I received my Alpinestar A-1 Roost Deflector close to 2 weeks ago, and have only wore it around the house!, in the middle of doing a rebuild on my bike and waiting for some parts. also, with the emergence of the Coronavirus in our area, most riding areas at this time are off limits...will have to wait till life gets back to some kind of normalcy before I can give it a test run.
Wanted lightweight protection for under jersey use and this is perfect. Just wore it during 2hour harescramble and forgot I was wearing it. The extra foam edges give a lot more coverage than the original A1.
I have worn the original A1 for a while now and this new version is a ton better. More roost protection on the front with the added foam and wider shoulders. The back is more protective as well. Being a taller rider the shoulder straps have more length and I can get it to sit where I want.
