I have no idea how much I sweated out on the last climb up to the Stoneman checkpoint, but I know that crossing the Demuth passage and the single track descent that follows will be worth the effort. More than 13, feet of vertical ascent in two days and I only needed a minimum change of clothing thanks to this great base layer. That's what I call clever functional wear.
