Which Tumbler Brand Wins?

performed very well, held everything inside the tumbler

not directly scored in the spill/splash section transcript, see corrosion/tip-over notes

claims no leak or spill, but unfortunately it does spill when tipped over and leaks pretty badly when facing upside down

vent hole prevents a complete seal in the fully closed position; spilled some water when tipped over and when facing downward

not directly scored in the spill/splash mess section transcript before the caption jumps to the next brand

manufacturer is upfront that this tumbler is not leak or spill proof; still performed fairly well with just a small amount of water escaping

kept everything inside the tumbler after tip over and when placed upside down

press on lid closed on nice and tight; did a great job of avoiding spills and splashes; also proved leak proof when gently placed upside down

claims to stop splashes but does not claim to stop leaks; performed as advertised with a small amount of water escaping during tip over and when facing downward

lid on nice and tight, properly closed; performed better than the HASLE and Klean Kanteen but not nearly as well as some of the other brands

unsealed lid, made an even bigger mess than the HASLE, worst spill result at that point

not directly scored in the spill/splash mess section transcript before the caption moves to the next brand

made quite a mess in the spill/splash test

moved into second place

performed better than average

very thermally efficient, moved into the lead

moved into the lead

performed very well

performed about the same as the Coleman

offers a great seal but not quite as thermally efficient as some of the other brands

not quite as efficient as some of the other brands

about 4 degrees warmer than the leader (Murricon)

lid does not create an airtight seal, fourth place behind the HASLE

about half a degree warmer than the HASLE; lid does a better job of sealing

described as top heavy (all the upper body weight on skinny legs)

profile favors staying upright

worst of all tumblers tested; a lot of taper on the bottom, has a nonslip silicone base so it likely will not slide if bumped but will lay over

tall and narrow profile makes it a lot more prone to tipping

best of all tumblers tested; very small taper towards the bottom and a well designed base to keep it upright

bottom is a little more rounded than some other tumblers with a similar profile

tapered quite a bit at the bottom

decent profile but the very bottom of the tumbler is rounded

worst yet at that point in the video; bottom of the tumbler is rounded, which hurt the result

not nearly as tall and narrow as Murricon, which helps this result

almost as good as the HASLE

the transcript reads 11 15.8 F, almost certainly a caption garble of 115.8 F given the phrase 'secured an ironclad lead'; this is the best heat retention result of all tumblers tested, repeated as 11 15.8 in the closing recap as well, so it is flagged rather than fully corrected since it is the same garbled form repeated rather than two independently-worded confirmations

moved into second place behind Murricon

performed a lot better than average

performed very well at holding heat as well as cold

the transcript reads 9.8 F on first mention and 10.8 F in the closing recap; both are almost certainly garbled versions of about 109.8 F, since Tervis is stated to move into second place right at 100 F behind this brand, and Coleman is stated to be about 22 degrees cooler than it at 87.7 F (87.7 + 22 = 109.7), two independent cross references that agree closely, so this value is corrected to approximately 109.8 F per the two-independent-checks rule, with the original garbled strings preserved here

does not hold heat quite as well as the Stanley

lid offers a really good seal

sealed lid performed about the same as the Juro

rim is not as well protected from cold as the CamelBak, which hurt performance

struggled in this test, about 22 degrees cooler than Murricon

unsealed lid (like the HASLE) hurt performance

sealed lid helped quite a bit

the transcript reads 156.25 1 F, an ambiguous garble; kept as transcribed rather than guessed since the intended value is not clear from context

screw on lid designed to take a licking and keep on ticking; a small amount of water may have escaped but the lid is still as good as new; called out with Tervis as one of the two best performers (rating of 1) in this test

survived the head on collision with the floor without losing its top; only a very small amount of water escaped and the lid survived without damage; called out with Iron Flask as one of the two best performers (rating of 1) in this test

had already lost some water in the prior tip over test; spilled pretty much everything out after hitting the floor; the lid itself survived without damage

lid was not able to stay attached to the tumbler, but the lid itself survived without damage

lid did a decent job containing water in the tip over test, but the lid came off the tumbler on impact and the lid itself experienced quite a bit of damage; one of the four tumblers called out for significant lid damage in this test

press on lid popped off after impact, but the lid itself held up fine with no damage

flip top totally flipped out from the impact but contained most of the water, and the lid itself survived without damage

lid held most of the water in but experienced a pretty bad crack from the impact; one of the four tumblers called out for significant lid damage in this test

held on to its top after impact but leaked a little more water than the Iron Flask; no damage to the lid

lid stayed on the tumbler but moved out of the fully seated position and leaked out several ounces of water; no visible damage to the lid

lost its top from impacting the floor, but no damage to the lid itself

lid stayed on the tumbler but did break; the tumbler also leaked some water onto the floor

lid broke from the impact, worst lid durability result of all tumblers tested

will hold about 20 oz without the lid, but that is about all the room available

came up about half an ounce short

pretty much maxed out, but a couple of sips in the lid should fit

easily held 20 oz with plenty of room to spare for the lid, best result of all tumblers tested

plenty of space for 20 oz, lid installed without creating a spill

came up about a half ounce short

also came up about half an ounce short on space

a little more capacity than the Klean Kanteen but not enough to install the lid with 20 oz

out of space a little early at around 19 and a half oz

came up just a little bit short

holds 20 oz but there is not enough space to also install the lid

came very close to 20 oz but came up just a little short

holds 20 oz but some of the contents must be sipped before the lid will fit

flip top as solid as iron, hard to open with one hand, 3.72 lb of force

about half a pound of force to open, easy to open

slider is very easy to open, only a quarter pound of force

can be opened with one hand but takes quite a bit of effort, 3.87 lb of force for the sliding lid cover

narrow and easy to grip with one hand, but the slider is difficult to work with, 2.7 lb of force to slide

innovative and user friendly sliding lid cover, takes less than a pound of force to slide

flip top, 1.22 lb of force according to the scale

flip lid cover is pretty easy to work with; unlocked at three quarters of a pound, the best result at that point in the test

slides freely once moving, but takes 3.25 lb of force to get the slider to begin sliding

takes a little bit more effort to open than the Tervis; about a pound of force to slide the slider

skipped this test since the lid remains open

lid pops off before the flip lid opens, needs both hands; 4.78 lb of force to open

skipped this test entirely since the lid cannot be closed

performed very well, just one little spot of rust

a few areas of rust beginning to form, performed about the same as the RTIC-branded travel mug entry; the stated biggest downside of this tumbler is being a little more susceptible to corrosion than some of the other brands

performed extremely well, no visible rust

just a few spots of rust, better than average

performed very well, no visible rust on the inside or outside

quite a bit of corrosion, but not quite as bad as the HASLE or Juro

performed better than the HASLE and the Juro, but not quite as well as Murricon or Klean Kanteen

quite a bit of rust on the inside and outside of the tumbler

quite a bit of oxidation compared to most of the other brands

performed very well, just a couple of spots where rust is just beginning to form

quite a bit of oxidation, not dishwasher safe

not corrosion resistant, quite a bit of rust already formed; supposed to be hand washed only
