Purchased at Patagonia Shinsaibashi 7-8 years ago. I haven't been able to go on long tours, so I haven't used it much, and it's in relatively good condition. I'm selling it to someone who will use it in the field. It's 40L, but it feels light on your back and doesn't hinder your movement. Perfect for spring season and for leaders. The current Snowdrifter costs over 30,000 yen. Please understand that this is an outdoor item, so no returns or refunds are accepted.
