Good fit for my Segura jacket. Hopefully does the job if required. Excellent service from SBS substituting this product in when the Segura product was out of stock.

Great protector

A great bit of kit that fits my merlin hoody perfectly. I knocked a star off as it's not as flexible as the better microlock stuff but for the price, I'm very happy

Economical and good size

Bought it for Triumph summer jacket - fitted perfectly. Also tried it in other jackets and fits well - good universal size. Looks like good protection but obviously rather not try it.

Good protection

The back protector is not as flexible as it looks, and is approx. 23mm thick. In a slim fitting jacket like mine, it make for a tighter fit.

Seems the biz

Bought two of these. Comfortable, lightweight and fit perfectly in a size small Tuzo Dakar and Belstaff (forget model) jackets. Check pocket dimensions of your jacket before ordering. Looks like it could perform when really needed.

    Unfortunately we are not able to advise as we are not an Akito stockist. Apologies.

    No, the Knox Advance X Part 106 will not fit into an Oxford jacket, you will require an Oxford specific back protector.
