I’ve been using the Mavic
"I’ve been using the Mavic Cosmic Wind SL jacket for a while now. If you're looking at this, keep in mind it is a true "race" fit. I’m a bigger guy, and it’s definitely snug on me, so if you prefer a looser feel or want to layer up heavily underneath, you might find it restrictive. That said, it does exactly what it’s supposed to do. It blocks the wind effectively and handles light to medium rain without issue. I’ve been caught in a few showers, and it kept me dry enough to finish the ride comfortably. The drop tail is a good length, so it covers your back well when you're in the drops. The best part for me is how small it packs down; it takes up almost no space in a jersey pocket, which makes it an easy piece to carry just in case the weather turns. It’s a solid, functional layer if you don't mind a tighter cut."
