Peak Performance Men's M Trail Polartec Power Grid Crew Mid-Layer Fleece Brown XL

Most mid-layer fleeces force a trade-off: warmth for breathability, or stretch for durability. The M Trail Polartec Power Grid Crew breaks that compromise. Its patented grid construction traps warm air in the fleece's loft while channels between the grid move moisture away from your skin, keeping you dry on steep ascents and warm on windy ridges. Made from 93% recycled polyester and 7% elastane, this crew delivers four-way stretch that moves with every reach, pole plant, or scramble.

Highlights

• Polartec Power Grid fabric: lightweight warmth with high breathability
• 93% recycled polyester, 7% elastane: sustainable and stretchy
• Excellent moisture-wicking and quick-drying properties
• Four-way stretch for unrestricted movement
• Flatlock seams reduce irritation during activity
• Regular fit with crew neck for easy layering

In daily use

On early morning trail runs, the Power Grid fleece manages sweat so efficiently that you stay comfortable even when the pace picks up. The grid pattern creates channels that move moisture away from your skin while trapping warm air in the fleece's loft. When the wind picks up, pull on a shell and the crew neck disappears beneath it without bulk. For ski touring or winter hiking, this mid-layer provides just enough insulation without overheating, and the four-way stretch lets you move freely through technical terrain.
