It combines strong cold retention with two ways to drink. | BestReviews highlights its vacuum insulation, cup-holder-friendly tapered base and dishwasher-safe construction. A recent Amazon deal put it around $15, substantially below the overall pick, though that deal price can change. | Outside Lab named this 15-ounce spill-proof tumbler its top performer and listed it at about $26. It was tested against dozens of containers, making it a lower-priced, expert-tested option rather than an untested bargain. |
| Good to know | The cup itself is not dishwasher-safe, so it needs hand-washing. | The straw lid is not fully leakproof. | Its 15-ounce capacity is small compared with the big handled tumblers. |

What matters
Match capacity and lid style to how you drink: straw tumblers are convenient, but many are not fully leakproof. Check insulation, cup-holder fit, cleaning needs and whether you need to carry it in a bag.
Who this is for
These picks are for people choosing a reusable insulated tumbler for cold drinks, coffee or commuting. If you need a cup you can toss in a bag without concern, prioritize a fully sealing lid over a straw-first design.
The picks, one by one
Best overall: Owala 40-Ounce Tumbler
BestReviews’ testing found plenty of ice remained after 12 hours, and its straw seal and separate swig opening helped control spills. It combines strong cold retention with two ways to drink. The 40-ounce version is a good fit if you want a large daily water tumbler. Reviewers liked the sturdy handle and the rubber seal that holds the straw in place. The lid also has a swig opening with a closing tab. BestReviews says the lid is dishwasher-safe, while the cup is not. Skip it if you want a compact tumbler or need a simple, fully dishwasher-safe option.
Good to know: The cup itself is not dishwasher-safe, so it needs hand-washing.
See on AmazonBest value: Simple Modern 40-Ounce Trek Tumbler
BestReviews highlights its vacuum insulation, cup-holder-friendly tapered base and dishwasher-safe construction. A recent Amazon deal put it around $15, substantially below the overall pick, though that deal price can change. It comes with a handle, straw lid and two straws, with the straw position adjustable for left- or right-handed sipping. The lid is described as leak-resistant, not a guarantee for tossing it loose in a bag. Reviewers also note its insulated design helps prevent exterior sweating. It is a strong choice for a large cold-drink tumbler at a discount. Skip it if you need a reliably leakproof bag carry.
Good to know: The straw lid is not fully leakproof.
See on AmazonCheapest that's still good: Zojirushi Stainless Tumbler SX-FSE45
Outside Lab named this 15-ounce spill-proof tumbler its top performer and listed it at about $26. It was tested against dozens of containers, making it a lower-priced, expert-tested option rather than an untested bargain. Outside’s lab used probe thermometers to track hot-water temperature hourly, with tumblers starting at 165°F and tests ending at 125°F. The SX-FSE45 has a lid designed to reduce spills and is sized more like a coffee tumbler than a big handled water cup. It makes sense for hot drinks or a smaller everyday carry. Skip it if you want a straw, handle or large 30- to 40-ounce capacity.
Good to know: Its 15-ounce capacity is small compared with the big handled tumblers.
