Punisher Cool Under Shirts 2014 edition. I got mine in the 3-pack bundle, which means I can shirt-up and stay stink free for days at a time.
The shirts themselves are made from Drytech polyester and are designed to be worn under body armour, as a work-out shirt or whatever close fitting base layer you might need. Ive covered this kind of garment before in the Blackhawk! shirts and the Under Armour shirts. These kinds of materials wick moisture away from the body, helping keep you cool and also quick drying. I certainly gave this a test this year in both the Tough Mudder, and on my recent trip to Fiji.
There are even mesh panels under the arms to help with airflow, which really comes in handy if you are wearing a vest of some kind (be that a plate carrier, LBV or BCD/PFD) especially in a hot and or wet environment.
Decked out with Kryptek patterning printed onto the right sleeve, and fitted with a broad swatch of loop-field on the left, the tan material with subdued ANF for the platypus skull filler make this a cool-guy shirt that does its job. The back is printed with shout-outs to the major lines Platatac works with.
I've put this shirt through some pretty strenuous work; it's my running shirt, my Tough Mudder shirt, I wore it jetski-safariing and snorkeling. I've found it to be light, warm when needed, cool when needed and certainly quick drying.
I really liked having a loop-field to attach items from my ever-growing patch collection.
If you have need of a slick, comfortable and hard-wearing body-hugging shirt, you should totally give the CUS a try. Coyote adventure tested!
