Wonderful product!

I love that I can refill this and not have to mess with single use gels. I've never had an issue with it leaking and will most definitely be purchasing more refills in the near future.

Needs a Cap design

Since I use this when running with gel and water, so a normal water cap design would work. The problem is when you open it to drink. It twist in the same direction and leak, leaving a sticky mess. If the opening twist was in the opposite direction it might work better. Please either redesign or offered two options since it is otherwise a great little flask.

Hiking - Plane - Meeting -Mini Water Bottle

Its perfect for about an hour hike.

I put in my yoga side pockets during my workouts and it’s thin in shape and doest stretch my phone pockets out.

I can keep in my suit jacket while in a meeting and it’s not noticeable.

Great for the plane or skiing too!

Make sure lid is on tight.
