Giro’s Wind jacket pulls together really impressive windproofing with top packability thanks to its use of Rip Stop Nylon. It also manages to offer decent ventilation, and the question is really whether you can justify spending £80 on it which is a little steep for a lightweight jacket that’s not totally waterproof.
At this end of the year it’s pretty important to have a jacket that you can store in a rear pocket and taken out should things turn nasty while you’re out riding. So the first thing to look at on a jacket like this is ease of packing, and how small a space you can stow fit it in.
And against this criterion, the Giro Wind jacket scores very well. It packs down very small and easily gets into a jersey pocket. I even managed to fit it in my saddlebag alongside my emergency puncture repair kit, which is extremely impressive. Part of the reason it manages this is because it packs into a bag built into the jacket itself that can be packed away and makes sure it stays small in your pocket.
