to “breathe” more easily and naturally, while maintaining the trapped air for insulation. This allows for superb body temperature regulation in hot to cold climates, and is the reason it has become popular with cyclist the world over, from the amateur to elite.
This key factor of super efficient moisture transportation coupled with the insulating properties of the trapped air will keep you surprisingly warm and dry during the most demanding activities.
