Thermos 104932 Funtainer Straw Bottle, Blue, 355 ml

Product Information

We love the flat siding, as it makes it way easier to grip, especially when by the pool or grill. This cup also comes with a spill-resistant lid that features a slide closure and a removable silicone gasket to make cleaning easier. Per the manufacturer’s recommendations, this wine cup must be hand-washed. 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. Thermos’s patented vacuum insulation keeps liquids hot or cold for 24 hours, and the bottles are designed to keep the exterior temperature lower, making them easy to hold. This also prevents the bottle from sweating when holding cold liquids in the summer months. Compared to the top dogs in our temperature test, the Stainless King only came out 10 degrees shy of the top numbers — an impressive feat. 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. 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.

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. 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. How well the tumblers prevent spills and leaks: We filled the tumblers to maximum capacity with room temperature water, sealed them, and laid them horizontally on top of a towel. Then, we inspected for leaks, noting where the leaks occurred and how much water was spilled. 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. When you drink water or any other drink with your cup, then it becomes risky and can fall on your clothes. And you can suppose what can happen when you are traveling. So, if you use a thermos with a straw can reduce the chances of the spill, and you will be hydrated without hesitation.

Design: Besides external features like different color options, we highlighted important design features—like lids that can be sealed completely without risk of spills—and noted whether we could open the lid using one hand or while wearing gloves.

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. 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. These mugs are safe for the microwave if you need to heat or reheat a beverage, as well as the freezer, so you can, for example, freeze portions of fruit in each glass. Unlike some insulated glasses, they can be washed in the dishwasher, so cleaning is easy when the party is over.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. I’ve never been one to struggle with drinking enough water but I definitely think the Quencher is helping me stay super-hydrated - and it is probably due to the straw.
