The breathable bit is all about what happens when you stop working hard, stop riding and cool down. Non-breathable fabrics will leave you in a cold bucket of sweat, at risk of hypothermia on a cold day. Breathable fabrics allow you to dry out when you stop cycling/running/walking
BTW, if it's warm enough to be wearing short sleeves it's probably too warm to bother with a rainjacket - just get wet, and dry out when the rain stops. Breathable fabrics all work poorly against bare skin; much better when there is a wickng layer of clothing underneath them.
So, maybe reassess what you are expecting from a jacket.
Thanks for clearing that up. I really did think that breathable meant that it allowed sweat to evaporate off you and out the jacket without making you uncomfortable (doh). Maybe (unless it is cold) a lightweight top that can be swapped out when it does stop raining (assuming heat does not dry it)?
I was thinking I was just getting dodgy jackets and it took me all this time to have someone point me in the right direction ... thanks
