Sitka Gear Kelvin Light Vest Open Country

Having drank from the same cup as the Kelvin Jacket, the Kelvin Vest is a layering solution with a number of applications. When the temperature starts to plummet, and you need a lightweight, packable, insulated vest, the Kelvin is it.

Lightweight and packable, the Kelvin Lite Vest heats up your core without causing a meltdown. Built with 80 g/m2 PrimaLoft® Silver Hi Loft insulation, it serves admirably as both an insulating mid-layer and a core-hugging outer. Early in the season, throw it on to keep warm during periods of inactivity, and when the cold bears down, wear it to cover country without overheating.

The tightly woven polyester face packs down small, while durably locking out drafts to seal in a well-regulated microclimate around your core. Stretch-woven side panels make for an athletic fit that moves with you. Zippered hand pockets keep your hands warm, and a single zippered chest pocket secures your necessities.
