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

It fits perfectly under my jacket and moves naturally with my body, making it easy to wear even on long rides. For the quality and safety it provides, it’s a fantastic value.

This is definitely made from good material and feels like it could withstand the impact. It's flexible enough to get used to it and slots in perfectly with all 3 of my alphinestars jackets.
