It’s also a perfect antidote for arid conditions when travelling. The **patented\* knit structure** of Polartec® Delta™ elevates touch points so that the **fabric sits slightly raise**d, rather than lying flat against the skin. This **increases airflow**, **hastens moisture dispersal**, **reduces cling** when wet. And with a UPF 50+ rating, it also helps **protect you from harmful UV rays** during long days outdoors. As a result, the **Oryon Delta Lite Long Sleeve Tee**, which is also available in a short-sleeved version, delivers **next-to-skin comfort in high-heat** while maximizing performance and minimizing weight. All of which allow you to move freely and stay focused regardless of the terrain, temperature or intensity. In addition to its **innovative cooling performance**, the Oryon Delta Lite Long Sleeve Tee is designed for lasting comfort when the pace doesn't let up. **Merrow active seams**, **a bonded neckline and stretch side panels complete a design built to move naturally** with the body without creating unnecessary bulk or restriction. Engineered to excel when spending time beyond the beaten track, the Oryon Delta Lite Long Sleeve Tee keeps working when the sun burns hot. Available in Lunar Grey, Obsidian Black and Steel Blue in sizes XS to 3XL. \* US Patent No. 11,840,782 [ Get it now. ](https://www.thrudark.com/products/oryon-g2-delta-lite-long-sleeve-tee-lunar-grey) Share.
