Cooling, moisture-wicking Hattie Short built for high-output trail performance
What Our Gearhead® Experts Are Saying:
"I was shocked at how breathable these were on hot, sweaty trail days. They feel supportive but not restrictive, and the cooling tech is legit—I didn’t overheat, even on big climbs."
From sunrise trail runs to midday climbs, the Hattie Short is built for those who never slow down. Engineered with brrr° cooling technology, these shorts actively lower your skin temperature, wick moisture, and dry quickly so you stay cool and focused—even during the sweatiest sessions.
A streamlined fit made from recycled polyester and spandex delivers supportive compression without discomfort. Designed with an interior key/card pocket and a gusseted crotch for mobility, the Hattie is ready to ride, hike, run, or stretch. Lightweight, flattering, and packed with performance, this short redefines what active comfort feels like.
