This is a simple nylon sacoche bag. It's a collaboration product with Yuri Shikaku, and despite being very light, it feels like it has a lot of storage space. - Brand: Marmot - Color: Navy - Material: Nylon - Tags: Japanese washing instructions included I used it often for mountain climbing, but I'm selling it because I've started using another bag as my main one. It's still usable, but please be aware that there are wrinkles and signs of use. I will fold it up small and send it in simple packaging.
