Great investment, works well for skiing, running hiking and biking
I use this all the time and have had for almost a year. Great for running, ski trips, biking, really anything. Small and compact. The cap and surrounding support mouth cover is hard and sturdy so it’s not completely collapsible, but pretty close. Ultralightweight. No insulation but that doesn’t matter to me. Didn’t notice any major smell or taste when I first got it, but I made sure to wash it out with warm water. I wouldn’t put it in the dishwasher, hand wash only if it gets really dirty. I use half of a hydration reservoir cleaning tablet and that has solved any issues. Fits in my Gaiam running / hiking adventure belt.

Great for day trips and cross body bag.
I bought these collapsible water flasks to put inside a cross body bag for a trip to europe. They were absolutely essential for day trips around different cities. They are flexible enough to go in the bag and no one even noticed them but had a good drink of water for the day. They’re very durable and easy to squeeze out the water. Definitely recommend this for your bags.

Great bottle for running
I use this for my runs and walks. It’s great, fits in my little running fanny pack. It doesn’t leak, and doesn’t have a plastic taste if washed before use.

Leak proof it is NOT!
Great idea. But it leaks so badly. Poor quality. It’s not leak proof. At all.

Great for Races and Trail Runs
Bought these to try out for trail running and I’m very happy! They are super light and take up very little space in my running vest. That makes them great for trail running and short hikes.I used one for a 12 mile mountain run last weekend and had great success. No leaks, easy to open, easy to drink from. I’m very happy with them and would purchase again or recommend to other runners and hikers!

Reusable drink pouch for kid school lunchbox.
Works okay as a drink vessel for kids school lunches. I purchased due to size and the cap feature being attached to spout. Pros: Can fill easily with water or juice. Will fit nicely in a lunch box with limited space. Easy for kids to drink from, they need to suck and bite on the spout like a straw so it’s mostly leak proof. The pouch material is thick. Cons: Cleaning & drying pouch can be tricky. Sometimes the lid won’t line up perfectly with pouch and it will leak. The silicon spout can split if you bite/chew on it. Overall, a good purchase for what I was needing. Product has lasted 8 months, both pouches being used 4x a week.

Handy for long walks
I have dry mouth, which is even worse when I take long walks with my dog. The 5 oz size fits perfectly in my pocket. No artificial taste from the product material. After emptying the pouch at night, I secure it upside down in a juice glass; it’s dry by morning. Recommended
