Our Picks: Best Spill Proof Insulated Cup With Straw reviews
ENCOOL 40 oz Tumbler: A Large Cup with a Flip-Top Lid
The ENCOOL is a 40-ounce stainless steel tumbler with a handle, straw, and flip-top lid. Its double-wall vacuum insulation is described as keeping drinks cold for up to 24 hours. The lid flips open for sipping and snaps shut to help contain the drink when you are moving around.
The handle and tapered shape are intended to make this large cup easier to carry and use in a car. The product description says its narrow shape fits most car cup holders, but fit can vary by vehicle. Its size may also feel bulky if you prefer a lighter, smaller cup.
Compared with the BrüMate and Ello, the ENCOOL has a straightforward flip-top approach rather than a covered straw that slides or retracts into the lid. It could suit you if capacity and a carry handle matter most. The leakproof claim comes from the product description, so it is still sensible to keep the lid securely closed and upright in a bag.
Pros:
- Large 40-ounce capacity with a handle
- Flip-top lid is described as leakproof
- Double-wall vacuum insulation is rated to keep drinks cold for up to 24 hours
- Tapered design is described as fitting most car cup holders
Cons:
- The large capacity may be cumbersome if you want a compact cup
- Its straw is not described as fully covered when closed
Verdict: Choose the ENCOOL if you want a high-capacity tumbler with a handle and a simple flip-top lid.
BrüMate Era Flip: A Covered Straw for Travel
The BrüMate Era Flip is a 40-ounce insulated stainless steel tumbler with a covered straw lid. Its SlideSeal mechanism slides open for drinking and closed to cover the straw. The manufacturer describes the lid as 100% leakproof and says its design works with cold and carbonated drinks. For carbonated drinks, the product description advises using at least half a cup of ice.
Its metal straw has a soft-touch silicone tip, and the lid parts can be removed for cleaning. The tumbler is designed with a tapered base for standard cup holders. These details make it a strong option if keeping the straw shielded between sips is a priority, though the lid has more components to take apart and clean than a basic tumbler lid.
Like other large cups, the 40-ounce size is best for someone who wants to carry more liquid rather than travel light. The leakproof claim is a notable advantage over cups described only as splash-resistant, but make sure the slide mechanism is fully closed before packing it.
Pros:
- Covered straw helps shield the drinking surface
- SlideSeal lid is described as leakproof
- Removable lid components support more thorough cleaning
- Tapered base is designed for standard cup holders
Cons:
- The lid has several parts to disassemble and clean
- Its 40-ounce capacity may be too large for some users
Verdict: Pick the BrüMate if you want a large tumbler with a covered straw and a lid designed to seal when closed.
Mfacoy Kids Tumbler: A Small, Spill-Resistant Cup
The Mfacoy is a 12-ounce stainless steel tumbler made for toddlers and young children. Its small size is intended for little hands, and its lid has a flexible, spill-resistant straw. The straw can be removed for cleaning, and the cup is described as double-wall vacuum insulated to keep drinks cold for hours.
This is a more focused choice than the adult tumblers in this lineup: it is designed for water, milk, or smoothies, and its flexible straw may be more comfortable for young children. The product information says it is not intended for hot, carbonated, or perishable liquids. It also says the cup body is best hand-washed, even though the tumbler is described as top-rack dishwasher safe.
Its spill-resistant lid should not be treated as a guarantee against leaks if the cup is knocked over or packed on its side. For an adult looking for a commuting tumbler, its 12-ounce capacity is likely limiting; for a child who needs a smaller cup, that size may be the main advantage.
Pros:
- Small 12-ounce size designed for children
- Flexible, removable straw
- Stainless steel body with double-wall insulation
- BPA-free and phthalate-free, according to the product description
Cons:
- Not intended for hot, carbonated, or perishable liquids
- The lid is described as spill-resistant, not fully leakproof
Verdict: Consider the Mfacoy for a young child who needs a small cold-drink cup, but choose an adult tumbler for larger servings or stronger leak protection.
Ello Oasis 30 oz Tumbler: A Straw That Tucks Away
The Ello Oasis holds 30 ounces and uses a twist-dial lid to retract the straw into the top. The product description says that once the straw is tucked away, the lid is leakproof and the drinking surface stays covered. That design may appeal if you want to protect the straw without removing it after each use.
The tumbler is described as keeping drinks cold for up to 24 hours. Its tapered shape is intended to fit most cup holders, and the cup is BPA-free and top-rack dishwasher safe, according to the product information. Compared with the BrüMate, the Ello’s key distinction is its retracting straw rather than a sliding cover.
The retracting mechanism is useful, but it is also a moving part that you will need to keep clean. Its 30-ounce capacity is smaller than the 40-ounce ENCOOL and BrüMate, which may make it easier to manage if you want a middle-sized cup.
Pros:
- Retracting straw tucks away under the lid
- Lid is described as leakproof when the straw is stored
- Insulation is rated to keep drinks cold for up to 24 hours
- Top-rack dishwasher safe, according to the product description
Cons:
- The twist-dial mechanism adds another part to clean
- Its leakproof claim depends on the straw being fully retracted
Verdict: The Ello Oasis is a practical choice if you want a mid-size tumbler with a straw that can be tucked away between drinks.
