The 5.11 Men's Cams Short Sleeve Baselayer Shirt is an outstanding concealed carry alternative to IWB or appendix carry. It's built with a tee style upper body use a 4.1 ounce 60% cotton/40% polyester jersey above a compression-fit lower body. Both are moisture wicking, but the top looks like a typical, everyday t-shirt - perfect to wear beneath a collared shirt or similar garment. A body pocket on either side for firearm and/or accessories provides a quick, comfortable, extremely low visibility solution for a firearm in any sort of casual or off-duty environment. The integral odor-control fabric and 4mm ultralite Ortholite padding will keep you comfortable while fighting the funk of sustained activity.
