STANLEY IceFlow 2.0 Flip Straw Tumbler 30 oz — Leak-Resistant Lid, Ice Lasts Overnight! $46 CAD (22% Off)

Amazon.ca currently has the STANLEY IceFlow 2.0 flip straw tumbler, 30 oz, in Champagne for $46 CAD, down from $59 — 22% off. Prime members ship free; otherwise free shipping starts at $35.

The flip straw is the upgrade that matters here: the lid seals shut, so it can go in a bag or roll around the passenger seat without spilling, and you flip and sip instead of unscrewing a cap. The base is narrower than the body so it sits in most car and stroller cup holders, and the handle clips onto a bag strap.

18/8 recycled stainless with double-wall vacuum insulation — ice is still there the next morning. 30 oz is about 887 ml, roughly half a day of water. It's dishwasher safe, though one reviewer noticed the finish fading after repeated cycles, so hand washing is safer; drops will leave dents but won't hurt insulation.

4.5 stars from 26,631 reviews, and the two things that come up again and again are cold retention and no leaks. Worth being precise: it's leak-resistant, not leakproof — tip it fully upside down and a little will seep, but sideways in a bag is fine.
