The Sitka Kelvin Aerolite Jacket - Men's is a lightly insulated jacket that is versatile for the outdoors. Hunting trips are always met with a change in weather conditions, expected or unexpected, so remain prepared with a piece that can be worn alone or as a mid layer. The synthetic PrimaLoft Gold Insulation with Cross Core technology is warm, lightweight, compresses for packing, and even provides warmth when wet. The 20D polyester shell is durable and light, and a durable water repellent finish sheds light rain or snow. Finished with stretch cuffs and a fitted hood for sealing out drafts, it'll be all about the hunt instead of fussing with comfort levels.
