The IceFlow™ 翻蓋吸管壺 | 40 OZ - Stanley Create

The flip straw seals tight enough that I tossed it in my beach bag sideways without a single drop leaking, and the 40-ounce capacity got me through a whole afternoon of volleyball practice without refills. Ice stayed cold for hours, which made the long drive home way more bearable.

Been hauling this to the pool every day for two weeks now and the flip straw is the best part — it pops up one-handed even when my hands are wet. The 40 oz size means I actually finish a full jug before practice ends, which never happened with my old bottle.

The flip straw locks in place so well that I can toss it in my beach bag without a drop leaking, and the 40 oz size gets me through an entire practice without refills. Ice stayed cold for hours even in the car.
