GET NAKED ネイキッドニュートリション シェイカーボトル（ブレンダーボール付き）- 28オンス - クリア

The 28oz size is perfect for my post-workout shakes, and the blender ball gets rid of every last lump without me having to shake it like crazy. The clear plastic is sturdy enough that I'm not worried about it cracking in my gym bag, and it's been holding up great after a month of daily use.

The lid seals tight enough that I can toss it in my gym bag without a single leak, and the 28oz size is perfect for a full scoop plus water. The blender ball still leaves a few tiny bits near the bottom, but for the price it's honestly the most reliable shaker I've owned.

The blender ball does its job—my protein powder actually dissolves without those annoying clumps at the bottom. Only wish the lid seal was a bit tighter, since I've had a few drops escape when tossing it in my gym bag.
