I bought the water bottles. Then I found out which one I actually carry.

The score is mine, out of ten. The link is the listing I bought. I may earn a commission. You don't pay more.

• Stanley Quencher — 8/10. I bought it. It lives in the car. The ice lasts. Check price · The notes
• Hydro Flask — 8/10. Cold at 4pm. The lid does not betray the bag. Check price · The notes
• Yeti Rambler — 8/10. Heavier than it needs to be, and I still reach for it. Check price · The notes
• Frank Green bottle — 8/10. The pretty one that doesn't leak on a laptop. Check price · The notes
• Contigo bottle — 8/10. Doesn't leak in a bag. That's the test. Check price · The notes
• S'well bottle — 7/10. Looks like a handbag. Keeps water cold. Narrow mouth. Check price · The notes
