Good for Rukka

Big soft and flexible. Better than the previous Knox back armour I already owned and that was only Level 1 protection. It fits well in the pocket of my Rukka Forsair Pro. Seems comfortable though I have only worn it in the house. I have only given four stars cos there is no hanging tag on this new version of the armour to attach to the velcro at the top of the pocket. The old armour has one. So I have put some string through two gaps in the armour and then it can be held correctly and float in the pocket. Overall recommended.

Very good back protector

It is breathable that is very important for hot Greek summers, comfortable and steady. It came quickly and the communication with the shop was perfect.

Certainly looks the part and was the back protector reccomended by the jacket manufacturer. Comfortable and unobtrusive when fitted in the jacket. Thankfully I've not had to test it but have no reason to doubt it'll do the job.

Nice and soft

Bought this to replace the one that my Triumph Navigator jacket came with as it was the hard cheap kind that makes your back sweat even in cold weather, and it gave you no freedom of movement. This product is heavier but breathes and feels much cooler it's also very supple I am well pleased with it, It was easy to fit, I but it in the jacket and sent off on a long weekend 532 miles by the time I got back, and can honesty say I had not felt it at all, and no nasty wet back.

Astounding product

I come from an era when you had one choice in back protectors - hard as rock and took an age to break in. The Knox Micro Lock Back Protector is fantastic. Its like being hugged by a very large marshmallow. A marshmallow which incorporates the latest technology, makes you feel very safe, and lets your back breath. A big thank you to Knox.
