StayCool 2.0 Training Reflective Short Sleeve Tee
Built for active days that move easily from training to daily wear, the StayCool 2.0 Training Reflective Short Sleeve Tee combines cooling comfort, flexible stretch, and clean everyday style.
Made with exclusive PBS™ Fabric, it blends Pima cotton, bamboo fiber, and Sorona fiber for a soft, smooth, breathable feel with a cool-to-the-touch finish. The center-back reflective strip adds visibility in low-light conditions, making it ideal for commutes, evening walks, light training, and everyday movement.
A ribbed crewneck, slightly curved hem, and durable three-needle stitching give the tee a clean, polished finish while helping it hold its shape through frequent wear.
