Verified Customer Reviews for Knox Micro-Lock Compact Back Protector Upgrade
Great alternative to Rukka 
03 Aug 2026 by Tim
Bought this as a cheaper alternative to the largest Rukka back protector to go in their Kalix 3 jacket (size 60). Expected to have to trim it down but amazingly it fits perfectly despite the dimensions suggesting otherwise. Appears to offer the same protection so I'm very happy!
