Hydro Flask 20 OZ All Around Tumbler Black

Do not maintain heat

The one downside to this flask is the drink slot. It’s a bit flimsy and could do with a redesign but, it’s workable and just don’t over fill the flask otherwise it leaves residue around the opening and not nice. Other than that, it’s the best flask/travel mug I’ve ever used! It’s simple to clean quickly, the lid fits snug and the heat retention is amazing. I can still have a hot coffee 4 hours after making it!Definitely worth the money 👌🏼

I use this at work just to keep myself always drinking hot tea and it keeps the temperature well. I also tried it on cold drinks and it held pretty good. They're pretty wide in size so if you have small hands, it may be hard to hold with one hand (maybe), but I'm just letting you know as a guy, washing these are easy cause your hands will fit inside and you won't need those sponge on a stick. Only thing I do wish is they made the lid a little more disassemble-able for cleaning cause I'm pretty sure below the slide lid, grime will accumulate over time... I'll probably just soak it in bleach and hot water it down.Definitely something easy to solve and handle so it's nothing worth docking stars as a whole product.About the leakproof, it does it's job and I really don't understand how people complain it's leaking out of the airflow hole... If that airflow hole doesn't exist, you'll be complaining how this tumbler is so hard to drink out of when it's full. The only other place it may leak is the mouth hole itself (even with the lid on), but if you react fast enough to a fall over, the liquid that leaks through is minimal.

Excelente, cumplió mis expectativas

Es increíble cuánto tiempo mantiene tanto lo frío como lo caliente! Mi café me lo puedo tomar hasta 3 horas después de habérmelo servido -evidentemente no va a estar a la misma temperatura, pero si lo suficientemente caliente como para poder tomarlo-

I've had for 1 year and this has become my go-to travel mug. Liquids stay hot or cold for hours. It's not leak proof, instead they provide a small hole to improve flow when drinking and allow some steam to escape. The sliding open/close groove is easy to use with 1 finger or thumb. Dishwasher safe and has not rusted or inside. I also like the ability to purchase additional covers without replacing the mug, such as the straw cover for cold drinks.
