The Kriega Back Protector Insert transforms your backpack into a protective shield. Designed with RHEON™ technology, its algorithmic cell structure mimics nature’s patterns for an ultra-light yet highly protective design. CE-approved to the highest level, it absorbs and dissipates impact energy without compromising flexibility or comfort. The dynamic material adapts to movement while providing reliable protection exactly where you need it. Simply slide it into your Kriega backpack for a “fit and forget” experience — lightweight, flexible, and ready for any ride. Compatible with all Kriega backpacks except the Hydro-2 Hydration Pack.
