Giro Wind Jacket



Super-light and comfortable extra layer, but only really useful in the dry

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 Wind Jacket is a very effective and very stowable outer layer that's good as an extra buffer on cold mornings or to keep the chill off at a cafe stop. It doesn't really live up to its water resistant claims, though, which makes it less useful as a winter wardrobe item in damp UK conditions.

The Wind Jacket is constructed from a super-thin 15 denier ripstop nylon fabric. Some ripstops can be quite scrunchy and noisy in the wind, but the fabric Giro has used here has a very soft feel. That, combined with a sensibly close fit all round, means that you don't get any noisy billowing and flapping of the jacket when you're going fast, which is a definite bonus.

The sleeves are a good length and the back is slightly dropped for better coverage in a race position.

The fabric has a good level of wind resistance for its thickness and makes a noticeable difference on a cold morning, keeping the chill off until you're warmed up and ready to ditch a layer. At that point you'll be glad of the Wind Jacket's packability. It stuffs into its own captive stuff sack in no time and once in barely takes up half a jersey pocket. It's tiny, and at less than 100g it's super-light as well.

If you don't want to take the Wind Jacket off you still won't overheat as there's a full-length vented panel in the back which allows excess heat to escape. Not that the ephemeral-feeling fabric is much of a heat barrier anyway. In spite of its thickness (or lack of it) the jacket seems fairly durable, coming out of scrapes and snags with the odd pull but no major damage.

It's not much use in the rain, though. Giro claims the jacket is 'water resistant' but let's be honest, it's not. Anything heavier than a mild drizzle penetrates pretty quickly, so this isn't really like a race cape that serves as a windproof when you're setting off and an emergency waterproof layer should you need it.

It's really only useful when there's no rain forecast. On those days the quiet fabric and well-considered fit make it a first choice, but £80 is a lot to spend on an outer layer that does half the job of a lightweight waterproof shell for the same kind of money. Something like the Vermarc Extreme Rain is a similar price but a lot more versatile.

That's not to say I didn't enjoy using the Wind Jacket, because I did. It's comfortable and effective on dry, cold days. If you want a jacket just for that then it's a good choice, but most of us need our winter wardrobe to be a little more versatile.

Giro says: "The Men's Wind Jacket is an easy-to-stow, lightweight jacket for quick protection.
