The Kelvin Aerolite Vest by SITKA Gear is a highly versatile piece that works well in almost any hunting system. The vest slips comfortably under a shell whenever you need an extra shot of warmth or as an outer layer during mid-season hunts. The Synthetic PrimaLoft® Gold Insulation with Cross Core™ technology replicates the aesthetics and performance of down insulation, but with warm-when-wet performance. The Kelvin Aerolite Vest also features DWR (Durable Water Repellent) Technology that is designed to prevent your system from wetting out, keeping you dry and comfortable no matter where your hunt takes you.
