WHY THIS JACKET WAS MADE

The best thing about synthetic insulation is that it stays warm even in extreme, wet conditions. Until now, that reliability has come at the cost of bulkier and heavier products. The Kelvin Aerolite Jacket harnesses the insulating properties of trapped air to create synthetic insulation that replicates the low-bulk, highly compressible characteristics of down, but with warm-when-wet performance. We designed this go-to, versatile layer to keep you warm when you need it, yet disappear in your pack when you don’t.

 

Sitka - Jacket - Kelvin AeroLite Jacket - Coyote

In a sea of outdoor specialization, having versatile gear as well is a strength. This lightweight, compressible jacket maximizes warmth while minimizing bulk. Use it for everything from backcountry hunts and off-season scouting trips to everyday life; it slips comfortably under a shell whenever you need an extra shot of warmth. Synthetic PrimaLoft® Gold Insulation with Cross Core™ technology replicates the aesthetics and performance of down insulation, but with warm-when-wet performance.
