Era Flip
Love the concept, especially for travel or sporting events. Anything that you need your straw completely covered. Didn’t love it as much as I thought I would, found it harder to slide back-and-forth than expected. Would really love to have seen the new lid with the option to use with the existing area cup just so people who will love the brand can swap lids between the 2 cups for those of us who already have so many. All in all it’s a great design and will probably keep at least one for the times that I want to have my straw completely covered rather than just a straw cover on my OG Era.
I did a return this color but only to get the peach/pink gingham Era flip that was a target exclusive.

Love the hidden straw
The straw is so great to keep germs away. I love the size for all day use and as always my ice stays ice all day long. Glacier colorway is so much prettier in person.

Glacier 40 oz Flip
A must have! I don’t think I would love this cup as much as the original Era but gave it a try. So happy that I did because I’m obsessed with it. Tha glacier blue design is gorgeous and great for summer
