The positives:Surprising an outdoor outfitter company designed this to fit a person larger than a shirt size medium, weighing more than 160 pounds. I'm a big guy, even when completely thin, I'm a big guy, but I'm a bit overweight at the moment and am working on shedding the last of the weight and am taking long hikes and running and needed a hydration pack for that reason. This not only fits me (I'm not just a little overweight, I'm a weightlifter), it has room to spare so it'll easily fit a person upwards to around 300 pounds I'd dare to say.The negative:The pocket is absolutely worthless. When I check to see if it had a storage pocket, I was hoping it would fit my S25 Ultra because I use Bluetooth and listen to music when I hike or run. The only phone that would fit in this lousy pocket would be an old 2002 Nokia flip phone. It's basically made for a car key and a think wallet, nothing more. I have to put my phone in with the hydration bladder. Camelbak wasn't thinking at all on this one.Also, I wish it had a larger capacity for water. The hydration bladder is only 1.5L, but I knew that when I bought it and when I'm using it, it's around town. I wouldn't recommend this anywhere else where hydration will really matter.

Nice product, very comfortable in use, with great storage for its size. Its hydration bladder was smaller than expected, but its capacity was clearly stated in the description.

I would gove this a 4.75 out of 5 if I could. Received this item over the past weel and on the weekened, tested it out on a 17 mile Urban hike (with partial jogging) from Virginia into D.C. for some sightseeing. Camelbak is a namebrand that has been around since before my Marine Corps days. In fact, the Marine Corps issued Camelbacks back in 2006 and I STILL have that one...so the quality they are known for is present in this model.These are my very small but present exceptions. The volume of water is intentionally small (50oz which is almost 1.5 liters), not bad although likely not intended for an 8-hour urban hike, so consider your particular water-intake needs vs what you want to tackle. I think I overdid it.#2 the zipper compartment on the bottom is very small....but with the bladder filled, it becomes even tighter. With the bladder full, I was able to squeeze one key+fob, a debit card, 4 Tums tablets in a sandwich bag, a 41/2" Mophie battery cell (which is not small) to recharge my cell phone (which I carried in my hand), AND a coiled 3.5 foot cable...so come to think of it, I squeezed a LOT in there....which made me go test an iPhone10 in there as I was writing this review. Nope, iPhone10 will not fit, even with an empty bladder, but that's still not bad.#3 the way the straps are shaped under the arm pits and how they connect to the pack kind of makes the entire pack ride up a bit on your upper back, which aesthetically can make you feel like you look a little awkward with this tiny turtle bump on your upper back. If you dont care so much about appearance, then it's not an issue. As I emptied the bladder, the pack seemed to relax down more.Otherwise, this pack fits REALLY snug, which is what you want when you are jogging/hiking. Once you buckled the chest buckle, the bounce of a full bladder while jogging is quite minimal, even for 1/5 liters. The flap that comes over the bladder mouth is very secure and the easy fill access to the cap is a godsend, I am still testing for cap leaks, not 100% sure yet.

I have bought several of these over past 10 yrs and because the Amazon " price was right" I decided on this one. Must admit, design improvements such as much larger fill hole, much improved locking system ( so NO LEAKS), minimalist feel and bite valve at correct height ( even though I switched tube to left side) it still came out perfect. Since there are always many questions...I will answer in advance. Small pocket (see pic 4) only big enough for keys...50 ounces of water is plenty..it weighs practically nothing, fits in the small of your back and you don't even feel it. Water does NOT taste plasticky whatsoever. You can even put ice in it..then add yr. water..and it stays cold for a long time. Just an excellent product with unbeatable value.

i bought this to use in the tree service industry for climbing up trees. it holds 1.5L of water and its enough to keep you going for the time in the tree. it can be a hot one up there so wearing this on my back helps. even has a small zipper pouch for smaller treats you can add. i will reccomend this to anyone using it for work or running, super light and reliable. no issues.
