GG Kumo 36 (2018, latest) edition https://www.gossamergear.com/products/kumo-36-superlight-backpack which comes in 15.87oz Bag + 2.22oz Pad (pad can slide into a back pocket which is quite nice). I have only had it out twice for overnights, in great condition, the only blemish is a tiny bit of webbing on the back got snagged but its not a hole or anything like that. New is $165, Would sell it for $125 shipped.
