MardingtopHydration Bladder, 2.5 Liter Leak Proof Water Bladder,Military Hydration Pack Replacement for Hiking Biking Climbing Cycling Running Camping Backpack.

The attached straw seems to fit tightly, with no leaks as of yet. I will be using this item in an upcoming camping situation, so I will update the post if any issues arise. Seals seem to be holding for now.

Lo imaginé de un material más resistente aun no lo e usado espero sea vuen material

I used this item once to test it out before a long distance ruck and it ripped along the seam. Filled only halfway with water, nothing else in the bag that could have ripped it (no additional weights or items, just this bladder in my rucksack. It ripped along the seam by the end of the 5k hike. Return/replacement window was too late as I got this as a gift a few weeks after it was ordered. Would be willing to alter my review if a new one is sent and it does not rip upon testing.

I'm a bit disappointed with the size and the feel of the bag..Does not feel like something quality. My Mistake so I'll look for another alternative to this.

Very poor quality

Nothing special about it but it does the job and hasn't leaked. It came as a free add-on with a pack I purchased.

This garbage ripped before I even filled it with water! How important is your water supply? I know that in Texas it's pretty darned important.

Bought this with same companies 28 liter backpack, which AMZ provided as 'bought with'.Nothing against this item, except the seller needs to do better job of matching items for useability.Returned, looking for alternatives that are better adherence to purpose.
