[ This was with me for a week long backpacking trip. It held ample water even with the baffles in place to allow it to fit my pack's water reservoir sleeve better. This thing never leaked on me and paired nicely with my Sawyer mini and the hanging system in my pack. It was easy to fill with water in a few swift scoops and locked up nicely after filling. The only thing to be cautious of is avoiding any sort of air/water locks in it by filling it up before it gets totally drained.

I spend a lot of time in the backcountry and had to make an emergency purchase of the shape shift 3L at a local store after my older one( different company) started leaking. I really like that it has baffles that helps with the sloshing around when it ’s not all the way full, or that you can open up the baffles to allow even more water into the reservoir. Plus I am thrilled that you can turn it inside out and stick it on the top rack of the dishwasher for easy cleaning. Unfortunately, my very first time taking it out on the mountain mine developed a hole at the top of the reservoir. I don ’ t know if this way due to it having a pressure point by the way it sat in my pack, me setting my pack down to roughly, or a manufacturer defect. Regardless, I filled out the warranty claim( I figured it was worth a shot) and within 24hrs I had a response letting me know my claim was accepted, and within 48hrs I had a new reservoir being shipped to me. Great customer service speaks volumes to me, and they went above and beyond what most companies are willing to do! Now with all that being said the Shape Shift was the only 3L one in the store with no other options, and I was leaving that day for a trip so I was desperate. After seeing all of Hydrapak ’s other products I think the HydraSleeve 3L would be a better all around option for me.

Perfect hydration bladder for a range of running distances and activities. Like the ability to reduce and have stability for the medium volume runs and then full open for those peak distances. Fully reversible for cleaning is a must.

[ Very durable and has lots of storage. I got the extra armor padding as protection. It has a tight fit with wafer filled all the way. The bladder system easily detaches at the drinking tube which is convenient

[ 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 was gifted this bag in 2009 and it just ripped slightly on top in 2024. I was n't even sure the brand, but I had to look it up and give a review because 15 years of monthly hiking use on a bag is really impressive. Needless to say, I 'll be buying another!

Hikerboy
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!

[ 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 have had my Platypus Hoser for more than 15 years now and it still works great. It's the two liter version, very similar to this one. No complaints ever, easy to clean, light weight, and very durable. My version even has `` patent pending '' still on it. And a logo with a Platypus illustration, which I love! Thanks@ Platypus for all these years of joyful and well- hydrated hiking and biking thanks to the Hoser:)

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.
