Designed to move and breathe with you, the Kelvin LT Hooded Jacket is our most agile insulation for early-season hunts, cold mornings on the water, scouting missions, and every other trip into dicey weather.PrimaLoft(R) insulation is concentrated in the core to deliver more warmth where you need it most, and it stays warm in the wettest environments. We added STORMFLEECE(TM) side and underarm panels to breathe better during hard climbs and give you greater mobility for scrambling, shooting, and casting.
