Made for superior breathability, wicking, and warmth with minimal weight using Polartec® Power Grid™ fleece, our highly adaptable midlayer provides comfort through all four seasons.

We’re always pushing to create the most comfortable, lightweight and adaptable layers, because we love exploring our home range year-round—and that means preparing for fast-changing conditions and a range of environments. That’s why this low-profile, wicking fleece is never leaving our packs. Polartec® Power Grid™ delivers best-in-class warmth with less volume due to the raised grid design that traps heat when it's needed and lets it out when it's not. Stretch integrated into the fabric moves through your full range of motion and fast moisture wicking keeps you dry and comfortable. Flatlock seams ensure smooth layering while thumbholes keep sleeves in place. The concealed zipper pocket on the lower hem stashes small essentials.
