I got this flask with points and just wanted to check it out. I really like that it's supremely easy to clean. It sincerely DOES NOT LEAK--my friends and I were squeezing it (with a good amount of force if not a bit cautiously as we were at a restaurant) and it did not leak at all. When full, it's a generally pretty solid shape and as you're drinking out of it, it of course sags and loses it's shape, so obviously not necessarily a vessel for placing on a table.

Love the wider opening, especially for pouring tailwind/electrolyte mix into… but it does not have markings on the side for mL like most other Hydrapak flasks.

This seemed disappointing, especially since Tailwind encourages monitoring consumption of the thicker Tailwind mixture over time or the regular mixture as your body adapts.

I don’t care much. My flask is in my running vest until it’s empty anyway— so you decide if this is a game changer for your fueling/hydration strategy.
