The 5.11 Tactical Cams Short Sleeve Baselayer Shirt is a great CCW alternative for those times when you don't want to carry IWB or appendix-carry. The top of this baselayer looks like a typical t-shirt, making it perfect for wearing underneath a collared shirt. The upper body is made from a 4.1 oz. 60% cotton/40% polyester jersey and the a compression-fit lower body is made from 5.1 oz. 86% polyester/14% elastane jersey material. 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. Integral odor control fabric and 4mm ultralite Ortholite padding will keep you comfortable while fighting odors of sustained activity.
