Not holding up

I've used it several times

I bought this pack for longer day hikes and I have to say I'm very disappointed. Loaded with 3L of water and some gear this pack is very uncomfortable on my shoulders and little things started breaking after the first hike I did with it. If you're looking for a bag to drag up and down mountains this is not the one. Also the blue in the photo is wayyyy brighter and lighter than the actual pack.

My Go To Pack!

I've put it through the wringer

This pack rocks. I have an 18L osprey and a Gregory 28 liter. I have used several packs over the years and before I head out to summit a peak or set out on a day trip.. this is the pack I reach for every time. Just the right about if external pockets, features etc. I truly love this pack. So much so, that I must say it’s my favorite peace of gear. Seriously give this pack a try, it does it all!!

Perfect 20L bag

I've used it several times

I was having a hard time finding a smaller pack that will meet all my needs for those shorter day hikes or small adventures, but here it is! The awesome external pocket makes it easy to stuff layers in and allow them to be accessed quickly, without having to pull on the contents out of your pack. The side mesh pockets are HUGE and make it easy to tuck a nalgene in or even some rain gear. When empty it lays pretty flat and will easily sit on the bottom of a suitcase or duffel bag to pack away for you next trip when you don't want to use this bag as a carry on.
