"Well done, very well done. High quality fabric, fit and finish. I highly recommend this shirt!" says Ed in New Jersey. Who talks like that about a "basic" thermal shirt? Someone who shops 40 Grit Clothing by Duluth. The 40 Grit® Thermal Long Sleeve Henley looks good and comes in a just-right weight. Has all the comfort and features you want, so you can get on with building, inventing, adventuring. No skimping here on the neck trim and cuffs – stretchy rib-knit stays in shape, wash after wash. The one thing that is basic? The best-value everyday price.
