This is a Gossamer Gear Mariposa 60. I purchased it at Hikers Depot a few years ago and have used it about 7 or 8 times. It's lightweight and has many pockets, making it very convenient. Size: S There is a brown stain around the waist area and some blue discoloration inside. Both are in areas that are not visible, but please check the photos. Also, there are some minor scratches here and there, so please check the photos. It can be used without any problems. Please understand that this is a used item before purchasing.
