My Favorite Cup

I wasn’t sure if it was worth the hype. A few people love their cups from another brand, but I loved the sleek look of the SM tumbler. After a frustrating trip where my previous water bottle rolled into the floor I caved and bought what is now my favorite cup.
The handle makes it easy to carry. The base mostly fits into my car’s cup holder(and fits perfectly into my husbands car and my best friends cars) so I don’t have to worry about the cup rolling into the floorboard. It keeps my drinks cold ALL day and I am encouraged to stay hydrated.

2nd time buyer.

My 1st purchase I got the graphite for my husband, and the chartreuse. I have been waiting for months for the riptide, and moonlight to be in stock again. So I immediately bought them when I saw again. I've been loving them so far. My kids love to drink from my cups too. With all the lights in my kitchen the color of my cups really become brighter and pop. But it actually the dark shade that is advertised online. I love the colors I've bought so far.

Damaged on the first wash

This is my second Trek and I love the style but unfortunately I missed that the special edition is super delicate. Yes, it was user error, but I have a handful of cups from SM and all are dishwasher safe. Ordered this one and didn’t realize it was hand wash only until it went through the dishwasher and got ruined. I wish that would have been more clearly advertised. :( Make sure to always check your cups!
