2x10oz BPA-Free Water Bottles for the Running Hydration Belt, Fuel Belts Replacement Bottle Set for Marathon Walking Hiking Cycling Trail Skiing（2 Pack）

Perfect size of water for runs. Fits comfortably in my running vest and isn't too bulky or heavy, also is very easy to hold while on a run.bottle feels nice and thin but pretty durable for the most part.its been pretty easy to clean with a bottle brush so far.Ive had these for a couple years now and they are still holding up amazing.If they ever give out I definitely would buy these again, favorite running bottle by far.

Outstanding customer service. Best water bottles I’ve ever purchased.

Great on my run!It fits perfectly in the side pocket of my running pants.

Work well, but have a tendency to leak a bit.

I use these for my kids lunch boxes. They can’t have cows milk for else… y’know. But they love the chocolate milk and get tempted at school. After having some issues of letting them drink it for a week I had to intervene and help them have exactly what the other kids get to choose for lunch. And so I make their dairy free chocolate milks in these. They’re the perfect size for the lunch box and also for them not to get too full on a sweet drink. It’s basically the same amount you get in the school lunch carton. They don’t leak. Easy for my 5 year old and 11 year old to open and close. Smells normal lol and super portable! They get the job done.Sometimes they’ll request a different type of drink. So it’s nice to be able to send them with something healthier than the school lunch options. It still makes them feel either included or not doing without just bc they don’t do school lunch.

These fit in my running shorts pockets and also in my older Fuel-belt holster as long as I use the top loop to secure the bottle. I like that they hold a few more ounces than the 8oz bottles that came with the Fuel-belt. They haven't leaked and don't taste any worse than other plastic bottles.I attached a pic of the 10oz black-capped bottles next to my older 8oz bottles for comparison.Have fun!

I had a running belt with such bottles for several years, and was more or less happy with it. Eventually the original bottles broke (which is fine, they served for many years), and I bought this replacement. It is much worse than the original. It is hard to close the cap stopper tight enough that it does not leak, but it I manage it, it is even harder to open it. I have to choose between water leaking or hurting my teeth (on one day my gums started bleeding). So if you buy this as replacement, keep the old caps (or use some other caps).

The price was good and its use was great.