BJPKPK 20 oz Tumbler: A Smaller Cup with a Splash-Resistant Lid
The BJPKPK is a 20-ounce stainless steel tumbler with a straw and a clear lid. Its double-wall vacuum insulation is described as keeping drinks cold for up to 12 hours or hot for up to eight hours. The lid has a silicone seal and is described as splash-resistant, which is a more limited claim than the leakproof lids on the BrüMate and Ello.
The 18/8 stainless steel construction and smaller capacity may suit someone who wants a more compact cup for a desk or commute. The clear lid makes it easier to see the drink level, and the product description says the tumbler is dishwasher safe and fits most car cup holders.
The supplied listing marks this option as unavailable, so it may not be a practical pick unless it becomes available. Even when it can be purchased, treat the lid as splash-resistant rather than a secure choice for carrying sideways in a bag.
Pros:
- Compact 20-ounce size
- Insulation is described as supporting both cold and hot drinks
- Clear lid lets you see the drink level
- Product description says it is dishwasher safe
Cons:
- The lid is described as splash-resistant, not fully leakproof
- The supplied listing marks it as unavailable
Verdict: The BJPKPK could suit you if you want a smaller cup, but its splash-resistant lid and listed availability make it a less dependable choice for spill-prone travel.
How to Choose a Spill-Proof Insulated Cup With a Straw
Check what the lid is designed to prevent
“Spill-resistant,” “splash-resistant,” and “leakproof” do not describe the same level of protection. A lid meant to limit splashes may not be suitable for carrying a cup on its side. If you plan to put the tumbler in a bag, look for a lid that is specifically described as leakproof when fully closed, and follow its closing instructions. Even then, careful handling is wise.
Choose a straw cover that fits your routine
A flip-top, sliding cover, or retracting straw can protect the drinking end between sips, but each works differently. A flip-top is simple to open and close. A sliding or retracting design can keep the straw covered, though its mechanism may require extra attention during cleaning. If you prefer a basic straw and lid, check whether the product claims splash resistance or a sealed closure.
Match capacity to how you will carry the cup
A larger tumbler means fewer refills, but it can be heavier and take up more room. The 40-ounce options in this roundup are suited to people who want a larger drink, while the 30-ounce Ello and 20-ounce BJPKPK offer smaller adult sizes. The 12-ounce Mfacoy is designed for children. Think about how much you want to carry and whether you need to lift the cup often.
Consider insulation and the drinks you use
Insulation claims vary by product. The ENCOOL and Ello are described as keeping drinks cold for up to 24 hours, while the BrüMate is described as keeping drinks cold for 24 hours or more. The BJPKPK also lists hot-drink insulation. The Mfacoy is intended for cold drinks and is not recommended for hot, carbonated, or perishable liquids. Check the specific product guidance for the drinks you plan to use.
Think about cleaning before you buy
Straws and multi-part lids need regular cleaning, especially around seals, sliders, and moving pieces. The BrüMate lid components are described as removable, and the Mfacoy straw can be removed for cleaning. The Ello’s retracting mechanism is another area to keep clean. Check the care instructions for both the lid and cup body rather than assuming every part can go in the dishwasher.
Make sure the cup fits your car and your grip
Several of these tumblers are described as having tapered bases designed for cup holders, but “fits most” does not guarantee a fit in every vehicle. A large cup with a handle may also be harder to place in a tight console. If you plan to use a tumbler in the car, consider its base shape and size as well as how comfortable it will be to carry.
Frequently Asked Questions
Can I put a spill-proof tumbler in a bag?
Only do so if the lid is designed to seal when closed and is fully secured. A spill-resistant or splash-resistant lid may not prevent leaks if the cup is tilted or laid on its side. Follow the product’s instructions and use extra care when packing any straw tumbler.
Which option has a covered straw?
The BrüMate Era Flip has a sliding cover for its straw, while the Ello Oasis retracts the straw into its lid. The ENCOOL has a flip-top lid, and the Mfacoy and BJPKPK descriptions do not specify a fully covered straw.
Which cup is best for a young child?
The Mfacoy is the only option in this roundup specifically designed for young children. It has a 12-ounce capacity and a flexible, spill-resistant straw. Its product description says it is not intended for hot, carbonated, or perishable liquids.
Are these tumblers suitable for hot drinks?
The BJPKPK description includes insulation for hot drinks. The Mfacoy is specifically not intended for hot liquids. The supplied descriptions for the ENCOOL, BrüMate, and Ello emphasize cold-drink performance, so check each product’s directions before using it for hot beverages.
How do I clean a tumbler straw and lid?
Follow the care instructions for the specific cup. Remove any parts the manufacturer says are removable and clean around seals and moving mechanisms. The BrüMate’s lid components are described as removable, and the Mfacoy straw is removable. The Ello and other multi-part lids may need extra care around their mechanisms.
Which option is easiest to carry in a car?
The ENCOOL, BrüMate, Ello, and BJPKPK descriptions say their designs fit most or standard car cup holders. Fit depends on your vehicle’s cup holder, so a tapered base is helpful but not a guarantee. The Mfacoy is also described as fitting most car and stroller cup holders.
Final Recommendation
For a large tumbler with a straw that stays covered, the BrüMate Era Flip stands out for its sliding cover and stated leakproof design. The Ello Oasis is a good alternative if you prefer a retracting straw and a 30-ounce size. Choose the ENCOOL if you want 40 ounces and a handle, or the Mfacoy for a child-sized cold-drink cup. The BJPKPK is less suitable for bag storage because its lid is described as splash-resistant, and the supplied listing marks it unavailable.
