Lightweight and ultra-breathable, the Alpine Short-Sleeve Crew Tee features an innovative hybrid construction that promotes optimum climate control on fast hikes. The North Face's exclusive FlashDry technology works with your body to wick away moisture and dramatically improve drying time. This packable, next-to-skin layering tee features geometric FlashDry mesh panels at the underarms and across the back. Built-in UPF 30 sun protection helps shield your skin against harmful rays, while flatlock-stitched seaming eliminates chafing and allows for easy layering. This hike-ready tee is backpack-compatible thanks to seam-free shoulders and hip panels. Full underarm and side gussets offer increased mobility for even greater comfort. Body: 100% polyester double-knit fabric. Panels: 93% polyester, 7% elastane jacquard fabric with FlashDry fibers. Imported.
