“Cool Shirt”

“Sizing is accurate. I bought a large since the shirt will be used in the outdoors and I wanted it to be comfortable and roomy. It is appropriately sized for this purpose and can handle a base layer underneath if needed. There are side vents as well as the cape vent in the rear and a zippered pocket hidden beneath the left breast pocket flap. The collar can extend out by undoing a couple of velcro fasteners. I guess it's for cool or hot sunny days to protect your neck. Seems superfluous, but could come in handy when needed. It doesn't detract from fit or comfort.”
