Size Large. Definitely used but still a lot of life left. The bottom has a few small slits and one larger 1 inch slit  that I'm sure could be patched. The top brain compartment is brand new, but a different color. The original zipper broke and this is what BD sent me as a replacement. 

Looking for $75. Would prefer pickup in Fort Collins or Boulder, CO but with ship if you pay shipping.
