I'm extremely happy with this jacket which I've been wearing for 6 months of winter riding on gravel and back roads in the Scottish Borders. The large size fits me (100cm chest and 94cm waist) perfectly with room for a thermal base layer. The arms are quite snug but there's enough stretch in the fabric so they're comfortable when riding. At times it's been a bit sweaty riding hard uphill and a bit chilly on long downhill sections but I think the balance between insulation and breathability is as good as it gets for a winter jacket and the underarm vents do make a small difference. I try to avoid riding in the rain but when needed it's coped fine with heavy showers and longer rides in damp conditions. Design team please note, you pretty much nailed it so don't mess with it...

First of all great jacket with fantastic quality and features for the price. I ordered a medium based on the website sizes but had to return it and get the large which fitted. By the way the returns process was so easy.
