The Razor 18 is a new breed of packs, packs that protect against the harshest conditions and the hardest terrain!
The integrated Shield Back system incorporates body armor with a traditional backpack Features: Fleece lined goggle pocket, front panel access with interior probe pocket, dual front stash pockets that can be accessed on a lift, ski and snowboard attachments, two ice axe loops, padded waist belt with pocket, mesh helmet holder, and a sternum strap whistle
Fantastic!!!!! Both packs fit fantastically. They pack easily and hold a good amount of equipment. The back cushioning system offers a lot of protection in the event of a fall. I took a bad fall with the 23 and I was well protected. I highly recommend the packs for hiking and the 18 for mountain biking.
