Signpost 2.5L Backpack Water Bag TPU Hydration Pouch Bladder for Climbing Hiking Survival

Received this quickly with prime. The bag itself seems to be very sturdy. I used this for a Spartan Race. I had it on for many hours over a 13 mile obstacle race and it held up nicely. The item came exactly as pictured with the actual backpack and a hydration bladder with tube inside. The bladder is removable, but takes some effort. I did remove the bladder before filling and tightened the bottom connection that attached the tube to the bladder. Make sure to check that connection as mine was very loose and would of caused water to leak all over the inside of the bag. After that, the hydration pack worked great, no leaks, easy to drink out of and was comfortable. There is a pouch on the other side to put a few items, but not much once bladder is full. This is a great basic hydration pack and is perfect for mud runs and obstacle course races, it is sturdy and gets the job done!

Great for the price!

So, the person who reviewed this and said they didn't "comprehend the design", probably just couldn't figure it out. -It's not that tricky though. It works well, doesn't leak, the bladder and tube are fully accessible, and it even showed up a day early. Definitely worth the price.

Absolute flawed design makes what could have been a decent quality item absolute junk.There is no access to the bladder in this hydration pack. It can't be removed, inspected or reached, as the pack is completely sewn shut, rather than using velcro to allow access. This means that leaks can not be repaired and issues can not be troubleshot.Mine came with the hydration hose completely stuffed down into the pack and completely lacking in documentation or instructions of any kind. It took me about ten minutes of shaking the bag upside down and carefully digging my finger into the very narrow gap to finally fist the hose and mouthpiece out of the pack.I filled it with water and was completely unable to get any water to flow from the bite valve, no matter the technique, and reguardless of the amount of pressure applied to the bladder. I figured there was likely a kink or defect in the hose where it attached to the bladder, but it's impossible to see far enough down the narrow gap in the pack to visually determine the issue.After ten minutes of trying to adjust the hose blindly in an attempt to release a potential kink, I gave up and packed it back up for immediate return.My impression of the bite valve it that it is very poor quality, though I wish I could have actually gotten water to flow to give it a better test.I can't comprehend the design. Making the bladder completely inaccessible makes it impossible to inspect for defects or correct issues with the product. It's a shame, because the materials seem decent and if I could have made it work, I would have considered it a good value.

fill it up with water before leave your house.that can help you with your body weight and also reduce your risk to get any virus from other people

Not a camalback by any means but it gets the job done.

the plastic cap is not easy to align, so often time it's not properly closed and water leaks out! It's not as good looking as the camel pak, but it gets the job done.
