THERMOS Vacuum Insulated Mobile Mug FJF-580 Black FJF-580-BK 3000 I purchased this for road bike rides and used it only during the summer months for several years. It fits in a bottle cage and is very convenient to use. I liked it and used it often, so as you can see in the pictures, it shows considerable signs of use. The functionality is not affected, so how about it for those who want to try it out? ★I am also selling many cycling items such as Garmin Edge 530, cycling drive recorders, bottle cage sets, and wheel transport sets, so please take a look★
