10/10 would recommend. Great fit and stays comfortable throughout longer runs

I ’ m training for a marathon and bought this because I kept running out of water and storage space for my gels etc. This vest is perfect. It ’s super light, dries quickly, has tons of pockets, and also carries enough water for those longer runs in the summer. Best purchase I ’ ve made!

5 janetflx_1768
[ This was very comfortable to wear while running. Does not feel heavy surprised it would feel heavy with water in it but no. Very easy to use and love it a lot

5 isxuh_9301
[ Decent sized hydration pack and is perfect if you love going out on hikes, bike rides, and even fishing. It ’s a good quality material and i noticed zero leaking throughout the few times Ive used this. Also an easy clean!

I bought this as a Christmas gift for my son who loves to trail run. Sorry I can ’ t comment more but he was really excited to get it. The bright red color makes for great visibility.

5 Amateur runner
I am a female with 5 ft 3 ''( 160 cm) tall and chubby, the vest( XS- M Size) fits me perfectly. No chafing, very light, not shaking when running, and breathable. Even it is advertised for men, but it seems to work well for women with my size. But I do n't think it would work for women with large bust.

5 Jon_
This is the only hydration vest that fits my 45 inch, that alone makes this perfect. I carry as much as two Bobo bars, three SIS gels, two 20oz flasks in the front pockets, one 14 oz flask, a packable rain coat and emergency kit. I could likely fit more atop that. Wonderful vest!

5 Rooskie
Great for long distance runnning! Very happy with my purchase!

5 RunRobRun
I purchased this pack about a month ago and it taking it on various hiking/trail running adventures. The storage is optimal for day use but you can also stretch it for a little longer. The value and quality of this product are top notch and a highly recommended. Even for a big guy my size it still fits perfectly.

I grabbed this for cycling, but brought it this weekend on a trip to Red River Gorge. Brought it along on Saturday when we did an 11 mile hike in 90 degree heat and this thing saved the day. Enough water to keep both my fiancé and me moving. Without ice the water stayed cool for hours. Fit is super comfortable. Holds a ton of food, gear, and water. Build quality seems good. Great pack for the price. Really happy with the purchase.

5 StarTrailer
This pack survived a week long bike trip from Cumberland, MD to Washington, DC AND a week's worth of daily abuse at Boy Scout Camp. It cleaned up nicely at the end and was no worse for the wear, a testament to Camelback's quality.

Both this for a hiking trip and it worked perfect 😍

5 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!

5 Sergfp
Saw this item in store and I immediately knew I had to buy it. I wanted a 3L camelback that was small and had pockets. This fit the picture perfectly. No leak issues, small and light. Had enough water for a good hike. It is pricey at 90$ but I felt more comfortable buying this after getting sketched out by Amazon reviews on other products.

5 Day Trippee
Nice size for my 9 year old son. He used it on our trip and the water capacity is large enough so that he never was thirsty on our hikes. Only drawback is that the pack does get heavy when all the water was filled. But the pockets and compartments make it easy to store snacks and some lightweight layers to increase its utility purpose.

5 shabeck
I switched to CamelBak brand because buying a new bladder was almost the same cost as buying a whole new pack. Absolutely worth it! Great amount of pockets and the bladder is much more user friendly than my previous pack as well.

[ This pack made all the difference! Beyond happy with my pro deal sponsorship. I have been using a cheap and poor fitted pack for years and I never realized how big of a difference this would make for my work.

As a Boy Scout this is very useful for scouts and other outside activities.

Completed the Everest Base Camp Trek a few weeks ago. Out of 8 people in our group there were 5 of us wearing Osprey packs. I had the Scarab 30 and loved it. We hiked in sun and rain, hot and cold, through wood and over rock fields. This pack was on my back every day every step of the way. The bladder was full with an extra bottle of water on the side at the waist belt and the bag was full with essentials for weather swap outs and everything i needed to get from A to B and survive without my big duffel. It never chafed my shoulders or waist, felt great on my back and did n't sweat me up by allowing air to flow around it. It was exactly the right choice. The design of the bladder makes it very easy to fill and shove back in its home. the only thing i would change or add would be a cover over the drinking port. We were dropping our packs in a lot of places, on trails in Tea houses, coffee houses and different temples, everywhere and the drinking port always ended up on the ground. Would of been nice to have some sort of cover.

5 Rose M.
I love this pack! It's big enough to hold everything I need for a long day of hiking. Holds lots of water, all the zippers are strong, the size of the compartments are perfect. I ca n't say enough about this pack! And Osprey as a company is fantastic, they stand behind their packs and fix any issues you may have. I wo n't buy a pack from any other company but Osprey! Highly recommended!

5 Kïdd34
Not sure why all of the neg reviews on cleaning and use but this thing is very easy to dry out and works perfectly at 80 mph on a Harley you have to be smarter than the reservoir Yes hose when it's hot out gets very pliable but what product would n't just have to be smarter than the hose To clean 2 paper towels empty out the water then wipe out u can get around the hose attachment area and then once again for a almost complete dried out reservoir I then took a spaghetti spoon and stuck it inside to keep the reservoir open woke up the next morning and it was dried out Other than that most of you are on two feet I was on my Harley 10 states mostly 80 mph and it was flawless I truly do n't see myself needing to purchase a new one ever

5 Bryon
This is better than the stock one that came with my pack.

Frequently Asked Questions For 3L Hydration Reservoirs

A 3L hydration reservoir provides ample water supply for extended outdoor activities, ensuring you stay hydrated without needing frequent refills. They are designed for easy access and convenience, allowing you to drink hands-free while on the move. Additionally, these reservoirs often feature lightweight materials, making them ideal for running, hiking, or biking.

3L hydration reservoirs are typically made from durable, BPA-free materials that are designed to withstand outdoor conditions. Many feature a blend of flexible plastics that allow for easy folding and storage, while also being resistant to leaks and punctures. Some reservoirs may also include antimicrobial treatments to help keep the water clean and fresh.

When selecting a 3L hydration reservoir, consider factors such as the type of activities you'll be doing, the fit with your gear, and the ease of cleaning. Look for features like a quick-release valve for easy refills and compatibility with your backpack or hydration pack. Additionally, consider the weight and design to ensure it meets your comfort and performance needs.

Yes, a 3L hydration reservoir can be used in cold weather, but it's important to take precautions to prevent the water from freezing. Insulated reservoirs or those with insulated sleeves can help maintain the temperature of the water. Additionally, keeping the reservoir close to your body or using a tube cover can prevent the drinking tube from freezing during colder conditions.

Different styles of 3L hydration reservoirs may vary in design, such as the shape of the bladder, the type of drinking tube, and the method of attachment to your gear. Some reservoirs are designed for specific activities like trail running or biking, offering features tailored to those sports. Others may prioritize lightweight construction or added insulation for different environments.
