Sierra Club khaki beige lightweight Canvas Backpack Rucksack

A Sierra Club lightweight canvas type material backpack. Khaki, dark beige, or tan color (depending on how you see color) rucksack with the Sierra Club seal on the front flap (pictures do not show the color properly despite multiple attempts in sunlight and indoor light). Feels like it is made from canvas but there is no material tag and is trimmed in what is most likely black nylon. Main pocket of the bag has a drawstring closure with strap and buckle closure. 1 front pocket as well as 2 side pockets close with a strap and buckle. The back of the bag is padded for comfort and has 2 adjustable padded back straps. There is one carry pouch on the right back strap. I'm not sure if the pocket straps are made of real or faux leather 17" height, 16" Width (laying flat), 10.5" x 7" bottom, 2.5" width of back straps Inside depth (main pocket) 17", Side pouches 5.5" deep x 7.5", front pouch 7" deep x 7.5" wide Like new .Clean.
