My brother's review on this pack:
This backpack was excellent for travelling and gear storage. I took a trip to Greece specifically to climb. I used only this bag and I was able to pack all my clothes and toiletries in the bottom compartment, a first aid kit, multi tools, head lamps, and a couple books in the top compartment and a full rack of quick draws, alpine draws, 6 lockers, two belay devices, two harnesses, two pairs of climbing shoes, a 50 ft and a 20 ft accessory cord, 50 ft of webbing, a set of nuts, a set of tri-cams, a separate day pack, a 1.5 liter Nalgene and an 80 meter rope in the main compartment. I am a savvy packer and was amazed at how much I could fit in this thing. There was even a small amount of room left in each compartment. It had a separate side compartment to store all the straps in when checking the bag which was nice because I������ve had buckles broken and straps torn in the past after checking a backpack. Every time I got the bag at baggage claim there were there were new scuffs and scratches but it never wore through the material and nothing ever broke on the bag. It has a ton of gear loops too which made gear organization super easy. The only negative feedback I have is that it doesn������t have any sort of frame. It still wasn������t too bad to wear around for a few hours at a time. Sizing is easily adjustable to share between users.
