Used for a trip to the french alps July 26 when both the UK and europe had some high temps. The jacket flt comfy with the waterproof liner and back protector in place, a little looser as you'd expect when the liner was remove, which it was for the whole trip. I wore with long sleeve sun block vest from Lidl which ticked the box. Armour felt comfortable, two external pockets provided a useful space but not super large, and a larger internal pocket with velco closure was handy. The lowest temp we saw on the trip was 18deg and I did'nt need to add any additional layers, having the sun out helped and riding slower because we where on mountain passes potentially helped, at motorway speeds an extra layer may have been required. Out of Folkstone it was 22, windy and cloudy, i'd say this was on the edge of OK. The highest temp was 38deg and it was warm but I think anything waould have been with the exception of losing the jacket altogher and riding in a long sleeve top which I was'nt prepared to do. For reference i'm 6'3" and 40" chest, jacket did not feel short in length or arms.
