The Ultimate Riding Jacket?

eVent is actually a very effective breathable fabric.

I moved from GoreTex PacLite to eVent recently. The PacLite would feel horrible and clammy very quickly on my commute and no amount of venting would help. I can now do my commute in eVent fully zipped up.

+1 for the Rab Momentum hardshell. It weighs 300g and is very breathable and completely waterproof. A great winter jacket. Best bit is the cut, I am 6' 3" and wear a medium, perfect length and snug on the chest and waist.

I too am 6' 3". I always have trouble with jackets being too short on the torso. Is the medium Rab Momentum long enough over your bum when cycling? I also have long torso / short legs though... What's your inside leg?
