8L Hydration Packs Backpack

I bought this for walking, so I can't speak to stability for running, but may review should cover biking. This pack is just for hydration. There are no pockets for gear, phone, etc. Keeps it light and single-purpose. I followed the instructions and froze the bladder full of water and a little lemon juice. Took hours to thaw, but no weird taste from the bladder afterwards. The bladder is easy to fill and the lid screws on easily and securely-no leaking. The ideal way to hook it to the pack is by slipping the thinnest part of the hook through the gap in the bladders' hook, rather than trying to pinch the hook onto the bladder because it feels flimsy and breakable. Passing the tube through the pack and down the strap takes time, but is typically of all hydration packs. The tube is naturally curved upward, which is really convenient. Once passed through the loop on the strap, you can cross it over and up the loop on the strap on the other side (after putting the pack on. I filled the bladder to 2L and took a 25 min. walk and felt like there was nothing on my back. I had cinched it up so it fell just below my waist (I am 5'5"). The front horizontal straps are well placed and comfortable, and cinch up comfortably. The buckles are good quality. The mouthpiece is fine, but leaks a little after a sip and must be flicked to shake off any water after closing or you'll get water on your clothes. You can always swap out this bladder or buy a second to keep a cold one available. I like wearing this pack while walking because it keeps my sun shirt from flapping so my arms are free at my side and no water bottle at my side to interfere with my arms. The price was good and this is a well made item. If you want storage there are plenty of other packs that have lots of storage, but for an exercise walk this is great.

We’ve used this for two summers of band camp in 95+ degree weather and it should be good for one or two more. The backpack is large enough that it can hold a second bladder (1 water, 1 electrolyte) plus some cold packs. It’s easy to clean and doesn’t leak so far. I lost a gasket on one if the straws, but was able to add a little plumber’s tape where the gasket was and the seal holds. Quality product that does the job.

awesome. it works great, no leaks, good design, very easy to fill up and port. Material is really good quality and it doesnt make the water taste like rubber which is really nice. Fits the full 2 liters and its super easy to adjust.

This backpack with bladder hydrating system was the perfect size and weight that once on you quickly forgot it was even there! The fasteners are perfectly placed so the backpack stays secure no matter how strenuous your activity. Along with the perfectly sized bladder with tube and mouthpiece, it had just enough space for a phone, keys and even a map if needed. It functions as the perfect hiking accessory with all your basic tools readily available. I also found that adding a small amount of ice to the bladder prior to filling with tap water was all that I needed to keep it at a perfect drinking temp throughout an entire hike in 85 degree weather. The one major issue I had, though easily self resolved, is one I truly believe all companies producing these similar hydration backpacks suffer from. There is no question that, due to the fact that this product’s main function is to store and deliver drinking water to the wearer of the backpack as they wear it at any event they choose. Because the bladder therefore is a product that would be required to meet standard safety protocols with respect to food or drinking products (for example, this product clearly identifies as a BPA free design, which is incredibly important to buyers of water bottles or other similar products) it would naturally need the user to ensure it is cleaned at the time of purchase as well as after each use. Yes this product does not come with any kind of instructions whatsoever as to the appropriate care and cleaning required prior to first use and each use thereafter. In fact, the only way I knew that I needed to obtain a separate product to clean it and which one would work best with this particular design, was due to the wonderful reviewers of this product On Amazon! Thank you! I was therefore able to get a cleaning kit that would fit the exact size of the bladder and give me the long cleaning wands etc needed to ensure all areas that either must be sanitizer for drinking water or are in contact with your mouth etc. If it weren’t for this advice, I might have purchased it and inadequately cleaned it due to the fact that standard kitchen cleaning aids will not access all the areas that need to be fully sanitized. THIS PRODUCT, and all like it (as many I saw have the same flaw) should come AT THE VERY LEAST with clear instruction on how you must sanitize the product to prevent possible contamination. But because these products are so unique and require a custom system and tools to clean it, I believe they should be required to come with the cleaning tools and instructions that fit their products design and allow for its effective safe and continued use. This is why the only picture I have attached (as I have said that the rest of the product is absolutely wonderful) is a picture of the cleaning system I had to buy on Amazon that would fit the bladders width and design perfectly to allow for a full sanitary cleaning each and every time needed and a way to dry out the system after each cleaning is complete. Surprisingly, the backpack includes a hook at the inside top of the unit to allow for it to clip onto the custom hanger included in the cleaning system kit so you can dry it overnight and it won’t fall off. Who knew! Thanks for baring with me on this extended and probably way too detailed explanation of the frustration I continue to face with products like this which literally cannot provide their intended use without the purchase of a completely different item but neglect to tell you so when you buy it. But hey, we all have time to go through a hundred of wonderful reviews to educate ourselves so they don’t have to education us. And. Now AI is even doing it for us in some Cases! What’s next! On to my next review THANK YOU!

