I have both the Airman jacket and trousers and without the goretex lining it lets plenty of cool air through. The jacket has a pouch on the back to carry the liner on a hot day if rain is forecast and only flaw I've found so far is that with the trousers you need to decide before you ride whether to use the liner or not....unless you don't mind fighting the liner at the side of the road in your undercrackers. I also have a pair of over trousers but that seems to defeat the object a bit. Oh and for the price Rukka are taking the piss by not including a back protector.
