Magnolia Black 32oz Sport Tumbler

The rubber base is the real winner here — it doesn't budge when I set it down on my desk mid-workout, even after I've been swinging it around. Keeps my water cold through a whole spin class too.

The leakproof lid actually holds up when I toss it in my bag, no drips on my laptop yet. Only gripe is it doesn't fit my car's cup holder, so I end up holding it on longer drives.

Filled this with cold water before a long hike and it was still icy hours later, which surprised me. The lid hasn't leaked once in my bag. Only gripe is it's a bit tall for my car's cup holder.
