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 Assos Mille GT Wind Jacket is super compact in your pocket and more closely fitted than most wind/emergency jackets once on. That makes it ideal for donning before an Alpine descent or, in the UK, just keeping out the chilling winds, road spray and even light showers. It's expensive, though, so be prepared to spend extra to avoid flapping material.
Dressing for mixed conditions has always been tricky, hence low-bulk wind-blocking layers that can easily be removed being so popular. Unfortunately, during testing I didn't locate many Alpine descents – for which this would be ideal – so instead wore it for early starts and to and from the local group ride.
The key to a great wind jacket is that it can be easily stashed away, and here the Mille GT excels. The foil ultra-ripstop fabric is super thin and packs down into a tiny parcel, but still delivers the required protection once you need it.
It's cut to Assos' regular fit, but even so I found it less baggy than just about any other wind jacket I've tried. I'm normally towards the bottom end of a size medium, and this medium fits well over a few layers, but it's definitely more Italian sizing than Swiss. If you're on the cusp, size up.
Hunched in an aero position and bombing down descents, the jacket is mysteriously quiet. Obviously, a lot of that is down to its slim fit, but Assos actually says it's designed to be 'acoustically innocuous'. Happily, it is noticeable rather than just marketing guff.
The camlock on the full-length zip means it can be locked partially open; this might sound trivial, but lightweight jackets do have a tendency of opening themselves if left slightly undone.
It's surprisingly breathable for a windproof jacket, though, so you may not need to. The material under the arms and down the sides is more breathable than the main stuff, the elasticated cuffs keep the elements out without being restrictive (even over layers or gloves), and the collar offers decent protection without feeling claustrophobic.
The Durable Water Resistant (DWR) coating does a good job of keeping road spray out, and can even fend off patchy drizzle.
You won't find any pockets or access slots on the rear, which improves the fit but won't be for everyone. There are a few reflective tabs, but if you're after more visibility it's also available in bright orange or green.
With an RRP of £110, the Mille GT is certainly not cheap; we've tested plenty of more affordable wind jackets just this year. The Bontrager Circuit, for example, is now £74.99, while the Altura Icon Rocket is £80.
Nevertheless, for me the premium is well worth paying as it's far more breathable than many, the close fit doesn't flap around, and it's extremely packable. For performance it's on a par with the Rapha Classic Wind Jacket, and that's actually a fair bit more at £145.
So while this is pretty expensive for a windstopper, the performance, usability and quality mean it earns the price tag. You can easily buy cheaper, but they just won't be as good.
Compact, windproof and a really great fit – it's worth the high price

road.cc test report
Make and model: Assos Mille GT Wind Jacket
Size tested: Medium
Tell us what the jacket is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Assos says, "A windproof, lightweight shell jacket engineered for maximum protection and minimum bulk."
I agree. The price and close fit mean it's best suited to keen cyclists worried about being aero and putting the miles in.
Tell us some more about the technical aspects of the jacket?
Foil Ultra: A windproof, water-repellent, ripstop, lightweight and hyper-stretch woven fabric.
Rustle-free: This piece of apparel has been designed to be as quiet as possible with a rustle-free fabric
DWR: Treated with DWR (Durable Water Repellency) to protect you from rainfall
Full-length camLock zip: Slim, light zip for individually adjusting to the conditions
Ultra lightweight, ultra-packable: Designed with the lowest possible weight and great packability
Great at keeping chilling winds out, is an excellent fit and packs down small.
The stretch means it stands up to rough handling. As with most garments, the DWR will wear off over time.
It's water resistant but not waterproof.
It comes up quite small; if you're a big build or between sizes, go up.
It's more expensive than many, but does a better job.
How easy is the jacket to care for? How did it respond to being washed?
Tell us how the jacket performed overall when used for its designed purpose

Use this box to explain your overall score
This is a great bit of kit. The quality of its fabrics and fit – plus its first-rate breathability and tiny bulk – justify the price tag, even though it's on the high side.
