Zeilako ThermoFlask 40 oz Double Wall Vacuum Insulated Stainless Steel 2-Pack of Drink Water Bottles, Midnight/Stone

Amazing - keeps cold for ages

Having just done a review of the wide mouth replacement lids (that you suck through rather than pour) felt it necessary to review the bottles themselves. Bought my first pair at Costco and they were so so useful tried to get two more but Costco don't do then now so tried and succeded with Amazon UK. More robust than plastic bottles and keep the water really cool. I use my for squash as plain water not to my liking but you do need to wash out bottle and lid frequently as the squash can leave residue which will tiant the taste, especially black currant and apple.

Bought this for my son to take to school, we have been using on trips outside home all summer. I took off the straw, and it works perfectly well and maintains the temperature for a good 5-6 hours. Easy to clean, easy to use and the lids are interchangeable. What’s not to like!

Hot water goes cold in about 3 hrs

Here's another version: I'm really impressed with the ThermoFlask Double Wall Vacuum Insulated bottles! They keep drinks hot or cold for hours, and the double pack is a fantastic value. The design is sleek, and they're easy to clean. Perfect for work, hiking, or just daily use. Great product!

muy buenos termos. duran mucho. el protector de goma es un game changer. sin el. sigue siendo 100% útil nada mas que estéticamente se ven muy avollados y suenan más duro cuando se caen. Yo sólo los uso para agua al tiempo / fría y conservan muy bien la temperatura. claro que depende de la temperatura ambiente, pero si es un ambiente templado, hielos me han durado más de 24 hrs. En climas muy cálidos de más de 30ºC, si duran a lo mucho un par de horas. AMO ESTOS TERMOSSSS <3

Fiquei impressionada com a entrega, veio bem antes do tempo e veio tudo certo. Quanto ao produto eu já conhecia e sabia é excelente.

My kids used these all the time for camp and school. I love the fact the mouth piece to drink from is hard plastic- all other similar products my kids would bite off the rubber mouth piece- with these thermos I don’t have to worry about that! - love the colours- I got 4 different ones already- I also like the rubber grip it has at the bottom of the bottle. Also I’ve kept cold water in here for 14+ hours and it remained cold. It’s a great size too- fills out 1 water bottle of fluid inside. Also very easy to add ice inside too. I’m definitely looking to buy some more of these in other colours.

Muy buena calidad, envío rápido. Cumple con las expectativas. Lo cogí para unos niños para el colegio y les ha sido muy útil.
