Owala made its name with the FreeSip water bottle, and the SmoothSip Slider brings the same attention to detail to a compact coffee tumbler. It holds 12 oz, keeps drinks hot for up to 6 hours or cold for up to 24, and has a sliding lid that's completely leak-proof.
Who it's for
Ideal for commuters and anyone who drinks coffee on the go and is tired of travel mugs that dribble or leak into a bag. The 12 oz size fits most car cup holders and coffee-maker drip trays. If you drink large iced coffees or want one bottle for water all day, a 20 to 24 oz tumbler, or Owala's FreeSip, is a better fit.
What we liked
- Completely leak-proof: the lid seals fully, so you can toss it in a bag without worrying.
- Comfortable sipping: the SmoothSip spout is shaped for an easy, splash-free sip.
- Solid insulation: double-wall stainless steel keeps coffee hot for about 6 hours and iced drinks cold for up to a day.
What could be better
- At 12 oz, it's small for large iced drinks.
- The cup itself is hand-wash only, though the lid is dishwasher-safe.
Key specs, explained
- 12 oz capacity: about one standard coffee-shop 'tall' or a single home brew.
- Double-wall vacuum insulation: hot 6 hours, cold up to 24 hours.
- BPA- and phthalate-free: backed by Owala's limited lifetime warranty.
