You'll never see me without it!!

I never thought a water bottle would provide me so much emotional support. The design is sleek, the color (Almond Birch) is super pleasing, the handle feels like we're holding hands-- I can go on. My water stays cold for hours and every sip is satisfying. Easily the best purchase of my life. Shoutout to Simple Modern's customer service team for being besties. This whole brand slays.

LOVE the cup and the customer service!

I received the Trek Tumbler as a birthday gift. I had a small problem with the original one and customer service resolved the issue quickly! I LOVE this cup. It fits in my cup holder of my car, the handle is great because the tumbler is so large, and it’s so sleek and pretty!

I NEED THE LAVENDER… when will it be in stock?

Blush Pink

The color of it is beautiful. I am obsessed and have already drank more water than ever! I put ice in the night before with full liquid and have utilized the ice today. I never bought a Stanley, so I have nothing to compare it to but am happy. I bought my best friend the lavender color, and she loves it and recently purchased the seaside color. I love what this business supports and would rather support them than a large chain.

Love this cup!

I received this as a gift from a co worker. I freaking loved it. Unfortunately it was stolen and was hoping to replace it. But it seems they no longer make the lime one anymore. I would love for them to make that color again!
