Solid, but attention to detail counts
I have one of the earlier versions of this pack but as near as I can tell TNF has kept most things the same. The suspension is solid and it comfortably carries 50+ lbs. The hip-belt is sturdy and feels good all day. TNF has added dual hip-belt pockets, which we all love.
Overall I am glad to have this pack and find myself taking it out for all kinds of trips quite often. However, some of the attention to detail is lacking. I've had about half the zipper pulls pull apart because the string was melded into the plastic instead of running through it. As well, the zipper on the lid of the pack has slowly destroyed itself and no longer closes. I've replaced zipper pulls and will have a new zipper sewn in, but annoying when the little things don't work.
