In a world full of specialized gear, versatility is key—and the Sitka Kelvin Aerolite Vest embodies that principle. This lightweight, compressible vest is designed to maximize warmth while minimizing bulk, making it an essential piece for everything from backcountry hunts and off-season scouting trips to your everyday adventures. Slip it under a shell for an extra layer of warmth whenever needed.

Key Features:

• Synthetic PrimaLoft® Gold Insulation with Cross Core™ Technology: Mimics the warmth and compressibility of down, but with superior performance in wet conditions.
• Lightweight Design: Weighing just 9.6 oz, this vest provides warmth without adding unnecessary bulk.
• Advanced Insulation: 35% recycled insulation infused with silica aerogel—a nearly weightless material composed of over 95% air, offering enhanced thermal insulation.
• Durable Construction: Features a 20-denier polyester face with a durable water repellent (DWR) finish and a 20-denier polyester backer to resist precipitation and prevent the fabric from wetting out.
• Convenient Storage: A deep, zippered chest pocket keeps your valuables safe and easily accessible.
