2 Pack Hydration Bladder 2 Liter/70 oz - Water Bladder Pack of 2(1 Piece Blue+1 Piece ArmyGreen) - BPA Free Hydration Pack Replacement

I'll start with the pro and cons....Pros:Perfect fit for my Osprey backpack and a generic hydration pack100% leak-proof during my entire 5-day trip to 3 Utah national parksWide opening makes filling and cleaning quick and easyComfortable bite valve with smooth water flow and no dripsProtective cap keeps mouthpiece clean on dusty trailsDurable, high-quality materials that feel as good as premium brandsGreat value: quality matches more expensive hydration bladdersCons: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.

Great system, easy set up and works as reported.

The blue one started leaking from the bottom, where the drinking tube connects. Made for a completely wet pack and gear, as well as not having water for a 10 mile hike.Later on, we found a leak around the fill hole area as well.The green one has not had any issues...so far....

Well worth the money. Works as expected, no leaks and easy to install.

This backpack was exactly what I wanted.

These cubes are amazing! They are well made and take a true stuffing and still zip up without an issue. I bought these for my San Diego Trip and they are definitely high quality and exactly what I was looking for at a reasonable price! I love the the double zippers, it makes closing everything up a snap. As I mentioned before, these are well made and I stuffed them like a turkey on Thanksgiving and they show no signs of giving in or tearing. I love how much stuff I was able to get in these and how versatile they are. I am using one to throw in all of our sweatshirts and then just threw it in the truck. I took the small size and brought along all of our bath suits and water shoes to Lego Land so it would fit in our tiny stroller storage pouch. I would DEFINITELY order these again. If you are not sure about ordering these and are comparing them to the other packing cubes out there, just buy these and start packing!I was able to purchase this product at a discount in exchange for an honest review. As a budget minded shopper, I constantly check ratings on Amazon before I make any online purchases. This is my honest opinion of this product, and as a teacher, I feel that honesty is the best policy. I tried to list all of the positives and negatives (if any) of this product so you can make an informed decision. After using this product, I can state that it was a great purchase and I would definitely purchase this again. If my experience changes, I will update this review!

Works better than the original I had. Cleans easy, great water flow. Holds enough for a full run with my boys.

Filled it up, closed the lid, went to a trail. Only to make it 0.1 mile before it started leaking everywhere. I thought ok maybe it’s user error? I readjusted and then the leak got bigger. Same thing happened in the other one for my partner. Don’t buy this. It’s $18 because it’s plastic junk, I should have known better. Time to go REI and buy a real bladder. Refund is on the way.
