The Columbia Women's Long Sleeve Sun Tee is a lightweight, performance-focused sun-protective shirt designed for outdoor activities in warm weather. Built with Columbia's Omni-Shade™ technology and Broad Spectrum UPF 50 sun protection, it blocks harmful UVA and UVB rays to keep skin safe during extended time outdoors. The Omni-Wick™ moisture management system pulls sweat away from the body to keep you cool and comfortable.

Made from 100% lightweight polyester (approximately 135 GSM), the tee is breathable and quick-drying. It's available in three colors — White, Blue (Serenity), and Pink (Peach Blossom) — and sizes ranging from XS to XXL. The fit runs slightly oversized; reviewers recommend sizing down if you prefer a more fitted look. Care is simple: machine wash cold on the gentle cycle, tumble dry low, and avoid bleach, fabric softener, and dry cleaning.
