Product title: SITKA Gear Men's Stratus Windstopper Jacket
Product description: When the temperature starts to drop, and the wind begins to wind up, the new Stratus jacket is your go-to top. Built with a lightly brushed, mid-weight WINSTOPPER Fabric, for quiet, close encounters, the Stratus jacket excels. Patterned for minimal bulk and full range-of-motion, the mid-weight peice fits the bill for mid-season sessions on stand. Layer up underneath, and you're ready for the worst of weather conditions. A fully-featured hood with a separate stand-up collar coupled with key hand and chest pockets give you all that you need from a minimalist feature set perspective.
