Variety is the name of the game when you want to stay hidden. As part of an ongoing effort to give operators tactical advantages without being seen, 5.11 continues to evolve our flannel shirt line with our Sidewinder Flannel. Crafted from 100% yarn-dyed polyester flannel that offers enhanced fade and shrink resistance, easier wash and wear care, and improved weather resistance compared with traditional 100% cotton flannel. To this we've added our contrasting double weave fabric made popular on our Rapid products for distinctive styling and abrasion resistance when carrying packs and bags. The Sidewinder Flannel Shirt combines casual styling with modern tactical utility. Available in your choice of three different plaids, the Sidewinder Shirt features twin chest patch pockets and our hidden external document pockets under the front placket, providing quick and covert access to gear or accessories, cord management, and side gussets for enhanced range of motion. Specifically engineered to work with our Holster Shirt, the Sidewinder Flannel Shirt features our RAPIDraw placket system for easy access to a concealed sidearm.![]()
