Likes:-the zippered pocket on the shoulder strap actually fits my giant phone with a case!- two 500 ml bottles can fit on the shoulder pouches, one on each- fits really well with the running vest style-side pocket can easily fit 1.5L bottles, one each, they're long and deep.- inside pocket in main compartment- back mesh pocket is huge, totally runs the length of the bag; covers so nothing falls off or falls in-has two ice are holders, you can probably store hiking poles there instead.- stow and hold pole holders, in case you're using hiking poles and have to quickly ditch them so you can climb a tree or a rock.Cons:-has bladder holder, but probably only good for 1.5L or less. Since I hate bladders, doesn't affect me. I can probably stick something else there quickly.- there's two hip pockets, but only one is zipped. The other one is open and shallow. I can't think of anything that I'd put there. Whatever you put there, should be tethered down, because you'll probably lose it.- the main pocket cinch strap, should be a little longer, to be able to fold down at least once. Otherwise you have a small opening, facing upward. It does have the large mesh covering it, but rain might go right in it.-a little heavy for just a 20 L- shoulder straps don't have a lot of cushion, so I wouldn't put too much weight on it, but remember to use hip belt. Most of the weight should rest there.-missing the helmet holder that the original talon has. I destroyed my climbing helmet just hanging, with a different pack that also didn't have a holder.-durability... I love the side mesh pockets and the back, but I don't think they will last long. We'll see.- need instructions on some features, not everyone will know how some of the features works. YouTube and Google doesn't always cover everything.Overall:I own about 25 packs now... 6L to 100L.Great design it's probably going to be my go to day pack.I went on a fast hike with it the day I got it, barely felt any weight. Everything is cinched down, so when I jogged, nothing was bouncing around.
