Push your performance even further. The grid design was developed to reduce fabric weight while increasing warmth and compressibility. The grid construction is made by channels between touch points that helps both wicking efficiency and breathability. Thin fleecy grid on the inside pulls moisture from your skin and diffuses it to the outside. This avoids using chemical wicking agents that fade away with time. The open air channels also allow air to circulate, increasing thermal warmth and mechanical wicking capabilities. The outer surface is smooth. It spreads moisture out to a wider surface area for faster evaporation. The Polarstretch materials are hard-wearing, pliable and flexible in all directions as well as lightweight and easy to maintain. Polarstretch fabrics works best under a wind blocking layers. We suggest to use Polarstretch fabrics as a mid layer for intensive activities in cold conditions.
