Hydro Flask 20 oz Stainless Steel Reusable All Around Tumbler Black - Vacuum Insulated, Dishwasher Safe, BPA-Free, Non-Toxic

It keeps the temperature so well that I even need to open lid a while ,before drinking👍🏾. The lid seals very decent , obviously you won’t throw it into a bag pack or tote. Highly recommend for using for to go on drive or at home/work.

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 👌🏼

Do not maintain heat

Lid is broken and leaking

Absolutely love this, from the feel, the look, it's great! Also keeps hot and cold very well. Also it's lead free, unlike other brands such as Stanley and Yeti that use lead in their insulated products.
