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.

Altura's Firestorm bib shorts have a pad that works very well, sizing that's spot on and fabric that wicks away sweat very efficiently, making them a really good budget-conscious choice. The fabric may be a bit too stretchy in critical areas, though, plus it can bobble fairly easily against the seat.

The main fabric on these shorts is an 82% nylon/18% spandex mix in the usual six-panel pattern. The straps are mesh both on the front and the back, with a section of solid elastic on the shoulders and chest. I found these straps comfortable, and less sweaty than shorts without mesh.

The shorts use Altura's Stealth pad, which uses open cell foam under the polyester top fabric. The foam is thicker at the contact points and reduced in other areas for padding without bulk; there's a whole section on Altura's website about the '3D' shaping, but I'll summarise it for you: it's very comfortable and about as breathable a pad as I've come across for this level of support.

The legs are kept in place with a roughly 4cm-wide rubberised hem around the front, and around three-fifths of it gets silicone gripper (it's not grippy around the back). It works well without restricting leg movement, giving good security against them riding up without becoming too tight.

I'm 178cm (5ft 8in) and weigh 77kg; medium bib shorts fit me well in non-Italian brands such as Endura or dhb, and the Firestorms in medium are bang on the money.

I get on less well with the fit. The Firestorms are supportive at the hem and around the outside of the thighs, but the front two panels are very easily stretched. Around the crotch, the shorts feel too loose and stretchy, like it's a slightly different or thinner material – perhaps to increase breathability. I would prefer things a bit more snug.

Having said that, these shorts perform well, including on longer rides. I had no complaints from the nether regions on 4-5 hour rides in pretty hot weather.

I've had no issues with washing, though there is a bit of bobbling on the fabric under one side of the pad. I don't know why this only shows on one side; it doesn't look like it will affect durability or performance, though.

At £69.99 they're a fiver cheaper than dhb's comparable Aeron shorts, which are a good benchmark for top quality affordable shorts.

There's a lot to like about the Altura Firestorm bib shorts; the pad is really comfortable, they're well put together and they deal with sweat better than most. The only downside is the unsupportive front panels, though you may well be happy to live with that as it doesn't affect performance or comfort while riding.

Tell us what the product is for

Altura says: "When the thermostat pops, these Firestorm bib shorts will still be giving you comfortable all-day comfort. Instead of letting the sweat build up sweat inside, the special fabric wicks moisture away to keep you feeling fresh. While the upper body provides enhanced ventilation thanks to the minimal mesh lining.

The all-important pad is our specially-designed Stealth insert, providing shock absorption and avoiding friction with its close to skin flat surface comfort . The sleek and close-fitting cut is comfortable without feeling restrictive. Instead of tight elastic, special silicone grip printed inside the hem ensure the shorts stay in place.

The Firestorm bib shorts also offer enhanced visibility with a reflective hem gripper that reflects headlights in dark or low-light conditions."

Overall, there's a lot to like for the money. They're comfortable on longer rides and keep the sweat wicked away. My only gripe is that the fit could be more supportive – they're good, and a solid 7.
