Perfect way to take extra water on mtn bike

My dual suspension mtn bike only holds 1 water bottle. This is a perfect way to stash more water in my jersey pocket. I remove the hose and screw the mouthpiece into the cap. Easy peasy. No leaks. Drink and done. Bottle becomes nothing. Taking this bottle is more convenient than using a hydro pack. Hydro packs take more effort to clean than bottles. I am gifting this to friends.

Love this!

I've tried many hand held flasks... this is one is amazing! I love that I can easily change it from just a bite valve to a straw so I can use it with my vest or hand held.

Great for backpacking

I have tried a couple other options for a drinkable water carrier in my shoulder strap pocket of my backpacking ultralight shoulder strap pocket. The Ultraflask fits perfectly and works great It is well sealed and easy to drink from.
