Review on 🎒 Ultimate Hydration Pack: Lightweight Water Backpack with 2L Water Bladder for Hiking, Biking, Climbing by Ron Long

I haven't had any major issues with this Hydration Pack. Does not leak when properly closed. So far I've never had a leak on me. As the fluid sac fills up, it looks more like a ball in the middle of my back. It flattens out as the pouch gets smaller as you drink from it. I'm not sure how to avoid this. Maybe it would help if the bag had 2 straps that could be looped into the top of the bag. Liquids don't like to stay flat in gravity. They tend to fall to the ground and gather there. Delivery works well once you get used to the mouthpiece. There are no leaks either, but I always close the end valve while it's still in my mouth. Cleaning is the harder part, but not impossible. I rinse it out with water, shake it as much as I can, dry it with a paper towel, then stuff a paper towel into the bottom of the big hole and propped it up in front of the blow dryer on cool to finish drying it on the inside of the bag. If you don't do this, mold will damage the bag. I am comfortable to wear. I think you could use this for a 10 mile walk pretty easily if you don't take big gulps. 2 liters of water is a lot. The backpack also takes my iPhone 8 with case in the zippered compartment. There is also plenty of room for keys. It's very reasonably priced and worth it if you enjoy walking long distances and not having to stop to fill up. I would definitely buy it again.
