How we test

At road.cc 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.

What the road.cc scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Castelli UPF 50+ Light Arm Skins are a decent set of sleeves that keep the sun off and offer some protection on descents.

  • Pros: Lightweight, keep the sun and some wind off, easy to use and stow
  • Cons: A little pricey for what they are, perhaps

As the sun comes out, so too do the razor sharp cyclist tan lines and the realisation that despite the ride starting under clouds, you are now in bright sunshine with no suntan lotion. This is the kind of situation that the Castelli UPF 50+ Light Arm Sleeves aim to stop.

They're a simple construction of a polyester based material in a tube with the two sides stitched together along a single seam.

The material used is stated as UPF 50+ so it doesn't let harmful UV rays through to burn your skin, although according to Castelli they actually block out 99.8% of harmful rays. I used these on some days with fairly intense sun and nothing got through, so they seem to do what they're designed for. 

They aren't just useful for keeping the sun off, though. Okay, they aren't the warmest of warmers, but they do keep the worst of the wind off your arms on descents, and I also used them a couple of times on early morning rides. 

> How to protect your skin from the sun

They're very light too, so it's a no-brainer to stick them in a jersey pocket when it's not too sunny, as they can provide a little extra protection on the other side of climbs.

Despite the simplicity of the design there are some nice elements such as the silicone gripper at the top of each sleeve both inside and out, so they hold on to your skin and the sleeves of your jersey.

An RRP of £25 puts them on par with many of the warmers we've tested on road.cc, a little higher than some, a little lower than others, and given their usefulness as both sun and wind protection, they go some way to justifying it. Sugoi's similar offerings that David tested were £24.99 in 2013, although the Castellis don't claim to cool...

Overall, I found them to be really useful, both at keeping the sun off my skin and giving a little protection against the wind. Yes okay, as David pointed out a bottle of suntan lotion is cheaper, but that won't keep your arms warm on the downhill...

Verdict

Simple but versatile sleeves that are useful for keeping off the sun or the wind

Make and model: Castelli UPF 50+ Light Arm Sleeves

Size tested: Medium

Tell us what the product is for

Designed to keep the sun off your skin on sunny days, but also doubles as something to cover your arms to partially protect against the wind.

Castelli says, "Surprisingly useful - We can officially only rate these warmers at UPF 50+, but in our laboratory tests they actually blocked 99.8 percent of damaging UV rays. We used a polyester base that is not only more effective than nylon at blocking UV rays but is also much better at keeping you dry, which means these skins are better in both cooler and warmer conditions. We've kept the construction very clean to eliminate seams that can rub, and we used our double-sided silicone elastic to make sure they stay in place. They fold up extremely small, so they're great to stick in your pockets for your next big mountain day."
