White Ultralight Long-Sleeve UPF Shirt With UV Protection

Engineered for sun-drenched days and effortless protection, the Ultralight UPF Activity Shirt by Kolibri redefines functional menswear. Featherlight and breathable, this long-sleeve layer delivers powerful UPF sun protection without weighing you down — making it an essential for boat outings, beach runs, or poolside lounging.

Cut in crisp white for versatile styling and maximum heat reflection, it features a relaxed silhouette that layers easily over swim trunks or shorts. The subtle Kolibri hummingbird emblem at the chest adds a polished touch while reinforcing the brand’s commitment to conscious, purpose-driven design.

Crafted for men who prioritize both skin health and minimalist aesthetics, this shirt is more than protection — it's a smart, year-round staple in any elevated outdoor wardrobe.
