Thermos 104932 Funtainer Straw Bottle, Blue, 355 ml

Product Information

Editor’s Note: We updated this guide on September 27, 2023, to add our new favorite most durable thermos, the Stanley Master Unbreakable, and averaged our temperature test findings with another year of data. The Best Thermoses of 2023-2024 Most of us bring our thermoses outdoors, so they need to be able to take a beating. Top-quality thermoses are constructed using stainless steel of some kind for the body. A stainless steel body is harder to break, especially in cold conditions. With an enormous capacity of 40 ounces, the Stanley Quencher FlowState takes care of hydration goals with just one refill. Although standing up and walking to the water cooler is a great way to get some movement in the body, let’s be real, we don’t always do it as often as we should. This takes care of always having water available near you, especially while running multiple errands or during road trips. The contents stay hot or cold for hours on end, and it holds ice cubes for at least a day due to the vacuum-insulated design. Each thermos simultaneously receives a full serving of 212-degree F water, and is then surveyed for temperature at 30 minutes, 1 hour, 4 hours, 8 hours, 12 hours, and 24 hours. While we understand that some folks recommended preheating their thermoses for maximum efficiency, we wanted to replicate the most likely scenario and poured our brew into room-temp thermoses.

Durability is one of the most important characteristics in regard to long-term use. A lifetime warranty usually indicates the manufacturing is of high enough quality that a brand is willing to insure their products for an indefinite amount of time.

True, it’s a tad heavier than some of its counterparts on the market at over 2 pounds, but there are numerous reasons Stanley has been used for generations. For one, the double-wall vacuum insulation has a time-worn groove of reliability, and in our testing was able to keep hot water at 157.5 degrees F after a full 24 hours — only 3 degrees shy of the top spot (also held by a Stanley). It should be noted that you won’t want to use a drinking straw lid for any hot liquids, as they aren’t rated as such. We also missed having the integrated cup that some of our other thermoses have but made do without it. But for an insulated vessel that’ll hold almost all of it, it’s tough to complain. During testing, this tumbler didn't leak at all. It also performed very well when it came to cold drinks, with under-40-degree temps lasting for over 10 hours.

The most noticeable design features of the massive tumbler are its handle and a tapered base that's shaped to fit into any cup holder. This means we can carry it around comfortably from our desks to the gym to our cars, where it sits comfortably during the drive. The sturdy handle especially makes it so easy to lift and carry. The lid is fitted with a reusable straw and is adjustable so left-handed people can also use it comfortably. Hate handwashing and air-drying water bottles? Us too! These are dishwasher safe, so we can finally keep our water bottles squeaky clean and not skirt around the task. If you’re looking for something that keeps your drinks well-insulated, this model boasts double-wall insulation that keeps your drink’s temperature no matter what the outside weather. This 20-ounce tumbler stands 6.88 inches high and has a 3.5-inch diameter that fits most standard-size cupholders. Hydro Flask’s tumbler cup does a great job on all fronts with its TempShield double-wall vacuum insulation. It can keep hot beverages warm for up to six hours with the lid and keeps beverages cold for up to 24 hours, something reviewers rave about. The design also prevents the tumbler from sweating, so there's no worrying about getting rings on your furniture. Renu Dhar, a personal chef, culinary instructor, and food blogger, tested the popular Stanley Quencher H2.0 FlowState Tumbler on multiple errands, road trips, and everyday journeys from her desk to the gym to her car. If you’re somewhat of a coffee snob, this 16-ounce mug elevates your coffee-drinking experience exponentially. In place of a small, sippy opening, this mug has a wide-mouth opening with a screw-on cap that allows the user to fully experience coffee and all its aromas. Plus, the opening is designed to fit the most popular manual brewing devices and all standard drippers.

The insulating capabilities of a thermos are what makes them so useful. Most on the market today will utilize vacuum insulation, but some may also use foam insulation. Vacuum insulation tends to work better than foam, making it the standard for quality thermos brands. There are many benefits of using a thermos with a straw, and some of these we have mentioned below. To make you understand how the thermos with straw is better than the ordinary one.

It’s useful for holding cold liquids for hours, and your kids won’t have to worry about opening and closing the top because it has a built-in straw. The straw makes it easy for kids to drink with no tilting necessary. The thermoses can roughly be grouped into three groups: those that were able to maintain at or about 150 degrees after 24 hours (the Stanley Classic, Stanley Master Unbreakable, and Thermos Stainless King), those that could maintain above 100 F (CamelBak MultiBev, Zojirushi SM-TA48, Hydro Flask Standard Bottle, and the Maxsos), and those that fell to room temp (the Thermos Funtainer, Stanley Titanium, Contigo, Takeya, Hydro Flask Food Jar, and the YETI Rambler Mug). Whether you’re heading out for a day of hunting, ice fishing, or enjoying the solitude of a winter trail, a warm cup of coffee or a hot lunch can make even the coldest of days feel enjoyable. High-quality insulated food and drink containers can reliably maintain the temperature of their contents for hours on end. The perfect thermos will vary from person to person, but they all have overlapping qualities that make them the ideal piece of outdoor gear.There’s also more to using titanium than the space-age cool factor: When it comes to thermal efficiency, titanium has a lower temperature coefficient of resistance than stainless steel, meaning it keeps the warmth in your drink longer. Whether or not this is worth the high dollar amount will be up to you, but the tech is undeniable. Vacuum insulation uses a double layer of material to create a space between the walls. This gap of air (the vacuum) is what prevents heat from escaping or entering. While vacuum insulation has become the gold standard in thermos technology, the nature of the double-walled construction creates extra weight. Insulated tumblers come in a wide variety of materials, including stainless steel, plastic, and even ceramic. The right material will depend on your specific needs—for example, if you'll be using it primarily for cold versus hot beverages, or if it needs to be resistant to drops and dents for families with small children. Generally, stainless steel is ideal for most situations since it is easy to clean, resistant to stains, and more insulating. Another aspect of the lid to consider is the seal and how you drink out of the thermos. If you have a food-specific thermos, consider how easy it is to pour from the opening as well.

The most popular size for the Contigo Travel Mug may seem small, but Contigo makes 16-, 20-, and 24-ounce size options. To further add to consumer design choices, Contigo gives you the option to have a handle, grip, or neither. We most appreciated the low profile of this mug when it came to commuting, where the Byron 2.0 slotted easily into any cup holder.They’re vacuum-insulated to keep food hot for up to 12 hours and cold for 24 hours. The top lid doubles as a bowl for eating, and the air-pressure-sealing lid secures the food within the thermos. With an updated design, a foldable spoon fits into the sealing lid.
