The Strata 200 Crew completes the Simms layering system for cold and unstable conditions. Its fluted knit promotes heat retention while limiting moisture build-up during active phases. Raglan sleeves and flat seams offer freedom of movement and lasting comfort under the upper layers. Integrated thumb loops and a discreet collar make it easy to wear under a waterproof jacket, without creating unnecessary thickness. A reliable layer to stay effective longer on the water.
