Hydrobak Hydration Reservoir Bike Pack

I do a ton of 1+hour runs and this is a great size to stay hydrated. It does sit high on my back but I really have no issues with that. I was way more concerned about it moving around while I run, but it stays put just fine. I read that some folks could not put a phone in the little pocket but my iPhone 17 and a key to my truck just barely slides in there. I do not use a phone case, so maybe that’s the difference. I REALLY also like that it’s not made in China! While the hose does not have a quick disconnect at the bladder, I don’t think cleaning will be an issue due to the small size. I tend to give these types of collapsible water holders a quick clean and rinse and then just stick them in the freezer, which prevents mold.

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’ve been using the CamelBak Hydration Pack for a while now and it’s been excellent. The design is lightweight but very durable, and it sits comfortably on my back even during longer walks, hikes, or outdoor activities. The straps are adjustable and don’t dig in, which makes a big difference when wearing it for extended periods. The water reservoir is easy to fill and clean, and the bite valve works smoothly without leaking. I also appreciate that the water stays cool longer than expected. There’s enough storage space for essentials like keys, phone, snacks, and small gear without feeling bulky. Overall, this is a high-quality hydration pack that does exactly what it’s supposed to do. If you’re active outdoors and want something dependable, this CamelBak is definitely worth it.

I bought this for festivals/raves and it works very well plus seems high quality. The seal does not leak though occasionally residual liquid in the nozzle will drip slightly. Works perfectly with electrolyte powder but I would recommended flushing out the system with plain water after use. My only complaints are that the hose sticks out in front of me about 6in/15cm and that the pack is quite small. 50oz liquid capacity is not enough to last me more than a few hours in particularly hot conditions while dancing. There is just enough space for a few small items (wallet, gopro, phone, etc.) but definitely keep them at the bottom of the pack (below the bladder) if pickpockets are a concern. After a few uses, I ultimately decided to eat the cost and upgrade to a larger capacity 100oz CamelBak MULE.

I used this on my solo hiking trip through Arizona's caves and caverns. I also hiked to several vortex locations in the crazy AZ heat. It was a great companion and a must have. It packs easily as it is very small when it is empty. I packed for 3 months in only a carryon luggage and it fit just fine in my bags, without taking up too much room. It holds a lot of water and is easy to wear and use. It's made for these types of trips, as the pockets and straps all made perfect sense. When you want to drink, you bite the tube to suck out water. This prevents you from having leakage this wasting water. A great buy and worth having.

I started using this when I was sick of losing my stride carrying a water bottle. Using a bottle gets really awkward if you’re running low on liquid and you have to do an exaggerated tilt to get the final drops out. Using this Camelbak allows me to bring more water than I can usually finish and I’m able to place the straw in a way where I just slightly turn my head to take a sip; much like a running hamster (with the same body type too!) I’ve used these things in Iraq and the thick nylon ones will last a lifetime. These smaller ones are just like wearing the bladder directly on your back without much in the way. The little pocket barely fits an iPhone X with case but that’s just height-wise; it can fit extra stuff like gels slotted behind a phone. I feel like this can easily go inside a middle pack pocket without adding much size. The fit takes some getting used to, but I like that it sits high on your back. I do like the others and turn it upside-down to let the excess air out so it doesn’t slosh around, other times that I forgot to do this, it’s a good alarm to let the slower runners know to make way. Overall this is a great tool to add to your fitness routine without messing with your stride or regular “get up and go” regiment.

Great! Wish they had just a touch more space to put a phone and a snack.

Fit is well and nozzle is easy to use. Very lightweight and perfect for mid range activities where you don’t need extra space for snacks or a large bladder.

Je l'ai utilisé en marathon et c'était parfait. C'est léger et de bonne contenance. Très pratique !

Quality as expected.

El sistema de la boquilla es muy bueno, evita que entren elementos en el sistema. Buena capacidad para recorridos cortos o medios. No hace presión en los hombros. Recomendado.

Utilizei a mochila para subir o Pico da Pedra, próximo à Camboriú. A capacidade do reservatório de água foi suficiente para subir e descer o morro e ainda sobrou metade da água. A mochila é muito confortável, leve e o sistema de hidratação é perfeito. O pouco espaço atende sua função, que é de ataque rápido, em muitos momentos não lembrava que estava com a mochila, tamanha a adaptação do projeto. Tenho outras mochilas da Camelback e esta tem o mesmo padrão. Recomendo

Llego en perfecto estado.
