So I bought this product for my summer mesh jacket which is also alpine stars. Back of this mess jacket is basically completely see-through so I felt unsafe riding without some sort of protection. The jacket has a slot that this fits right into. Just double check the size so my jacket is a medium and it fitted the medium pad. But you can find the measurements for the pads on here and then just measure the opening inside your jacket. You can tell by feeling it that it would definitely protect you in a slide, but it's also very comfortable like it. Just flexes to your back. Very impressed with the alpine style stuff

Look, if you buy a jacket without a back protector, then get one of these.

Fits nicely into my jacket and feels soft enough to ride comfortably but also robust enough to do the job it was designed to do.

Get one, you won't regret it and you will thank me, god forbid, should the worst happen.

This size L armour is the perfect fit for the Alpinestars halo jacket size XL. Good coverage but obviously doesn’t extend to coccyx but found I wasn’t wearing my separate back protector anyways. Bendy but breathable
