Designed in a small body, but with an increased capacity, T500 offers not only an excellent squeeze as also a superb 4hour thermal capacity. T500 is quite smaller than those thermal bottles that we are used to and will be your new top accessory for this summer cycling or outdoor activities.This is the thermal bottle that everyone will desire for this summer season. Due to its clever design, you can use it as a thermal bottle to keep your beverage colder, on those hot sunny days, or use it as a standard bottle and increase the bottle capacity. This non-thermal option increases the bottle capacity to 650 ml. To use the thermal option, keep the cup and foam ? 500 ml capacity.In the thermal option, at, for example, an outside temperature of 23°C, the temperature of the liquid inside the bottle will go from 5°C to 15°C difference. This thermal capacity is provided for the interior foam with an aluminum membrane that prevents the temperature of the water change over a period of time.The protective cap of the bottle, besides the benefits of usage on a more adventurer cycle path, is also a good option for your gym sessions, long walks, or trails.
