I got the 40oz Hydro flask with the straw. I found the straw a bit of an effort to suck on, and I never got that nice cool gulp of water. I took the straw off and it's much better. Yes, I have to hold it up and still suck on the mouthpiece, but I get nice gulps of water. I also don't care for the one finger carry design, a bit heavy with 40oz.
