Why It Made The List

Built in collaboration with Australian run-cap specialists Fractel, this lightweight cap combines technical performance with Acid Running’s stripped-back aesthetic. Made from quick-drying, water-repellent fabric, it keeps you cool and dry through long sessions and unpredictable weather. The short brim gives shade without blocking vision, while laser-cut side panels boost airflow. Finished with reflective branding and an adjustable cord closure for a secure fit, it’s minimal, breathable, and ready for pace; a proper performance cap with real style.

MORE DETAIL

A lightweight performance cap created in collaboration between Acid Running and Fractel, built for comfort, breathability, and all-day wear.

Made from 100% recycled polyester, it uses Fractel’s SwiftDry fabric technology to wick sweat quickly and keep the head cool and dry in heat or high effort.

Mesh side panels add ventilation without losing structure, while UPF 50+ protection guards against sun exposure on longer runs.

The soft, pliable brim can be packed down or shaped easily, and the adjustable rear strap ensures a secure fit for a range of head sizes.

An internal sweatband manages moisture at the forehead, keeping things comfortable when the pace lifts.

Finished in black with clean Acid Running and Fractel branding, the cap weighs just 59 g.

Light, technical, and ready for miles in any weather, it’s a thoughtful piece of kit that pairs performance detail with everyday usability.
