SITKA KELVIN AEROLITE JACKET - WATERFOWL MARSH

The Kelvin Aerolite Jacket delivers the best of both worlds — the lightweight compressibility of down with the dependable warmth of synthetic insulation, even in the harshest wet conditions. Traditionally, synthetic insulation has meant extra bulk and weight, but this jacket changes the game.

Utilizing advanced aerolite insulation technology, it traps air efficiently to mimic the loft and heat retention of down, all while maintaining performance when wet. Designed as a versatile, packable layer, the Kelvin Aerolite keeps you warm when temperatures drop and packs down small when the sun comes out — making it an essential piece for unpredictable conditions.
