It's so good, two of my mates have bought them since seeing mine.
So far I've worn mine with a thin base layer on days where the temperature is between 5 and 10 degrees C. It's perfect for that, stops the wind and provides a bit of warmth, but not as much as my 7Mesh Cache anorak. It's really breathable too.
It's a snugger fit than the 7 mesh top, I'd size up if you want to wear more layers under it. The sleeves are a similar length.
Really fast delivery from 20Twenty too!
