THERMOS ALTA SERIES Stainless Steel Tumbler 12 Ounce, Matcha Green

UPDATE: After using this cup every day for one year, it’s still in great condition. It has held up nicely in the dishwasher and the lid comes apart so easily for extra cleaning. The snap sipper cover has not worn and locks in place securely, providing a tight seal. Still ⭐️⭐️⭐️⭐️⭐️. After buying many thermal cups and returning them because they didn’t stay hot long enough for me to finish drinking my coffee in about a half-hour, I’ve finally found the perfect thermal cup. The difference is the vacuum seal. Well made and sturdy; tight seal and does not leak; stays very hot for about an hour and warm for a few hours; fits nicely under my small Keurig without having to remove the bottom piece; dishwasher safe; easy to remove the sturdy lid; easy open and close sipping hole. This cup is not flimsy. Some have commented that it’s difficult to remove the lid, but if you open the sipping hole, the lid unscrews on and off easily by releasing the vacuum seal. Another feature that sets it apart is that I can brew a 12-oz cup of coffee without the water overflowing, with room to spare. I have only positive things to say about this cup. It’s perfect and far superior to the others I’ve tried, including expensive popular name-brands.

This 12 oz flask is the perfect daily companion for both hot and iced coffee. This is an amazing size to get. I’ve put the "drip-proof" claim to the test by carrying it inside my backpack, and it is truly leakproof—not a single drop escaped onto my gear. The exterior features a matte finish that provides an excellent, grippy texture, making it feel very secure in my hand. When it comes to maintenance, cleaning is a breeze because the components break down into two or three separate parts, ensuring no coffee residue gets trapped in the lid. Whether I'm keeping a brew warm for hours or enjoying a cold drink, this flask performs consistently well. At this price point, other brands won’t come close to quality of this thermo mug. Highly recommended as i went through numerous leakproof tumblers until i found the Alta Series.

Nice intermediate sized tumbler. The closing system is superior. I used to use Contigo but these always started to leak within a year. Keeps temperature well. Nice solid construction and the finish is very resilient. Have various of these.

Arrived scratched brand new in box. Not sure how that made it past quality control. Otherwise it’s a good smaller tumbler for those don’t drink 3 gallons of coffee everyday.

12 oz. Perfect for me. Stays hot

The thermos started to leak. I contacted the warranty department and they inundated me back and forth with ai messages about the problem with the product, even requesting a picture of the leak. I finally gave up and told them not to bother with my warranty request. I would never buy another Thermos product again.

LOVEEEEE. I love that it's dishwasher safe, I LOVE the size - it's perfect for my morning tea and fits everywhere perfectly (car cupholders, backpack, lunch box, anywhere). It doesn't keep it hot for too too long, but it's perfect for me (I don't like my tea scorching hot anyways). Never had an issue with leaking either. Not to mention the color is gorgeous!!

This was my second purchase of this mug. I bought it for a friend for Christmas since I loved mine so much. This mug comes apart completely to clean. The two plastic rings come off, the inside of the lid comes off. The easiest travel mug to clean ever. It keeps my coffee nice and hot for hours with no need to temper the mug first, even though that might help. Leak proof *as long as you remember to put it all back together* twice I’ve grabbed my mug and not make sure it was reassembled correctly and ended up with hot coffee all over me. I check it now and don’t assume. Great product - only complaint is - I wish it was larger. But that a personal coffee issue.

Me gustó mucho es muy practico y no tira líquidos si se cierra bien, el precio si es elevado pero creo que vale la pena

Sella muy bien solo tiene un pequeño detalle como que se cayó y se abolló un poco pero fuera de eso es un termo increible. Actualización: El segundo que pedi fue el verde, ambos estan muy lindos, el empaque del primero era mejor sin embargo llegó en mejor estado el segundo. Tienen diferente sistema de sellado, espero que el nuevo sea tan bueno como el anterior. Soy muy fan de lo mucho que conservan las temperaturas sobre todo en bebidas frias.

After a few uses I notice it has a plast8c aftertaste with hot liquids.

excelente tapa. buen tamaño para los espacios en coche y mochila. tapa anti derrame y con sello perfecto. lo puedes manipular con una mano. limpieza a mano o en maquina lava platos. color impecanle y muy bonito

يحفظ الحرارة بشكل معقول زي ماقالو ٣ ساعات بس القهوه تسرب اذا ميلته استخدمته مرتين عبى ملابسي وانا متاكد انه مقفل بشكل ممتاز لكن تجربه سيئة وماعاد بشتري من نفس الشركة
