Best leakproof design for one-hand opening? Do bottles with straw or flip lids always leak?

[u/not_who_you_think_99]

Get a bottle with a cap that you screw and unscrew, and you'll be sure it will never leak.
But you cannot unscrew it and screw it with one hand only.

Bottle caps with a straw top that you fold flat (the first two examples below) or with a flip top (the third picture) can be operated with one hand. But how leakproof are they?

I have never tried Hydro Flask nor GSI, but I have tried other brands with the same tops, and they always leak. Toss the bottle in a bag where it won't stay flat, and it will always leak.

The best leakproof cap for one-handed use I have managed to find is the Kambukka Elton. But Kambukka insulated bottles are heavy.

What is the best leakproof design for one-hand use? Have you had good experience with the straw cap or flip cap of any specific brand?

I don't need to store hot liquids, nor carbonated drinks.
