Patagonia's sun base layer
Patagonia launched the Capilene Cool Sun base layer this March with 97.5% UV protection and advanced sweat‑wicking — built for variable conditions and long treks in places like Patagonia (t3.com). The lightweight, sun‑blocking layer is being highlighted this week as essential kit for spring and summer trekking where UV and heat management matter (t3.com).
Patagonia specifies the Capilene Cool Sun styles use a 3.5‑oz, 100% recycled‑polyester jersey with a single‑knit construction that the company says creates a durable, built‑in sun‑protective effect that won’t wash out. (patagonia.com) Retail pricing on Patagonia’s site shows the long‑sleeved Cool Sun tee at $79 and the standard hoody at $89 in the U.S., with printed/variant hoody styles listed up to $99; product style numbers include 44790 (long sleeve) and 44800 (hoody). (patagonia.com 1) (patagonia.com 2) Design details aimed at active use include a textured back to lift the fabric off skin for airflow, thumb holes at the cuffs, a generous hood engineered to fit over a ball cap with a button closure, and a vertical zip chest pocket with a corrosion‑resistant zipper. (patagonia.com) Patagonia lists the Capilene Cool Sun pieces as made in Fair Trade Certified™ factories, noting workers earned a premium, and the product pages link to Patagonia’s Ironclad Guarantee and Worn Wear repair/recirculation options. (patagonia.com) The Cool Sun collection is presented as a new arm of Patagonia’s Capilene® Cool family for Spring/Summer 2026, joining other Capilene Cool variants such as Cool Ultra in the season’s rollout. (patagonia.com) (outdoorgearzine.com) Patagonia lists men’s and women’s Cool Sun hoody and long‑sleeve styles across its regional sites (U.S., EU/UK, Canada) and shows multiple colorways and X‑dye prints for the season’s lineup.
