The read
What's actually worth knowing.
The flip straw design means you can take a quick sip and snap it closed to prevent spills, which is more convenient than unscrewing a cap every time.
Double-wall vacuum insulation keeps drinks cold for extended periods, so it's actually useful for all-day hydration rather than just looking the part.
The narrow base fits most car cup holders, which is a practical detail if you're using this for commuting or road trips.
