The IceFlow™ Flip Straw Tumbler | 30 OZ - Stanley Create

Went for a long walk yesterday and this tumbler stayed ice-cold for hours, even in direct sun. The flip straw makes it super easy to drink one-handed without any spills when I toss it in my bag. Really impressed with how well the double-wall insulation holds up.

I was worried the straw might leak, but the snap-shut lid seals perfectly in my gym bag. The 30 oz is the perfect size to get me through practice without refilling.
