The men's fleece with zip Outdoor Research Vigor Grid Half Zip is a premium technical midlayer specially designed for high-intensity activities on colder days, such as ski touring, mountain running, or winter hiking. The innovative grid interior structure creates air pockets that effectively increase thermal insulation while allowing rapid moisture wicking away from the body.

The integrated advanced ActiveTemp™ technology acts as intelligent thermoregulation that actively responds to your exertion – effectively venting excess heat during movement while trapping valuable warmth at rest. The garment is thoughtfully designed, with flatlock seam construction preventing uncomfortable chafing when wearing a backpack.

The product is crafted from sustainably minded materials, specifically 94% polyester and 6% elastane, backed by bluesign® certification. For added functionality in the field, integrated thumb holes at the cuffs keep the sleeves in place, and a handy zippered chest pocket provides secure storage for small essentials.
