In our ongoing effort to provide operators tactical advantages without being seen, 5.11® offers covert, casual styling with intelligent utility in the 5.11 Sidewinder Shirt. We began with 100% yarn-dyed polyester flannel with DWR finish for enhanced fade and shrink resistance, easier care and improved weather resistance. Then we added our contrasting double-weave fabric made popular in our Rapid line for distinctive styling and abrasion resistance when carrying packs and bags. The Sidewinder is also specifically designed to work with the 5.11 Holster Shirt, with our RAPIDraw™ placket system for easy access to a concealed sidearm. Choose from 3 plaid options, all featuring solid Grenade shoulder panels, to mix up your covert wardrobe.
