Outdoor Research Deviator Fleece Half Zip | Built for Breathability and Movement

When You’re Running Hot in Cold Weather
The Outdoor Research Deviator Fleece Half Zip is a high-performance hybrid midlayer designed for fast-paced missions in cool climates. Whether you’re trail running, splitboarding, or hustling uphill in full kit, this fleece keeps you warm without overheating.

Blending moisture-wicking polyester in the core with bluesign®-approved stretch panels in the sleeves and underarms, the Deviator brings elite-level breathability, movement, and thermoregulation. The VerticalX™ Octa insulation is 50% lighter than standard poly fill and built to dump heat fast- no liner needed. Plus, the 13” front zip lets you vent on the fly, and thumbholes add warmth and coverage when the wind kicks up.

Why We Love It

This isn’t your grandpa’s fleece. The Deviator is tuned for the tempo, giving you warmth where you need it and flex where you don’t. Wear it on its own or layer it under a shell- it performs like a technical midlayer, not a fashion hoodie.
