The fish don't complain when the whether gets icy cold, so why should you' Wear the Simms Men's Kinetic Jacket, and go catch 'em. PrimaLoft Gold insulation provides a superb warmth to weight ratio and maintains 96% of its warmth when wet, which is important when the river you're wading in would be ice if it weren't flowing downhill. A DWR treatment sheds moisture and means that, unless you take a dunking or the heavy stuff comes down, you shouldn't have to test out that insulation's warmth when it's wet. Designed specifically with anglers in mind, the Kinetic features underarm and body panels made of Polartec Wind Pro stretch fleece for a superior range of motion while casting. Simms gave this performance jacket tricot lined hand warmer pockets and a zippered chest pocket to keep your essentials from taking a cold water bath. The Kinetic's low profile, insulated hood keeps your nugget toasty and integrates with Simms' rain shell storm hoods.
