The McKenna Long Sleeve 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 in the heat, 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 tech shirts today and we’re giving you one for FREE.
