Rally 蛋白質搖搖杯

I’ve been using this shaker for a week and the double wall insulation really keeps my pre-workout cold for hours. No leaks so far even when I toss it in my gym bag.

The spout pops open smoothly even mid-workout, and the double wall insulation actually keeps my shake cold until the last sip. The handle loop on the lid makes it easy to clip to my gym bag, and it hasn't leaked a drop in three weeks of daily use.

I was worried about leaks with a shaker, but this twist-on lid with the handle loop is rock solid. The double wall insulation keeps my pre-workout cold for over an hour, and the pop-open spout makes sipping easy mid-set.
