Cycling Caps

The cycling cap has a specific design logic that distinguishes it from every other cap category. The short peak folds down to block road glare and rain without obstructing vision at normal cycling head angles; the peak folds up out of the way under a helmet. The low profile and close fit sit comfortably inside a cycling helmet — a baseball cap cannot. The cotton or merino construction breathes under exertion without accumulating heat. Every design decision reflects the demands of sustained physical effort in variable weather.

Cycling caps have a direct lineage to the professional peloton. In the pre-helmet era — which extends from the birth of competitive road cycling in the 1890s through to the mid-1980s — cycling caps were the primary head protection worn by professional riders. The wool and cotton cycling cap associated with Eddy Merckx, Bernard Hinault and the classic Grand Tour era is one of the most photographed objects in sporting history. The International Cycling Union (UCI) made helmets mandatory in 2003, and cycling caps moved from race wear to warm-weather layering, post-race insulation and lifestyle wear — where they have remained, with steady increasing popularity.

Hatloom's cycling caps are produced in cotton twill, merino wool and technical blends — in the classic peak-and-close-fit silhouette that has defined the category for 130 years.

Frequently Asked Questions

What is a cycling cap?

A cycling cap is a close-fitting, low-profile cap with a short foldable peak designed for wear during and after cycling. The short peak blocks glare and rain without obstructing vision at cycling head angles; the close fit and low crown allow the cap to be worn under a cycling helmet. Traditionally made in cotton or merino wool, cycling caps are worn during rides in warm weather, after rides for warmth, and increasingly as casual lifestyle wear associated with road cycling culture.

Can you wear a cycling cap under a helmet?

Yes — the cycling cap is specifically designed to fit under a standard road or mountain bike helmet. The short, foldable peak can be turned upward (and sometimes tucked) to avoid the helmet's retention system, and the low crown profile fits within the helmet's foam structure without raising it off the head. Baseball caps and snapback caps cannot be worn under helmets due to their high structured crowns and longer peaks. A merino cycling cap also adds warmth when worn under a helmet in cold conditions.

What is a cycling cap made of?

Traditional cycling caps are made from 100% cotton twill — the material of choice for the classic road racing era caps from the 1960s through 1980s. Modern performance cycling caps use merino wool (natural temperature regulation, odour resistance), technical polyester blends (moisture management, quick-dry), and lightweight cotton-elastane mixes (stretch fit). For casual and lifestyle wear, cotton twill remains the most popular material. For performance cycling in variable conditions, merino is the premium choice.

How do you wear a cycling cap?

During a ride: peak down, covering the forehead and blocking glare and rain. Under a helmet: peak folded up or tucked, crown sitting inside the helmet. After a ride (warmth): worn flat on the head with peak forward or upward depending on preference. As lifestyle wear: peak down in the cycling tradition, or pushed up for a casual silhouette. The cycling cap's peak orientation carries cultural signal — peak-down is traditional cycling wear; peak-up reads as more casual.

Are cycling caps just for cyclists?

No — cycling caps have established themselves as mainstream lifestyle headwear independent of cycling participation, particularly within the broader streetwear and heritage sportswear market. The cycling cap's low profile, foldable peak and clean construction work well as casual everyday caps. Many people who do not cycle wear cycling caps for their visual associations — the heritage of road racing, the clean European aesthetic, the uncluttered silhouette — rather than for cycling-specific functionality.
