Montbell Alpine Thermo Bottle 0.5L, color is dark gray. After purchasing new, I took it several times for summer mountain climbing as insurance for hydration. I haven't put my mouth on the cup or water bottle, and I haven't dropped it. Also, I only used it for water, without putting tea or coffee in it. There are some scratches due to carrying it around, so please check the photos. This is a used item, so please refrain from purchasing if you are nervous. Double-walled construction, keeps 78°C or higher, 0.5L black water bottle. - Brand: mont-bell - Model Name: ALPINE THERMO BOTTLE 0.5L - Capacity: 0.5L - Color: Black - Cap Type: Screw Cap - Structure: Double-walled - Heat Retention: 78°C or higher Thank you for viewing.
