The G. Loomis Short Sleeve Tech Tee is sustainably sourced and constructed using recycled polyester material. Each G. Loomis Tech Tee shirt is made from REPREVE material that utilizes approximately 16 plastic water bottles during construction. And while this tech tee aims at helping with sustainability, this recycled material still boasts the same performance as other standard tech fabric, including UPF 50 sun protection, advanced moisture-wicking, and an anti-microbial zinc-based coating that kills odor-causing bacteria. Stay cool, dry and sunburn-free with this environmentally responsible G. Loomis Tech Tee.
