"What Our Gearhead® Experts Are Saying:""I wore the Ridge Tech 1/2-Zip Top on a bouldering trip where the temps were hovering in the low 40s, and it was exactly what I needed. The waffle knit keeps you warm without feeling stifling, and the half-zip lets you dump heat fast between problems. The dropped shoulder seams made a noticeable difference when I had a pack on the approach.""Cold mornings at the boulders have a particular rhythm. You park, pull something warm over your base layer, and shuffle toward the first problem with hands wrapped around a thermos. The Marmot Ridge Tech 1/2-Zip Top fits that moment perfectly, soft and substantial against the chill, with a textured jacquard waffle knit that looks as good as it performs. Marmot built this one for the in-between hours when a shell is too much and a tee is nowhere near enough. The stretch blend of cotton, recycled polyester, and elastane moves through every reach, heel hook, and scramble without pulling or binding. Side panel construction and dropped shoulder seams keep the fit relaxed and friction-free, whether you are moving over rock or carrying a loaded pack to the next sector. Crack the half-zip when the sun breaks, and the sending temps arrive, stash a snack in the kangaroo pocket, and keep the zippered pocket close for the things you actually need to find again."
