Built for high-output activity in cool and cold conditions

The Outdoor Research Men’s Vigor Grid Fleece Bottom delivers lightweight warmth, excellent breathability, and efficient moisture management in a low-profile technical base layer.

The Vigor features a waffle-grid fleece interior that traps warm air while creating channels that allow excess heat and moisture to escape. This construction provides an excellent balance of insulation and ventilation, making it especially effective during active cold-weather use.

Outdoor Research’s ActiveTemp™ thermoregulating technology helps manage body temperature as activity levels change, while the moisture-wicking, quick-drying fabric helps keep the wearer comfortable during extended movement.

The 94% polyester / 6% spandex construction provides movement-mirroring stretch for unrestricted mobility, while the trim fit allows the bottoms to layer comfortably beneath combat pants, technical shells, or insulated outerwear without unnecessary bulk.

Flat-seam construction reduces pressure points and chafing during extended wear, while an internal elastic waistband provides a secure and comfortable fit.

A bonded Ferrosi® zippered pocket at the right hip provides secure storage for small essentials while maintaining the low-profile design.

Lightweight, breathable, and easy to layer, the Vigor Grid Fleece Bottom is an excellent foundation for an active cold-weather clothing system.
