The fabric: you stay warm without soaking through
Most cheap fleeces trap sweat on a climb, then chill you when you stop. Ours is Polartec Power Grid, the grid fleece Polartec says the US Army’s ECWCS Gen III Level II layer, nicknamed “the waffle”, is made from.
Raised squares hold warmth, the channels between them let sweat and heat out. You climb, you stay dry, you stay warm.
