***Outdoor Research's Trim Fit is designed to contour the body for a streamlined, athletic fit***
The Outdoor Research Men’s Deviator Fleece Half Zip is a high-performance midlayer designed for active pursuits where breathability and lightweight insulation are critical. Built with VerticalX™ Octa insulation and hybrid-mapped construction, it provides targeted warmth at the core while allowing excess heat to escape through stretch panels in high-output zones. The result is efficient temperature regulation during movement, making it ideal for hiking, hunting, and backcountry travel. A deep front zipper allows quick ventilation, while the athletic fit and stretch design ensure unrestricted mobility and all-day comfort in changing conditions.
