Love the zipper pocket
It's the perfect size for my phone, keys, id, and chapstick. It’s tight so it keeps things from bouncing while running which is perfect!

Cold weather running comfort. The design of our streamlined Mercury Qtr-Zip is based on those four words. A refined raglan sleeve allows for total freedom of movement while integrated thumb slits and a cadet collar add extra protection. A single zip chest pocket keeps storage simple. The true stand-out feature of this modern update on the classic mid-layer is the fabric, which is both high-performing and exceptionally soft and cozy — thanks to light peaching on both sides that provides warmth without added weight. This is the new go-to when the mercury drops.
