This is Prois' signature shirt. It has an athletic cut with a soft and durable technical composition. 100% polyester wicking fabric wicks moisture from the skin to maintain warmth and dryness. Thumbholes at the cuff line designed for warmth and camo coverage. It's a great shirt for archery or rifle seasons as you can wear it by itself or as a thermal layering option. Please note…as this shirt is engineered with an athletic cut, it tends to have a shorter fit. If you are longer-waisted or desire additional length to tuck shirt in, the manufacturer advises sizing up.
