Designed for demanding outdoor work, the Ariat Men's Rebar Khaki Heat Fighter Long Sleeve T-Shirt focuses on keeping you cool and comfortable when temperatures climb. It uses a lightweight technical knit that helps manage heat and moisture, with ClimateTEK technology that adjusts as your activity level changes. Greater Arm Mobility construction allows easier movement through the shoulders, and a stain-repellent finish helps the shirt stay presentable on messy job sites.
