Patagonia Ultralightweight Ridge Peaked Cap Built from 100% recycled polyester ripstop, the Patagonia Ultralightweight Ridge Peaked Cap is engineered for maximum breathability. Laser-perforated panels allow heat to escape fast, making it ideal for tempo runs, long brick sessions and summer triathlon training. The quick-wicking internal sweatband manages moisture and temperature, helping prevent sweat from running into your eyes when the pace picks up. A dark, glare-reducing underbrim cuts eyestrain in bright conditions, whether you’re chasing a PB on open roads or grinding through exposed trail miles. Comfort and practicality are just as dialled in. The side-adjustable elastic closure offers a secure, bounce-free fit with enough stretch for all-day comfort. Its lightweight foam brim folds down small, so you can stash it in a pocket, race belt or tri-suit between sessions - and it springs straight back into shape when you need it.
