Finally an alpine touring liner that doesn't suck! The Zipfit GFT Liners work to elevate your experience on both the uphill as well as the downhill. Designed with a comfortable (and warm!) neoprene interior that efficiently manages sweat and prevents blisters, plus a toe box insulated with Thinsulate™ and merino wool, the GFT doesn't compromise on those frigid 3am starts, nor those balmy spring volcano missions. With a flexible rear panel to allow for forward flex and front articulation points for full range of motion, and a unique system that allows more cork to be added to both the tongue and/or ankle pockets, the Zipfit GFT Liners are essential if you want to bag peaks AND actually enjoy the ski back down from the top.
