Built from a stretch cotton/poly chassis, the SOFARI(TM) Ops Short Sleeve Shirt is all go-time. Underarm laser perforation provides maximum ventilation while zippered chest pockets keep your EDC on lock. The unique patterning moves the conventional side-seam from a vertical position to a diagonal seam stretching from shoulder to waist - a small detail that pays spades in fit and function. The SOFARI is low-key enough for a day of tactical cubicle crawls but robust enough should you called back to active duty. Breathe in, push out, and make sure your button-up doesn't let you down.
