Giro Zero CS Mitts



Very good minimalist design for those who like to feel everything coming through the handlebar

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.

The Zero CS gloves are Giro's latest version of its pro-level glove for riders who want minimalism when it comes to their hand coverings. You get a small amount of protection should you crash but with none of the ride feel from the bike taken away.

  • Pros: Great breathability, excellent fit, like riding bare-handed
  • Cons: Minimal crash protection, the white gets dirty quickly

Now this is my kind of glove. A pair of mitts that are so thin you lose nothing from the ride through thick gel padding, with such a good cut and fit that there is no bunching of any material or irritation from Velcro cuff fasteners. If you've read some of my other glove reviews you'll know that I often ride with bare hands because I like as close a connection to the bike as I can get, and these are about the best I've found.

With a thin mesh upper these mitts have been great during the recent heatwave, letting the breeze remove any sweat and heat from your hands as it passes over. The fabric has a close fit but with so much stretch that it moves with your hand, never feeling overly compressive.

The fingers are snug too, to stop any slippage, but the thumb gets a more relaxed fit for unlimited movement and I found the contrast very comfortable.

The fabric used for the palm isn't exactly a lot thicker than the upper but it's tough enough to offer some abrasion resistance and it's really well cut. Don't expect a whole lot of padding, though. High-wear areas, where you are going to be holding the handlebar, are covered, and the heel of your hand – the part that is likely to hit the tarmac first – has a more robust material to stop road rash.


The cuff section is quite large and uses a section of fabric with a high elastane level which fits snug. This means that once on everything stays in place so you don't need any straps or anything for retention.

On the palm side there is a small tab for pulling them on, and for removal there are finger tabs but unlike most gloves they are on the top rather than between the fingers. It's a clever design as I often find loops and the like between or beneath the fingers can get in the way when riding. You need them, too, as getting the gloves on and off can be a little tricky because of the close fit.


As usual, less costs more, but the Giros at £29.99 aren't overly expensive considering the quality and performance. In a similar vein are the Lizard Skins Aramus Elite gloves which'll set you back £25 for minimal padding. If you want some kind of shock absorbancy then there are the GC versions for £30.

Size-wise there is a good spread: S-XXL, or 178mm to 267mm palm circumference. There are quite a few colour options too: Dazzle Black Reflective, Blue Jewel, White, Black/Highlight Yellow and Black.

The only thing I'd say about the white is that they don't stay clean for very long, you'll be washing them after every ride, but fair play to them they do scrub up okay.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
