I’ve owned MANY Miir bottles and tumblers for years now. They’re my go-to for daily coffee water at work. Great insulation, cool colors, and awesome branded options at a lot of the coffee shops around town.
I’m NOT a fan of the sip lid. it has weird geometry to it and the liquid doesn’t flow out the straw as well and doesn’t stay nearly as cold as with the normal twist lid.
I have two Miir mugs from their collaboration with Topo Designs. The coated metal mugs are both sturdy and functional while also looking cool. They keep an iced beverage cold for several hours.
I use the 20 oz bottle everyday for my coffee. It keeps it either cold or hot. I have had it now for at least 3 years and still works perfectly.

This is the best travel coffee cup I’ve ever had and I’ve tried a lot. It keep your coffee hot for an absurdly long time, feels good in your hand, drinks great and is easy to clean. All the things you want in a travel mug.
I purchased the 16oz tumbler. I love it. I love the feel and how it fits perfectly in the cup holder in my car. I use it for my coffee in the morning and then for water for the rest of the day. I purchased the white tumbler. I was worried at first that it would stain but have had no issues at all. Highly recommend!
