On the hottest days, reach for this tee made of moisture-wicking, breathable Coolmax jersey: a fade- and snag-resistant material that moves moisture away from your skin to foster evaporative cooling. With an active fit and Solar Blocker Plus technology, you also get UPF 50 sun protection that repels radiant heat, as well as an anti-odor treatment that helps keep body odors at bay. The spandex ribbed collar holds its shape no matter how wet it gets, while tagless labeling leaves one less itch to scratch.
