This RBX Active Men's Long Sleeve Crew Neck Waffle Knit Thermal Shirt is the best post workout outfit. The set-in shoulders provide an active and clean fit and the articulated seams create a tailored fit to flatter your shape. The Flatlock seams reduce rub and irritation while the X-Dri moisture-wicking technology dries sweat quickly to reduce chafing. Pair it with your favorite workout baselayer or wear alone in the cold weather.
