Flexible Collapsible Water Bottle (2-Pack) | 5oz, BPA/PVC Free, Ideal for Hydration Packs, Running, Hiking & Travel

This is a great little water bottle. I really like the feel of the silicone, I use it nearly everyday and it is holding up fine. As much as I love it, there are three things to be aware of before buying it:#1: It is small. It is hard to tell from the pictures, and even in person it looks like it would hold more water than it does. This is both a good and bad thing, it makes it light and easy to travel with, but not a lot of water. I think it is about half the size of a standard plastic bottle. On the plus side, this means it easily fits in a bag or purse. It is actually small enough I could carry it in the side pockets of my leggings. Not sure how comfortable that would be, but it fits.#2: It does not stand up on its own. This is very clear from looking at the design of it (it does not have a flat bottom) but somehow I did not expect that. This is not a problem if you plan to take it in a bag, but I would not take it out with me and set it on a random table because it can be hard to keep the nozzle off the ground.#3: To drink water out of it, you use your teeth and put pressure on the top and bottom of the silicone part of the nozzle. (This was the weirdest one for me.) This breaks the seal and lets the water out. It was strange at first, but I really like that aspect now. I makes it almost impossible for the bottle to leak, at least through the nozzle. And you don't have to worry about any kind of cap. It also makes it easy to use with just one free hand. I was worried this would wear out, but I empty and refill this bottle multiple times every day, I have had it for months now, and it is shows no signs of wearing out.As long as you are okay with a little water bottle, I really recommend this one. I would not take this on a multi hour long hike, but when I go out for a walk, or run to the store, this one comes with me :)

There are so many options for water on trail. I narrowed my requirements to:1. As non-toxic as possible2. Small enough to slip into pockets of my underwear. (Yes, that is a different review. No vest, no bounce, etc...)3. Easy to useThis bag/bottle covers all three requirements. Silicone is considered much better than plastics for health. The 8.5 oz size fit into the picket. That said, it still bounces a little but I will get used to it. Being collapsible means it never sloshes. It also means I can squeeze the bag to get faster water release. And the bite nozzle works better than many I have tried. Overall, I am very happy with this purchase.

Super lightweight, functions as promised. These have been great in my long runs and fit neatly into the pockets of my running vest.

I love to use the bottles when I'm out running or skiing. They shrink as I drink and never slosh around in my pockets, it's awesome. The drinking valve is very comfortable to use, doesn't leak, and delivers the right amount of water with the right pressure. But depsite washing them many many times, the horrible chemical taste of plastic and rubber never goes away. It's very unpleasant, to the point where it feels unhealthy to drink that water. Too bad, otherwise it'd be a 5-star rating.

Absolutely love these for running. Don’t have any leaking issues in my running bag and live that once you drink the water you can carry a smaller rolled up bottle.

The good—they’re small and easy to hold on a run. They shrink as your drink.The bad—water always tastes like plastic. They shrink but get floppy so they end up requiring more of your attention. No insulation, so you can expect to drink warm water on a hot day. I ran in 83 degree weather and filled it with cold water immediately before my run. It was a short and easy pace 5K loop in my neighborhood which took 30 min. I was drinking warm water about 20 mins in.

I love these little water bottles. I debated between these and getting the handheld kind with a handle for my long runs, but I’m glad I went with these. They are affordable and feel great in the hand, but they also fit into the pockets of my shorts, leggings, and running vest, which is super convenient. The size is just right and depending on the length of my run and the heat index I will bring one or both with me. They don’t leak at all either, so they are convenient for travel. I took them on a long trip out of the country, and they took up very little space/weight and could be thrown into a bag or pocket for a hike or exploring around the city.They aren’t super easy to clean. I’ve left electrolytes in them for a couple days before cleaning (oops!) and have seen mold in the nooks and crannies, but as long as you rinse them out (and let dry) right away - or only use water in them - you shouldn’t have this issue.

It was defective , water came out , there is a little hole and I didn’t get to use it and I couldn’t return it because I don’t want to spend my gas going over there