Good product and the zipped compartment was handy for phone and a snack pack

A little backpack that holds a lot! It was used at a music festival mainly for water but it held all the things I needed for the day!

I bought this hydration pack for bike riding, and it has worked out great. The backpack is lightweight and comfortable to wear, even on longer rides. The shoulder straps are adjustable, and once I got it fitted properly, I barely noticed I was wearing it. The 2-liter bladder holds plenty of water, and I love being able to take a drink without stopping or reaching for a water bottle. The bite valve works well and doesn't leak. Filling and cleaning the bladder was easier than I expected, too. There is also enough room in the pack for a few essentials like keys, my phone, snacks, and a small wallet. The material seems durable, and everything feels well-made for the price. Living in Alabama, riding in the heat means hydration is a must, and this pack makes it so much easier. I'm very happy with this purchase and wish I had bought one sooner! Pros: Lightweight, comfortable, holds plenty of water, easy to drink from while moving, good storage space. Cons: None that I've found so far. If you enjoy biking, walking, hiking, or any outdoor activity, this hydration pack is a great way to keep water handy without juggling bottles. 🚴‍♀️💧

The bag works well if you are just getting into hiking or running. But it doesn’t last very long. My bag has already broken at the seams and it does leak like a lot of people have found. It does hold a decent amount of water but I would say that it is hard to fill once to get to the top as it spills out easily. I do like that there is a whistle on straps. I will likely invest in a bag with a better quality and more space for hiking snacks.

I've been really happy with this Unigear hydration pack. It's lightweight, comfortable to wear, and the adjustable straps keep it secure without bouncing around. The 2L water bladder is easy to fill and doesn't leak, making it perfect for hiking, biking, or long walks. There's just enough room for my essentials, and the quality has held up well. Great value for the price—I would definitely recommend it.

I got this hydration pack backpack for my outdoor adventures and I’m very happy with it. It is light, strong, and comfy to wear. It has a big main pocket that can fit my stuff, like food, phone, keys, wallet, etc. It also has a small front pocket that can hold some things, like sunglasses, sunscreen, etc. It has a shiny strip on the front for safety at night. The best thing about this backpack is the water bladder. It can hold a lot of water, like 70 oz or 2 liters, which is enough for a long day of running, hiking, or cycling. It doesn’t leak and it is easy to fill and clean. It also has a bite valve that is easy to use and doesn’t drip. The water bladder is cold and has a tape to keep the water cool. The backpack fits well on my back. It has a chest strap and a waist strap that help to balance the weight and keep the backpack steady. It also has a mesh back panel and shoulder straps that don’t make me sweat or hurt. The backpack is made of good nylon fabric that is water-proof and rip-proof. I love this hydration pack backpack because it helps me stay hydrated and have fun in the outdoors. It is handy and easy to use. It works for any season and any place. I think anyone who loves outdoor sports would love this product.

Works quite well for the price, have been using for 2 weeks biking and seems to be holding up. The small size is really convenient, and most of the time I forget I’m wearing it. Has one tiny pocket in the front that’s big enough for you wallet etc. Supplied tube is plenty long enough and bladder seems durable (rinse it a lot before use, funky taste lingers). I’m a larger framed person and this fits pretty well, both straps do adjust and fit (usually only use the top, find that’s enough for this). Only a few gripes, one is it starts to heat up with you, so you’ll have warm body temperature water after an hour or so. I throw a few ice cubes in before I leave, seems to help with that. A little piece of insulation between the bladder and your back would probably help on hotter days. The second is the little rubber mouthpiece on the end. It works like more expensive bags (lightly bite/press to open) but I find it dribbles easily. There is a valve that can close the flow off right at the end, but it’s kinda weird to fiddle with while riding, and not sure how durable the little handle is. I would buy this again for sure, the size/price/convenience is hard to beat.

Took it for 3 hrs bike ride - it’s a good alternative to Camelbak at half the price. Good quality bag, large 2L bladder, good water flow, the backpack sits comfortably and caused no issues during the ride.

I got this for hiking and long walks. It's very comfortable to wear and holds an adequate amount of water, most everything is great. Cons: Rinse it and let it sit with water in it for a few days changing it out to get the plastic taste to go away sooner. The lip on top of the water isn't user friendly, it's a huge hole..I like to put ice and water in so I don't get as much as I could because the water squirts out if it's too close to the top when you try and close it. Would prefer a better design. In the end, it works. Used it about 6 times still taste a little plastic. And, I'm careful about how I close it after the water and ice is in. I'll be looking for a better one here soon but this is alright.
