The McKenna Tech Shirt is an ultra-lightweight layer that’s built from a soft cotton/poly blended fabric that’s naturally moisture-wicking and quick-drying. And to keep you even cooler and more comfortable on the job, we added side mesh panels for maximum ventilation. It’s the ideal layer for anyone who works outside, especially landscapers, masons, roofers, and turf managers. Buy three of these tees today, and we’re giving you a fourth for FREE.
