Such a good bag, 100 oz of water is 4x my large yeti and the bag still has so much room I fit in an additional shoulder bag, snacks, some accessories and some green, and still had the half of the largest pouch not taken up by the water pouch. Bag is comfortable and stylish. Reservoir for water is incredibly well thought out and comes apart easily and in enough places that making sure the pack is dry after use is a breeze. Nice quality straps, small footprint and breathable materials means your back isn ’ t burning up. I ’ d say if you ’ re looking for a pack that will last you a long time and hold up as well as serve you well for carrying most if not all of the things you ’ ll need for 1/2 day hikes, you will be incredibly happy with this bag!

I purchased this last spring for my motorcycle trip from Spring Branch, TX up to the Arctic Circle in Alaska and back. It performed flawlessly for the whole 31 days and 11, 525 miles on the back of my MoskoMoto panniers. The little dispensing valve was great, as I could refill small water bottles, brush teeth, splash face and wash hands, wash/rinse dishes, mix cocktails, etc., all right from the bag holder on the back of my bike. I am very happy with the bag and always pleased with MSR products and their Customer Service Dept.

Bought and used on multiday backpack. Overall worked perfectly for what we needed. Con: the elastic tie on one end is not load bearing. Pro: a full bag survived a 6 foot fall onto sharp rocks; no damage at all. The packaging could use directions or link or something with initial cleaning directions. I found them online and no plastic or strange taste at all.

[ I purchased this for a two day camping trip and it was my only water source. I didn ’ t bring any sports bottles since my frame bag took up the whole space. The backpack has a lot of nice features( sunglass pouch, key ring, and several side pockets) I especially liked the magnetic clip for the straw. I also used the helmet clips to hold my helmet when not in use. The only thing I think it was missing was a cover for the whole thing just in case it started to rain while you ’ re on a ride. I was afraid I was going to have back pain from all the weight but it was well balanced. I ’ m very impressed!

I ’ ve had the pack for over a month, works really well for longer trail rides. I am able to carry a pump, extra tube, multi tool as well as an energy bar, keys and smart phone without the pack seeming over loaded or bulky. Traditionally not a fan of riding with packs but this works so well and is great for staying hydrated. Unexpected bonus is my helmet easily clips to the pack when done riding allowing for easier storage. Only difficulty has been filling the bladder, but after a few tries I ’ m not spilling water.

[ Hydro pack is awesome for the money. It has the straps of the high end packs and the venting of the highbend packs for less money. Literally like wearing nothing. I pack 2 meals, a small burner and change of clothes and everything fits perfect. Not to mention the 2L bladder. Very comfortable, little to zero bounce on MTB trails. I even jumoed a few times with it and forgot I had it on. Great bag!!

[ I bought this to supplement some of my cycling adventures, which include long distance gravel and MTB events. Sometimes having the extra water on your body gives you a competitive advantage, sometimes it is just necessary to survive. All in all, you ca n't have enough water and snack, but this pack is small and tight enough to give you all you need and no more. Fits great, hassle free, and love it.

[ Bought this to replace a leaky bladder in my running pack made by another company. It does not leak! The zipper feature is nice; it clicks once it's fully closed. There is some structure so you can open the bladder with one hand, which makes filling it easier. It barely fits inside my pack, but it fits, phew.

[ Used it over the Labor Day weekend during a two day hike in the Shenandoah National Park. The new zipper and hose quick connect made every stage of the process so much easier. Refilling the reservoir without removing it from my backpack was a breeze. My son now wants this upgrade too. I already purchased one for him. We ’ re both looking forward to our next outing.

[ I have only used this for a week so far. I like the zipper more than the screw cap, and have not had any issues with leaks. The hose is VERY long though imo, so the mouth piece keeps getting covered in dirt. Having only used it for a week I wo n't be rating durability at this time

These do wear out with heavy usage and have to be replaced once they start the mysterious slow leak, in which water escapes into the backpack with no discernible source. I 'm glad to see the straw redesign because the plastic bent on the last one, which I did n't like. However, they 're great for hiking hydration in a light pack that keeps my hands free. Just purchased for the third time!

First one of these I have used. Couple of days to clear the plastic taste, then you are in good shape. Used this on a 5 day hike and it worked a treat.
