Thank you for viewing. This is a soft case for a Montbell bottle. It's sized to fit a 500ml bottle and can be attached to the shoulder harness of a backpack or a waist bag. Color: Black Size: 85 x 180mm Weight: 47g *Measured by us I used it for several years, but I'm selling it because I changed bottles and no longer use it. There are some scuffs as it was used attached to a backpack. Please understand that this is a used item before purchasing. No returns or exchanges, please.
