Great bag, heavily built and solid, not a thing to complain about.I've had a bunch of bags/packs, the majority were no name off brand ones. Many were garbage that began to fall apart within weeks to months. The last one I had before this was similar to the Condor brand 2 strap type that is the same size as this bag, I don't remember who made it. It's held up for about 3 years but that's with medium to light use and it's showing it's age.I thought it was a great bag and it is a good one for the price, I think I gave about $30 for it at the time. This bag though is much better in all aspects but price, however quality costs money. The 10 just shows what a good bag really is and until you actually get a hold of one in person you have no idea. The material is thicker, stitching is better, buckles are better and the zippers are amazingly great.The inner pockets are as tough as the outside, most cheap bags have thin pockets and the divider between compartments is thin as well. The pockets and organization in this bag is just laid out perfectly, everything just has a place to go. Is there room for improvement, sure, as everybody carries different things but this is the first bag that kept me from immediately thinking I needed an external pouch for something.I'm 5'6" and 140lbs, the bag carries comfortably and isn't too small or large. I have loaded it up to a weight of 25lbs. to see where it becomes uncomfortable. I'd say 25 is doable on a short trip but for hiking or long walking travel I'd say 15 is about max. This is reasonable as generally you shouldn't expect a bag that's over 10%-15% your body weight to be comfortable for long time frames. This of course depends on you fitness level and such, some may be more and others less.This bag can easily be over packed due to it's size and being a single strap can make it more uncomfortable quicker. If you're the type of person who carries a lot and it's heavier stuff, get a 2 strap. If you just carry minimal or light things, this is perfect. I mainly carry a small 1st aid kit, a book, notepad, chromebook and a hand gun. I do also have a few 'survival supplies but they are small and light.The main weight I carry is my son's supplies, he's 10 and special needs. I carry some diapers, wipes, spare clothing, feeding bag, couple of boxes of Peptamin JR (his formula). I may on occasion carry more if it's a overnight hospital stay, mainly supplies for me. It holds all this plus has plenty of room for more and considering I'm not doing a lot of walking, I don't see the single strap as bad.I'm happy with my choice as a long trip or overnight bag. I will say for short trips and such, I'll still carry my Maxpedition Remora more often and that's due to size, it fits nicely on his wheel chair. Then again the 10 may become my me bag and the Remora more of his bag. In our situation one small and one medium bag is much easier to manage than one large bag, as they drag on the wheels of his chair.This is a great edc, camping and duty bag, It would also make a great diaper bag for those who want something a little different, especially since it holds a hydration bladder. It is high at $100 but honestly worth the price in my opinion just based on the quality of what you receive.
