"Bought this Jacket just after Xmas, used not only for general wearing but as my go to waterproof top for wet cycle rides. It ticks the boxes completely. 100% waterproof as expected ( and main reason for purchasing) matched with impressive breathability. For very cold wet days off the bike it layers great over my down jacket and base layers. It still breathes retaining warmth and leaving me dry at the end. Off to Scotland bike packing in Feb. Pretty sure I'll be wearing it constantly, if not it packs down so small. Huge bonus, great jacket. Size wise fits true to size. I chose large. I'm a 42 chest and this allows layering as described."
