Montbell Trekking Umbrella 50 I purchased this from the official website about two years ago! I loved how lightweight it was, but I'm selling it because I got a different umbrella when I joined the company! I think it can still be used, but I'm selling it at a bargain price because it's used. Please purchase with the understanding that it is used. This is a lightweight umbrella suitable for trekking. It uses 8 ribs of 50cm carbon fiber reinforced resin, achieving a high level of both lightness and strength. Includes a storage case.
