Genuine Bradley Mountain natural ecru heavy backpack with leather straps and antiqued brass findings. It has one large outer pocket. It is stained. It could be dyed, but I like the patina and stains so I left it just as found. Someone tried washing it and I can smell fabric softener. The copper pieces that hold the leather in place have some verdigris.

It measures 18" long by 15". Great brown leather straps that stabilize the load. 

I looked for this one on their website and did not find it. Likely discontinued, but their backpacks are $289 and up new. Made in San Diego.
