Adalid Gear Water Bottles (2-Pack) for The Running Hydration Belt : BPA-Free & Leak-Proof

The quality of the plastic is good. I have no worries about them just springing a leak for no reason. The cap is a pop-up type and does not leak. Also, no issues with slime growing on the inside of the bottle or cap. They are dishwasher safe. My running belt only holds 1 bottle. The size of one bottle is big enough for up to a 5 mile run. Anything longer than that and both bottles should be brought along. The bottle weight when full of liquid is not enough to really notice when running. No "sloshing around" or bouncing in my running belt. I like the curved neck of the bottles. It makes it easier to drink. You can suck the liquid out or give the bottle a gentle squeeze. I've used the bottles about 10 times now. I expect the bottles will last a long time as long as they are not mistreated.

I purchased these to replace two older bottles I have been using on my running belt that were leaking. I have used these on two long 15+ mile runs and they worked great. The did not leak while I was running or drinking from them. They are a little bigger than expected (bigger than old ones) but that was my mistake for not checking size details, but they still fit in my running belt and nice that they hold a little more just hard to get out sometimes.

I ordered these water bottles to replace ones that came with my running belt that were too small to keep me hydrated on longer runs. These fit great in the belt I already owned and they are a better quality than my initial pair. They are just the right size at 10 oz - not too big and not too small. They fit just right in the belt and they are a sturdier, slightly thicker plastic. The lids screw on and off very easily but are definitely leak-proof. The threading on my older bottles was terrible so I had to be careful to get the lids on just so, or else they'd leak all over. A good price for a good product and they came quickly!

I got this about six months ago and have run < 50 miles with them since I bought them. The caps are already leaking everywhere, making it an issue because my leg will be covered with sticky sports drink halfway through a run.

Worked great with my Nathan hydration vest! No leak top perfect for my 15mile run last weekend

I needed something small, light weight and leak proof to put water in for my kids' lunch boxes (it's surprisingly hard to find a water bottle that fits in a kids lunch box). These work exactly as I had hoped. No leaks, even when full and turned on its side. We also use them for hiking and walking with the kids. They are light enough for small children to carry themselves.

Recieved the bottles prompty; nicely packaged. I used them during a longer run (6.6miles) yesterday; no leaks. The caps/spouts are easy open/close while running; without frustration. These 10oz bottles also easily fit into my husband's running belt as well, so very versatile. Very pleased with the product.

Don’t get these if you don’t like the drink to go down your shirt. Leaks and cap does not lock in place :(
