Hi Phil, There are several,"Stay-Dry", moisture wicking t-shirts and polo/sportshirts available, some with UV protection also. Brands include and not limited to: Champion, Augusta, Columbia, Devon & Jones, Anvil, Jerzees, Harriton, Izod, and Chestnut Hill. I can get these for you with or without a shooting pad, left or right hand. Sue at Pine Tree Custom Sportswear
