زجاجة مياه معزولة حراريًا للدراجات الهوائية

I bought this for the purpose of being able to ride in winter with a coffee, especially as places to stop are very limited at the moment, however even on a walk the drink got cold pretty quickly. The fact that the bottle gets hot shows its not insulated well. Hopefully it will keep drinks cold in the hotter months instead.

Kept water cool fir a little while despite very high temperatures. Also successfully protected the drinking nozzle from grit and water thrown up from the road.

Was reLly looking for something to keep teas hot during the winter. But after an hour it’s cold. Probably better for summer keeping drinks cold.
