This is a pretty cool bag.
It's light weight but tough. I use it for my climbing gear. I can carry my harness, chalk bag, two pairs of climbing shoes and still have a bit of room. I would really like if it had a daisy chain but that's just personal preference.
It's pretty comfortable, but since it's light weight material you can feel what's in your pack even with the pad in it.
I bought it during the Memorial Day sale so I got it cheap so it was more than worth it to me, even at its normal price I'd still have no regrets about having bought it.
