Weighing 7.16 ounces, the Nomader is a silicone bottle that features a rigid plastic sleeve just big enough for you to wrap your fingers around while you’re carrying the bottle or drinking from it. Whereas other folding and collapsible bottles become flaccid as they are drained (it’s a common problem for this type of bottle and nothing to be ashamed of), the Nomader’s plastic sleeve ensures that this bottle’s structure won’t collapse in your hand as you’re drinking from it.
It has a large mouth, which makes it easy to drink from no matter whether you feel the need to gulp your drink down or sip at it. And when you’re not in the mood for either, the Lifefactory bottle has a leakproof, screw-top lid; two plastic protrusions stick out of the sides of the lid, allowing you to get a solid grip so that you can seal it up tight and then just as easily open it back up.
At 20 ounces, the Klean Kanteen Insulated Wide is 4 ounces smaller than we believe a good water bottle should be. But the ease of cleaning this bottle and its ability to keep drinks cool for hours at a time made us willing to look the other way—especially considering how much better it was at keeping drinks cold than most of the other higher-capacity insulated bottles we tested.
For the frequent flier, the Nalgene’s wide mouth means sipping can be dodgy on bumpy flights,” whereas the Klean Kanteen, her favorite of the lot, had a mouth wide enough to allow ice cubes, but narrow enough to sip without spillage.” Put it this way: Between the sport top and the bottle’s own medium-diameter mouth, you’ll probably find a comfortable way to drink from a Klean Kanteen.
At the time of this writing, Klean Kanteen offered six caps on its website with all-stainless-steel construction , a non-leakproof silicone sports spout , bamboo highlights , a growler-style swing lock , and even a sippy-cup style for handing the bottle to kids (or for rehydrating while recovering from a particularly harsh hangover).
I’m somewhat spoiled by the vacuum best insulated water bottle these days but even filled to the top with ice it seems to get warm as fast as a standard bottle in AZ. If you don’t need the extra insulation this is an awesome choice, unfortunately I bought it specifically for that and wasn’t terribly impressed with it’s ability to keep things cold.
Actually quite an old technology, double-walled vacuum insulation was invented in 1892 by James Dewar and has been in use for over a hundred years, commonly referred to as a vacuum flask” or Dewar flask.” Under this name, the technology has found itself employed in a huge range of applications in science in industry.
Regardless, it offers an exceptional value for the money, especially when the inclusion of three different lids (a screw on sport cap” with carabiner, a very useful straw lid, and a stylish stainless steel with bamboo top cap,) the FNova is a real bargain and exceptional quality considering the price.
To make matters worse, the Addison comes with a push-button lid but no way to lock it closed, and that’s a problem shared by Contigo’s Jackson Water Bottle Not being able to lock a push-button lid puts everything else riding with the bottle in your gym bag or shoulder bag at risk of getting soaked.

Despite being one degree behind first place in the cold water test, our favorite is the Klean Kanteen bottle The wide mouth of the Klean Kanteen made it much easier to fill with ice and to drink out of, and its slim design made it easy to fit in cupholders and bottle compartments in backpacks.

While the Kanteen may be tops for tap water, Broudy explained that if you’re planning on running your water through a portable purifying system, like a SteriPEN, or if you just want to have a nice big opening for dumping in some other type of liquid, the Nalgene’s wide mouth is an asset.
A convenient carrying strap means that you simply have to slide your hand in and begin drinking, taking the water bottle with you wherever you go. The 18-ounce bottle is made from an impact-resistant material that’s free from potentially harmful materials such as BPA and other toxins.
We tested it in the 20-ounce capacity, but the Klean Kanteen Insulated Wide also comes in 12- and 16-ounce sizes and can pair with a number of add-on lid options, including a redesigned sippy lid—the Café Cap 2.0 —that turns the bottle into a travel mug for hot drinks and other liquids.
Efforts are being made to recycle these plastics but that also incurs high costs as it is. One person using a stainless steel water bottle is enough to ensure that thousands of plastic water bottles do not end up in this vicious cycle that is causing harm to our environment.
After a month or so of heavy use, Wirecutter editor Brian Lam reported that his Klean Kanteen sports top was prone to leaking water, and when you’re talking about something that could well be a next door neighbor to your laptop when it’s inside your bag, that’s no good.
Additionally, as the bottle has no structure, you can expect it to flop around as you drink from it. This softness can lead to your slopping water all over yourself if you’re not careful, but using two hands to stabilize the bladder as it drains will remedy the problem.
The cap features a sealed silicone gasket that’s mated to the plastic of the lid, so nothing can get underneath it. Just toss the cap into some soapy water and scrub it with a bottle brush or throw it into the top rack of a dishwasher along with the Intak’s plastic body.I’ve looked at various insulated water bottles, however they either don’t seem friendly for little hands (like the Avex Contigo, the closest I’ve found to what I’m after) or they have a nice rubber/silicon spout/straw that is guaranteed to get chewed to bits in a day.
We filled each insulated bottle to capacity with water chilled to 45 degrees Fahrenheit, sealed it, and then checked it hourly over eight hours using a digital probe thermometer to see how well each vessel maintained the chilly temperature of the liquid inside.

Because of the wide mouth, and was afraid I would end up with ice pouring out onto my face & clothes, I got the straw cap & love it. I have found that if you just put your filtered water in then some ice – the ice will melt & will not be cold for very long.
Should you need a foldable bottle with a larger capacity, we suggest the 32-ounce Platypus SoftBottle Although it’s more awkward to drink out of than the Nomader, the SoftBottle remained watertight throughout our tests, and it collapses smaller.
That said, if you want or need to carry more water, and you want that water to be cold when you reach for it, we suggest looking at the Klean Kanteen Insulated Classic , which comes in a 32-ounce size as well as in 12- and 20-ounce capacities.
The 20-ounce Klean Kanteen Insulated Wide water bottle is designed to keep your drink cool, and it does so by sandwiching an insulating vacuum layer between two layers of stainless steel to prevent outside heat from warming up the interior.
Although all of the plastic bottles we used had markings to measure liquids on the side, the Thermos has a unique ring built into the cap ranging from 1-5 so you can track how many times you’ve refilled or used the bottle throughout the day.
