Product Reviews


martin brunsden: great

great soft protector...using it in the Naren jacket and dont know its there...recommended

Geoff: Not noticed on the bike

Really settles into the back well, especially with a little warming up and just not noticed in day to day riding. Bought as an upgrade to existing armour in an aging, but favourite summer jacket. Warm weather incoming.

Lynn: Fit and Forget

Size S for my BMW leather jacket. Fits the back pocket perfectly. Comfortable and unobtrusive.

Mark: Great fit for Halvarssons

Got two of these on the back of top notch advice from Steve. Size L fitted size 38 and size 52 Halvarsson jackets perfectly. Really unobtrusive too.

Paul Dale: Mr

Fits my Halvarsons jacket perfectly. Unobtrusive and comfortable.

Crispin James: Mr

Happily not used in anger as yet but fits in the Belstaff Crosby very easily and is unobtrusive when fitted - you know it's there but it is by no means uncomfortable. There are a lot more jacket sizes than back protector sizes. I used a medium back protector in an XL Crosby and a friend used the same in an XXL.

Thanks for the review. Glad it fits in the Belstaff Crosby.
