the official store TOSUOD 550ML Cycling Bottle Features and Specifications
Built from food-grade 304 stainless steel, this bottle resists corrosion, odor, and staining so every sip stays clean and fresh no matter the conditions. The double-wall vacuum insulation locks in temperature effectively, keeping cold drinks chilled for up to 24 hours and hot beverages warm for up to 12 hours. At 550ML, the capacity hits the practical sweet spot for century rides, trail sessions, and daily commutes without adding unnecessary bulk to your kit. The leak-proof secure lid seals tight under handlebar vibration and bag pressure, so you never arrive at your destination with a soaked jersey or damp gear. A slim-profile, lightweight easy carry design slips into standard bottle cages and side pockets with zero fuss, giving you instant hydration access when you need it most.

I recommend it; the heat loss after 2-3 hours is around 20 degrees, with an outside temperature of -5 degrees. It works much better than regular thermal bottles; I recommend it.

Very nice, the spout works perfectly and kept ice water for 8 hours. Probably possible to take ice water to a long distance.
