DIRECT ACTION DRAGON EGG MK2 backpack 25L Cordura fabric. I fell in love with this at Nakata Shoten in Ueno and bought it. The fabric is thick and seems durable enough for tough use. I've only used it once, but as you can see in the last photo, one of the buckles is damaged, possibly from bumping into something. The buckle itself still fits. It's a bit niche, but the quality is excellent. Those who like Mystery Ranch, etc., will likely be satisfied.
