Comfortable, Flexible, and a Worthwhile Safety Upg

Fits perfectly in my Alpinestars Halo jacket. The flexible, rubbery material moves with your body, making it much more comfortable than the standard insert. It’s a solid upgrade in both protection and fit—no bulk, no restriction, just better peace of mind on the road.

Bought this version to fit Ixon jacket after in store helped find armour that fit pocket. This version was the cheapest at the time since all D3O is the same, you pay for brand name on stone for no reason so shop round

Bought this to fit into a recent jacket that I bought. I have a number of jackets, which all now have D30 back protectors in, and would highly recommend them for comfort and they do not make you sweat on hot days.

I already have one in another jacket and had been swapping it but for the price it was worth it, a lot lighter than the one that came in the RST jacket and the usual Sportsbikeshop service

I have a really old jacket from my youth, I don't want to throw it away it's been with my so long.
I treated it to new shoulder, elbow and back ptotection but it only takes a very small back protector and this fits perfectly. I barely know it's there.

Lots of ventilation holes and protector is very flexible. Just a little heavy on the XL sizes but good coverage.

What’s not to like, light weight, not bulky, and due to there design doesn’t make you sweat in warm weather. Hope I never have to test them out, but they do feel quality at a reasonable price, ordering and delivery was the usual hassle free service that I have come to rely on by Sportsbikeshop, and have now fitted these in all my jackets.

Hope I dont find out if it works

5 stars is a guess to its efficacy. But based on a solid but pliable feel and a good fit to my large Held jacket. It moves with you.

Whilst not the thinnest of back protectors, it is very flexible so moulds to your profile easily and comfortably, which I was not expecting for a CE2 protector. I'll just need to lose some of my Christmas weight to gain a bit more space in my jacket!! Staff in Bristol were excellent giving advice, and fitting into my jacket!

Just about squeezes into my Dainese Jacket which should have one as standard. Light and form fitting so doesn't feel like an ironing board down your back.
