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 images, it shows considerable signs of use. The functionality is not affected, so how about it for those who want to try it out? ★I have many cycling items for sale, such as a Garmin Edge 530, a cycling drive recorder, bottle cage sets, and a bike transport bag set, so please take a look★
