Familiarity: I've used it several times
This pack fits perfectly. It is adjustable enough that it can be comfortably positioned low on the hips or high on the waist. The perfect fit also prevents the pack from slipping around you or twisting.
I've been looking for the perfect lumbar pack to take mountain biking and this is not it. It's the closest that I've found, and it might sound absurd, but it actually has too much storage capacity. I realize that this pack was not designed for cycling, so I can't actually fault it, because none of my gripes would apply if I were hiking. If I wanted this much storage for cycling, I'd use a back pack.
I appreciate that the main pockets are very compressible and I really like the side pouches for quick access items. The pack really is a treat to use, I just don't need the extra water bottle spot and could do with a main pocket half the size. If that meant the bottle could be angled a bit more for easier access on the bike, I don't think I would be able to fault it.
