OC Calf Classic Gilet

The OC Gilet - Built for Fast Miles & Cold Mornings

The OC Gilet is engineered for riders who want streamlined performance in unpredictable conditions. Built with a race fit, it sits close to the body for maximum aerodynamic efficiency and zero flapping at speed. If you prefer a more relaxed silhouette, simply size up one for a comfort‑focused fit without losing the vest’s technical performance.

Our gilet is cut from a lightweight 90gsm wind and waterproof fabric, it shields your core from harsh gusts and sudden showers without ever feeling heavy or restrictive. The two‑way YKK zipper gives you full control over ventilation — open from the top, the bottom, or both during climbs and efforts.

A silicone gripper around the hem keeps the vest locked in place, even when you’re pushing tempo or riding in the drops. Branding stays clean and modern with heat‑pressed silicone logos, maintaining durability and a premium tactile finish. The pre‑dyed solid black or white fabric ensures deep, consistent colour that won’t fade, wash out, or show through when stretched.

Designed to layer seamlessly over any jersey, this gilet is an essential item for unpredictable weather and year‑round riding.

Sizing Recommendation: For the best OnlyCalves fit, we recommend sizing up one size from your usual cycling jersey size. - if you wear a Jersey size L, order an XL OC Gilet.
