Great Quality Product
This 3L bladder exceeded my expectations. I tested is in my sink overnight to see if it would leak and it didn't. Then I filled it up and took it on a 5 mile hike and it didn't leak anywhere. I was so relieved since my other name brand bladders always ended up leaking from the bottom of the bladder no matter what I did. It is long and skinny which is a different shape than other bladders I own, however, it fit perfectly in my day pack. The tube is also the perfect length and I didn't have to worry about it bouncing around or tuck it behind the strap. It's durable and the material is smooth and sturdy. I'm very happy with this product and will buy other sizes in the future.

Solid Hydration Bladder for Long Treks - Day Hikes - Minor Filling Issues
This hydration bladder has worked well for me on the trail, especially on long treks where I need to boil and store water. It's very easy to clean thanks to the large opening - you can actually get your hand or a brush inside, which is a huge plus compared to other bladders. The BPA-free material doesn't leave any bad taste in the water. The bite valve works smoothly and the on/off feature prevents leaks reliably. My main complaints are that you can't really fill it to the full max capacity without some difficulty, and the filling process itself can be a bit awkward at times due to the opening angle. Despite these minor issues, it's a durable and functional hydration system that gets the job done on the trail. The quick-release tube is convenient for cleaning, and the bonus carabiner clips are useful. For the price, it's a good value for backpacking and hiking.

Kept Me Refreshed at Lollapalooza, Leak-Proof and Easy to Clean
I needed a reliable hydration solution for long days at Lollapalooza, so I brought the Hydration Bladder 1.5L-2L-3L, Leak Proof Water Reservoir, BPA Free Military Water Storage Bladder Bag in the 2L size, and it was a total game-changer for staying hydrated through the crowds and heat. Design and Features: This 2L bladder is made from tough, BPA-free TPU with a secure slide-seal cap and a quick-disconnect tube for easy sipping. The soft bite valve prevents drips, and the included insulated sleeve keeps water cool. It’s lightweight and collapses flat when empty, fitting perfectly in my festival backpack without adding bulk. The military-grade build feels ready for rugged use, even in chaotic settings. Performance at Lollapalooza: At Lolla, I filled it at water stations, and it stayed leak-proof despite being jostled in mosh pits or squeezed in my pack during headliner sets. The 2L capacity lasted through hours of dancing and sweating, with the bite valve letting me sip hands-free while navigating crowds. The cool water was a lifesaver in the heat, and the sleeve protected my dry skin from chafing against wet straps. No spills, even when my wavy hair got caught in the pack straps during a quick re-tie. Ease of Cleaning and Durability: Post-festival, cleaning was a breeze—I flipped it inside out through the wide opening, rinsed it with mild soap, and air-dried it overnight. No mold or funky smells, even after days of use. The TPU held up to rough handling without cracks, and the tube stayed clear after thorough washing. Pros: Leak-proof design perfect for festival chaos. Easy-clean, BPA-free material prevents residue. 2L size ideal for all-day events like Lollapalooza. Insulated sleeve keeps water cool for hours. Cons: The tube can kink if packed tightly in small bags. The bite valve requires occasional cleaning to stay smooth. Final Thoughts: This hydration bladder was my MVP at Lollapalooza, keeping me hydrated without missing a beat of the music. It’s tough, clean, and perfect for festival-goers who want to stay refreshed while rocking out with wavy hair flying. I’d highly recommend it for any outdoor event—2L is the sweet spot for long days!

A must have for hicking
I have done about 350 miles of hicking with this hydration bag inside my backpack. It is a super fit because drinking water is always handy. I really like the actual mouth piece and it's protector. You can always count on it to be clean when you want to drink as the cover protects it well from dust and dirt. In addition, the mouth piece has a valve one actuates with the teeth when drinking, therefore there is no risk of water leaking. The bag is sturdy and I think it will last me few years. The cap that closes and seals the bag is well designed and has a link to make sure the cap is never away from the bag, preventing a possible loss or misplaced cap. I am really happy with this buy.

Great Value, No leaks or Drips
Been using one of these for a couple of months. Very solid design and no issues with leaking or dripping. It took a minute to figure out the bite valve, but it has good flow and does not drip, even if I hike with it uncapped and pulled open. Really good product for the price.
