The M15 formula gives a shock absorption material with outstanding performance characteristics. It's light, elastic, it has slow recovery and is robust. The ideal impact absorbing material is one that on impact compresses to a degree but then slowly returns to its original shape and size. So the better the material the longer this moment is delayed. M15 slows the moment of peak transmitted force and spreads the damaging forces over the whole surface which means that the material is used to its maximum. Combination of M15 and multi-layer construction results in a system that is both lightweight and flexible.


Small sized insert fits R15 backpacks
Medium sized insert fits R20, R25 R30 and R35 backpacks
Protector is simply inserted in to be back panel sleeve to fix it in place.

not tested.......
Bought this to fit inside the back pack i'd bought. So can't really comment, because fortunately it hasn't been tested!! Looks good and fits perfectly.

Not tested ... yet
Only giving this 4 stars as I have not had the dubious pleasure of testing out it's effectiveness yet. Fits perfectly into my trusty R35 and does not take up much space at all (or add much weight). Good product as always and reassuring to have it in place.

Fitted in R25 OK
Bought medium protector which fitted inside R25 nicely. If it were the honeycomb material from Forcefield it might inspire more confidence, but I'm sure it's better than nothing.
Kriega replies: Hi Peter, Thanks for the comments however the M15 foam we use is the lightest level-2 armour Forcefield make which is equal to the honeycomb in protection.
