2 Pack Hydration Bladder 2 Liter/70 oz - 1.5L 2.5L 3L Water Bladder - BPA Free Hydration Pack Replacement - BPA Free Hydration Pack Replacement

These are really great. The big mouth opening makes them very easy to fill, and, maybe most importantly, dry out when you're done. I also really like the detachable hose. Great product, recommended.

I'll start with the pro and cons.... Pros: Perfect fit for my Osprey backpack and a generic hydration pack 100% leak-proof during my entire 5-day trip to 3 Utah national parks Wide opening makes filling and cleaning quick and easy Comfortable bite valve with smooth water flow and no drips Protective cap keeps mouthpiece clean on dusty trails Durable, high-quality materials that feel as good as premium brands Great value: quality matches more expensive hydration bladders Cons: 2L size is ideal for short to medium hikes but may be too small for long, strenuous hikes (I ran out of water by the summit of Angels Landing in Zion) but this was poor planning on my part. My Experience: I bought the Baen Sendi Hydration Bladder 2L to stay hydrated while hiking in Zion, Bryce Canyon, and Arches National Parks. It fit both my Osprey backpack and a generic hydration pack perfectly, with zero leaks the entire trip. The large opening made refills at trailheads quick and easy, and the protective mouthpiece cap was a thoughtful touch, especially in dusty desert conditions. For short day hikes, trail running, or cycling, this water reservoir is perfect. If you’re planning an all-day trek, I’d recommend going for a 3L version. Overall, this is a reliable, durable, and easy-to-use hydration bladder at a price that’s hard to beat. I’ll definitely buy another for future adventures.

does not fit perfectly in all back packs

ALWAYS buying these when i need new bladders for my danpak. they're super lightweight, easy to clean, last long, and i have yet to experience any leakage. they're also very durable. only reason i eever find myself buying a relacement is if i forget to clean them out after a festival. they fit in my danpak hydrobags relatively easy, but i will say they do fit kinda tight when full and i have other things in my bag, but that's moreso a bag size problem. not really the bladder's fault. they're also priced really well compared to other amazon options and in store options. most places i find just one for $12-18 whereas im getting 2 for 1 with these basically.

These dont leak and the connector from the hose to the hydration pack is easily removable and very continent

Just put the blue one in my backpack today. Once I get used to how to close it once it’s full of water, all will be well. I LOVE how easy it is to bite when you want to drink! I also love the cover for the drinking valve!!👍🏼😊❤️❤️

This fit my 35 year old Camelbak- just had to turn the handle/hook the other way and it's great

Not very high quality. Which does match the price I suppose. They did work to start with, the straw is quite small so it's hard to get much water fast. After about a dozen uses. The bladder started leaking. And after a few more uses, the straw wouldn't seal anymore either.
