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

BTwin's 300 Warm Cycling Jacket is designed for cold, dry and murky days. The materials might be a little on the basic side and wicking is slower than more sophisticated blends, but there are some lovely touches and it delivers plenty of smiles per mile.
As regards the fabric, it's a 90/10% polyester elastane mix with a really tactile fleece liner, and the back panel is supposedly thinner to promote efficient dispersal of rider-generated heat.
Sizing is quite generous – as a rule of thumb I'm a large in most jersey/jackets but our medium was absolutely bang on. It was snug, but with sufficient length in the arms and tail.
The pockets are unusual, and generally in a good sense. There are three in total, two massive ones at the rear, which managed two spare tubes, a large multi tool, energy bars, tyre levers, a 600ml trade bottle and mini pump.
The left breast panel of the jacket incorporates a Tardis-like nelson-type pocket big enough to cope with a medium wallet/smartphone or, to my delight, super zoom travel compact/mini CSC cameras.
Scotchlite detailing is limited to logos on the lower back and arms, but the orange really burns through the murk, nabbing oncoming traffic's attention at the 300-500m mark in semi-rural contexts. Something to consider if you were thinking you'd prefer the black option, maybe.
The orange version does have contrasting black panels which I like; the sleeves are still highly visible and so it won't matter if you commute with a messenger bag or rucksack. I have been inclined to post a blinkie on the pocket when navigating unlit semi/rural areas after dark, though.
Road spray and similar organic grime doesn't tend to stick to the jacket, but catching the cuffs against the bike's drivetrain or bringing it into contact with grimy digits did leave faint, smudgy calling cards. Mercifully, machine washes at 40 with a full prewash keeps things crisp.
Given the asking price, performance has exceeded my expectations by a long shot.
Climate control/moisture management is best described as fair, and I was very grateful for high quality merino baselayers in milder temperatures, but I never felt 'boiled in the bag' and ventilation is easily tuned by dropping or raising the front zipper.
Predictably, things do turn a little clammy around the armpits and lower back given 20 minutes at 18mph plus, but less than you'd expect when the mercury's trying to hit 12-13 degrees. Thankfully, by this point the rear panel's kicking in, reducing this to a warm glow. Mind you, on longer rides if you're carrying a rucksack and/or wearing a budget baselayer you can expect this to linger.
The additional warmth the jacket provided was greatly appreciated on late night/dawn runs when temperatures struggled beyond 6°C. The insulated front panels offer excellent protection against icy blasts and persistent chill, and the elasticated inner cuffs also prevent cold and potentially very wet stuff being scooped inside.
Speaking of wet, the outer layer fended off persistent showery rain for a good hour, although I'd still carry a micro jacket on day rides, or if rain was forecast.
Ultimately, the 300 has been a really pleasant surprise. Moisture management doesn't match more sophisticated fabrics, but it is remarkably close to some costing twice as much. At this price and for cold, dry conditions it's hard to see where you'd go wrong.
Nicely designed budget jacket for cold and generally dry weather

Tell us what the product 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?
BTwin says: "THIS MEN'S CYCLING JACKET OFFERS GREAT PROTECTION FROM THE COLD IN AUTUMN AND WINTER WITH ITS INSULATING MEMBRANE ON THE CHEST AND WARM FABRIC AT THE BACK."
It does just that.
Tell us some more about the technical aspects of the product?
Jacket made out of warm fabric with wind-breaking fabric at the front
Lightweight fabric at the back for good ventilation
Reflective zones on the shoulders and pockets at the back
2 pockets at the back, 1 zipped breast pocket
Rugged and nicely thought out.
While moisture management can't compete with more sophisticated synthetics in milder conditions, it's by no means bad, and cold weather comfort is excellent. Micro jackets are a sensible move on longer rides, though the outer shell proved surprisingly shower resistant.
Jersey cum jacket, so a baselayer is all you'll need underneath. It can be a bit too cosy in milder conditions though.
