Peak Performance Felpa in pile Trail Polartec Power Grid donna - verde

When the trail turns chilly and the wind picks up, a standard fleece can leave you damp and overheated on the climbs, then chilled on the descents. The Peak Performance Women's Trail Polartec Power Grid Crew solves this with a grid-backed Polartec fabric that traps warmth while letting excess heat and moisture escape. Built for active days in the mountains, this mid-layer keeps your core temperature steady from trailhead to summit.

Who is it for

This crew is made for women who hike, trail run, ski tour, or simply need a reliable layer for cool-weather outdoor adventures. Its regular fit and 4-way stretch allow unrestricted movement, while the flatlock seams prevent chafing under a pack or harness. Whether worn as a standalone on brisk mornings or as a mid-layer under a shell, it adapts to changing conditions.

Tips

Pair this fleece with a lightweight baselayer for cold starts, and add a waterproof shell when the weather turns. The grid interior creates air channels that speed up drying, so you can wash it in a sink on multi-day trips and expect it to be ready by morning. For a closer fit, consider sizing down; for layering over a thicker baselayer, your usual size should work.
