Great ptoduct

L and XL are same in size!, only the waist straps differ in length. I went with L, because the XL straps were a way too long. It makes my old Alpinestars back protector look useless. Very happy with the upgrade.

Great fit

Very impressed with this product, holds close to the spine. The waist band allows to keep snug and stop moving.

Contours perfectly

I reviewed a number of back protectors before settling on this one. CE LEVEL 2 which is better than 1 and offers lower levels of energy transfer which is what you want. It contours perfectly with you're back and after you've had it on for a few minutes you forget it's even there. Goes perfectly with the KRC and you can attach the straps to have a complete chest and back protection unit. Delivery timings excellent.

Spot on product

Bought this product and read other reviews. I'm 6 Ft so went for the large size. Fits a treat and is unobtrusive. I got used to it immediately and it's reassuring to wear. You never know do you! Would recommend.

Lightweight and comfortable

I've tried a few back protectors with no major complaints but the KR-1 is outstanding its light very comfortable and unobtrusive to wear under my leathers. I am exactly 6 ft tall and fall in between the medium and large sizes on the size guide so ordered the medium but it felt too short and didn't give me the cover I wanted so I exchanged for a large size and got the perfect fit. I couldn't be happier with the service from Sportsbikeshop, they've been very helpful and extremely quick.
