Castelli Leggero Vest: EXTREMELY LIGHTWEIGHT AND COMPACT. When you need protection from wind, cold, or rain, the best jacket is the one you have with you. So we made this one impossibly small and lightweight. And we made it windproof
Strengths: Very compact and lightweight
Mesh back is also hi viz.
Weaknesses: Seems delicate.
Probably will need to go up one size.
I had been looking for a very compact lightweight wind/rain vest to keep in my jersey pocket or saddle bag just in case. I required a mesh back to help control sweat. I got this on sale for $35. I take a medium jersey in Castelli and Capo, which fit me snugly. I got the large in this vest and it fits perfectly. It's a bit short in the front when standing erect but perfect on the bike. It's very lightweight and compact weighing 72 gm on my scale. I got the hi viz yellow and like that the back mesh is also hi viz. It comes with a little circular storage pouch for it, has no pockets, and has a two way zipper which is a nice feature. It is very lightweight and seems a bit delicate so go easy on it and the zipper. It works great in the dry but I have not ridden with it in the rain and I suspect it would offer very minimal protection.
