Capacity Between Refills

Fewer trips to the tap is the difference between drinking water and meaning to.

All-Day Cold Retention

Ice that survives until afternoon keeps the last third drinkable.

Leak-Proof Travel Lid

A bottle shares a bag with a laptop, so the seal has to hold sideways.

One-Handed Sip Opening

Drinking while walking or driving should not need two hands and a twist.

Simple to Clean Daily

A vessel used every day gets rinsed every day, so wide openings win.
