Ok, this is more of a survivalist type pack, but, it is burly and it's a panel loader design. This would make a good "bug out" or hunting pack.
This pack has a great amount of storage and it is hydration compatible. It has heavy duty packcloth, webbing straps and buckles. It has a waistbelt with zippered pockets attached. It also has a zippered expander to increase the pack's volume. All zippers have cord and toggles attached to allow opening while wearing gloves. Front pocket is an organizer pocket w/key keeper, second pocket has stretch mesh inner and the main compartment has buckles and straps for keeping items from shifting. There is also MOLLE webbing on the exterior for even more customizing and one exterior mesh pocket w/drawcord for a water bottle. I purchased this pack new and have used it lightly, mostly as carry-on on air travel. ACU digital camo. Took it on a dove hunting once also (no doves were harmed, that day). This pack would be considered "frameless". I can provide more pics on request.
