What Our Gearhead® Experts Are Saying:"I throw on the Circuit Hoodie for just about everything—morning trail runs, crag approaches, or long drives. It’s soft enough to feel like a lounge layer but performs like a technical piece. It dries quickly, resists odor, and offers solid sun protection, so I never have to think twice about packing it."We reach for the Black Diamond Circuit Hoodie when the day promises movement and comfort in equal measure. Designed for climbing-inspired versatility, this ultralight pullover keeps us cool and protected through sunny approaches, casual runs, and relaxed rest days alike. The buttery-soft stretch fabric wicks moisture, dries quickly, and features an anti-odor finish for long-lasting freshness on multi-day adventures. UPF 40+ protection shields us from high alpine rays, while the eco-conscious design uses recycled polyester to lessen environmental impact. Whether pulling it on for an early crag session or staying comfortable on travel days, the Circuit Hoodie delivers easygoing performance from dawn to downtime.
