Made of 100% polyester, this performance polo shirt has a slight sheen and stays looking good day in and day out. Weve included all the features of our cotton Tactical Polo including mic clips, fully gusseted sleeves and pen pockets on the left sleeve. The Performance Polo shirt fabric is moisture wicking which prevents the growth of odor causing bacteria. Made with our proprietary SmartWeave fabric, the Performance Polo Shirt resists snags and remains wrinkle free. You can attach your radio microphone to any of the three mic clips on the shoulders and chest placket. The Performance Polo Shirt has two pen pockets located on the left sleeve. The synthetic fabric of the Performance Polo Shirts resists stains, tears and snags. The no roll collar has flexible stays which keep the collars from rolling at the edges. The pen pockets are stitched to endure constant use and all seams are designed for both comfort and durability. 5.11 Tactical Series uses only melamine buttons on the Performance Polo Shirt. Melamine buttons dont crack or break and can withstand the heat of an iron without melting. The stitching and materials used in the construction of the Performance Polo Shirt are of the highest quality demanded by Law Enforcement, Fire and Military personnel. The 5.11 Performance Polo Shirts are the ultimate in comfort and fit. Weve added fully gusseted sleeves to give you full range of motion even when wearing your ballistic vest. Because the Performance Polo Shirt does not wrinkle, shrink or fade, it is an exceptional value. Most polo shirts on the market can be worn only a few times before losing their professional look. Our proprietary SmartWeave fabric keeps its slight sheen even after multiple washings and the fabric wont snag or peel, giving it a long life. The Performance Polo Shirt outlasts other polo shirts by such a great factor and is so reasonably priced; it just makes sense to wear the best.
