Description

Cool disclosure.

We'll be among the first to acknowledge that the cycling industry can often fall victim to its own marketing hype. Castelli promises to play it straight with the Chill Arm Sleeves, freely disclosing that the cool tingling of the Xylitol incorporated in the sleeves' Prosecco Ice material is actually just a placebo. The cooling effect of the Chill Arm Sleeves — as with all similar articles — comes from good ol' evaporation.

While the sleeves don't actually make you cooler on their own, they do help you monitor your heat with Castelli branding that disappears as it heats up. This serves as an alert every bit as tangible as your heart rate monitor that it's time to wet the sleeves. Their construction is meant to absorb and hold water, prolonging the effects of cooling evaporation. A UPF of 50 provides one more anti-sun benefit on days when you'll really appreciate the reminder to keep your cool.

Good product but size isn't the greatest

  • Fit: Runs large
  • Size Bought: Small/medium

The sleeves them selves are are a great product and do what they are supposed to do. Protect your arms from the sun while not being excessively hot. Great if you have extensive tattoo work and ride in areas with extreme heat and don't wanna destroy your ink. My only complaint is they need to have a wider variety of sizing. If your a thinner rider like myself. 145 lbs they are just a tad loose. Rather strange coming from Castelli considering all their stuff usually runs small. For the price I'll keep emailing since my aunt in a seamstress and can take them in a bit.

Unanswered Question

Can you provide the size chart pls

great buy!

    Was looking keep my arm cool and protect from UV in the summer. It was better than expected. I biked with it on 97 degree hot day and it kept my arm cool all day, I think it's the new technology material does the job. now I put it on every time I go out for a long ride.

    Effective!

      Being a high risk candidate for Melanoma, I am very conscious of riding in direct sunlight. I also look for anything to keep things cool during hot rides. The Castelli Chill Arm Sleeves have a 1 -2 punch and work as advertised!
