Giro SPF 30 Ultralight Cap



Lightweight cycling cap ideal for the spring and well into the summer

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Giro's SPF 30 Ultralight Cap is an extremely lightweight cap that keeps your head drier than without and also provides sun protection, especially handy if you're follically challenged.

It's designed and styled like a regular cotton cycling cap but is made with an X-Static Performance mesh panel, a fabric typically used in jerseys, while the side panels are Power mesh. The two fabrics in combination provide an airy cycling cap that works well to combat sweat buildup, and keeps you drier versus not wearing a hat. Because it's so airy, you don't feel too warm wearing it.

A simple multi-panel design and the thinness of the material means it slips unnoticed under a helmet. The small peak is good for keeping the bright sun out of the eyes, with the added benefit of funneling sweat away from your forehead - it drips off the end of the peak rather than running down your forehead and collecting in your shades.

As well as using it on warmer days, I've taken to wearing it for early morning and late evening rides when there's a chill in the air. It provides a tiny bit of extra insulation without any risk of overheating.
