Breathable mesh fabric resists snags and chafing on trail runs and adventure races.

Recognized as the most advanced cool mesh tee from Patagonia this Women's Airius T-Shirt is an excellent pullover for trail runs and quick day hikes. Patagonia improved the Airius knit fabric with a softer brushed interior face for improved comfort and minimal chance of chafing. The fast-drying and breathable fabric has a special ceramic component that uses UV rays to break down odors--an important feature if you're running or working out in hot weather. Patagonia moved the flat seams forward on the shirt to eliminate friction although some hikers and backpackers may find that the seam placement is not ideal for an over-the-shoulder traditional day pack. We like the Airius because the airy mesh design is perfect for going fast in hot weather--especially if you're carrying a lumbar pack.
