BTwin 500 Women's Waterproof Jacket



Excellent value lightweight windproof and waterproof jacket

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.

At just £25, the BTwin 500 Women's Waterproof Jacket seems a real bargain. BTwin is the own brand of sports superstore Decathlon. The jacket has a good cut, feels comfortable and has some good features such as the mesh-lined ventilation gussets at the front of the shoulders and on the back. It's a great lightweight, high-vis waterproof to stuff in a jersey pocket or wear on your commute from spring through to autumn.

The 100 per cent polyester fabric keeps the wind off and is remarkably breathable – I noticed a bit of clamminess on the inside of the lower sleeves after riding hard, but no more than with far more expensive jackets such as Endura's Luminite and Altura's NightVision. There's no mesh lining on the inside of the jacket, which keeps the weight and bulk down, and it feels fine against the skin – I'd happily wear it over a T-shirt.

The jacket also scored highly for waterproofness. Given a lack of sufficiently heavy rain, I tested it by standing under a fairly powerful shower for about 10 minutes and was amazed how the water ran off it like the proverbial duck's back. A quick shake and the material was all but dry. And despite aiming the shower at the lower sleeves – an area I often find water soaks through on other jackets – my arms remained dry as a bone, as did the rest of me. Quite impressive given that Decathlon rates it for only two hours' wet weather. The seams are all taped inside too, which prevents water ingress through the stitching.

The fit is fairly flattering without too much excess material, although I had to go for a medium/large (UK 14/EU 42) when usually I'm a small or medium size, in order that the shoulders didn't feel constricted when in the riding position. It's a good length in the body and isn't too short at the front, which I prefer. The drop tail protects your bottom from tyre spray.

The sleeves could be one or two inches longer – they're all right if you ride in an upright position but creep up if you're more stretched out (and exposed wrists are my pet hate). There are narrow elasticated cuffs that are the right tightness, and the hem is slightly elasticated too.

I thought at first the neck was maybe a bit big, but in fact on the bike it felt quite snug, although it gapes slightly at the back of the neck in the riding position. The collar is nice and tall, too.

Aside from the fluoro colour, which should make you immune to SMIDSYs (sorry mate I didn't see you), one of the notable features is the slightly off-centre zip. I'm not sure this makes any difference to comfort but it looks quite nice. There's a storm flap behind it and a garage at the neck to prevent the zip rubbing your skin.

As well as the ventilation gussets there are perforations on the sides below each armhole to let moisture out. Some more holes on the underneath of the sleeves would have aided breathability.

There is a zipped pocket with storm flap at the rear, big enough for wallet, phone and keys, and the jacket packs away into it too. I'd ideally like a front pocket for easy access to keys and train tickets, but you can't complain at this price. For night-time visibility there is a large BTwin logo front and rear, reflective piping on the back and lower sleeves, and a reflective strip all around the hem.

All in all, it's a truly great jacket for the money.
