Osprey  Rev 6 Hydration Pack - 1.5 Liters

I just bought this to support myself on my long runs. First outing: 26 mile trail run with about 4000 feet in elevation gain. I was nervous taking it on such a long distance not having tested it on anything shorter, but it performed perfectly. The bladder lasted me until about mile 21, but then I just refilled at a stream. Unfortunately, the iodide purification tablet stained the bladder, but I guess that's to be expected. Pros: -It doesn't slosh too much. -It fits great, and has the right amount of straps so you can adjust the fit as needed. -I experienced zero chafing (I wore a shirt under it). -It carried everything I needed for my run and it still had room for more. -It's got plenty of pockets so I could keep my stuff organized. -I really like the magnetic mouthpiece holder. Con: -It gets dirty easily. Overall: Definitely recommend.

I purchased this pack for mountain biking because normal-sized packs are too big for my body. It works great for that purpose (even though it's a running pack)--it's very comfortable and holds the right amount of water 2-4 hour rides. But I can't get the nasty plastic taste out of the bladder so I'll probably return it. Too bad. Also, it has a special cell phone case but my iPhone 6s kept falling out of it so it's a cool feature that ended up being kind of useless.

I use this mainly for road cycling on long rides. The size is good and doesn't interfere with my jersey pockets. The magnet on the mouthpiece is a nice feature as well. The shoulder straps are comfortable and don't chafe or otherwise bother me, and it's nice to have a little extra storage in the zipper compartment. My only complaint is that there's a noticeable plastic taste that doesn't want to go away. Other than that I'm pretty pleased with this product.

Great for trail running and music festivals. I actually use my camelbak 3L bladder in this osprey pack and it fits real well. The only thing I compromise is the magnetic tube feature, but I just stuff the bite valve into the one of the front pockets for easy access. When I hit the trails I also pack a sandwich for long trips, snacks, sunscreen (travel tube), buff, car key, ID, extra shirt, multi tool, phone (iPhone 6 Plus), earphones, and I still have lots of space left. I could theoretically add two water bottles in side pockets on the pack, probably add a rain/wind shell, and still have lots of space. The water stays cool. With all that weight the pack is still comfortable. I've run with that weight in the pack and worn the pack shirtless hoping it would be comfortable and I wouldn't chafe and to my surprise it was very comfy and no chaffing at all. I swear a lot and the pack isn't the best ventilation but it wasn't until I took the pack off that I felt uncomfortable. The material wicks so the pack drys faster than your sweaty body will. Overall great pack for price. I paid approx 75 for it when it was on sale. Worth every penny!

This pack is great and has already been a great help on several long runs. I love that the hydration system is so easy to fill up- the detachable hose makes a HUGE difference in both fill-up and cleanup time. I was a bit skeptical of the fit since it doesn't have a waist strap, but it stays in place and does not flop around, and not having a waist strap is so liberating! It has a zillion pockets, which is always nice. My only two "areas for improvement" would be: 1- Make one of the front/accessible pockets a bit more secure so that there is easy access to essentials- I lost a whole sleeve of Clif Bloks from the front storage without even noticing it... So now I keep nutrition in the zipper pockets, which means to access it I have to stop my run and take off the pack. 2- A bigger hydration pack would be useful, but that's just personal preference, I suppose. My prior bag had 2.0L of hydration, which is really useful on these 90+ degree days with 90% humidity we have been having. I think if I were to buy the 2.0L bag separately, it would fit, though. (But won't be testing this anytime soon since the weather is finally cooling down.)

The right combination of water and clothing capacity for longer trail runs. Most importantly, pockets on the front straps hold the phone and food so I don't have to stop. Important to note the sizing, I bought the S/M one first and had to return it for the M/L version.

I recently completed the Salmon Falls 50k trail run near Sacramento, CA. Some may consider this pack overkill for a 50k, but I am training for longer, unsupported races. With 1.5 liters of fluid capacity, I never ran out of water between aid stations. The pack has just the right amount of storage for my fuel/food, first aid, jacket, extra socks, light, hygiene, etc. It's so comfortable that I wear it on nearly all of my runs. The cellphone storage pouch and other shoulder pockets are perfect for small items and quick access. I'll be looking for the REV24 soon...

I spent a lot of time looking for a small day pack that still had high-quality features (not just a sack with shoulder straps), and this is THE WINNER! Just came back today from a 10-mile day hike and love it in action just as much as at the store. Pluses: Smaller than most technical day packs for great mobility; AWESOME easy-access pocket on the left should strap, sized for a camera or phone (clever design also allows you to tuck your phone/camera under main pocket to what seems to be a water-tight sleeve beneath in case of rain); Another great expandable easy-access pocket on the right shoulder strap for a map, sunglasses, etc; 2 elasticized chest straps that adjust up or down on the shoulder straps; Side pockets that wrap toward the front enough that you can actually reach into them while the pack is on; great ventilation/breathability on the back panel; Surprising capacity for your stuff with 1 large compartment for the reservoir sleeve, another large compartment, 1 small with key clip, and the elastic on the back that cinches across extra clothing; High-quality zippers that don't catch on the fabric. Minuses: It's slightly short for me (I'm a 5'8" woman) so even adjusting the bottom chest strap to the lowest position rides a little higher than I would like; at 1.5 liters, the reservoir is a little small, but my 2.5 liter sleeve from another pack actually fits the compartment so this can be swapped out for longer/hotter hikes.

I bought this to stuff extra layers in. The pack fit well when empty. However, when full, it hit my chest in an uncomfortable way, especially because the straps were thicker/stiffer than some (e.g., Ultimate Direction). I have to say, though, that I didn't test all the side strap combinations. I'm female, 5'4".

I bought this a month ago and have hiked with it about six times now. It is light weight and the hydroflask is great! Easier to clean the others and the quick connect feature on the hose system is great for filling and emptying. It is very small, I can get water, lunch, a spare pair of socks, and a small first aid kit: Great for the day, but not much more will fit in there. The drawstring system on the outside allows me to tuck a rain jacket in there if necessary.
