Offering for sale this brand new waterproof, roll-top backpack by Timbuk2. I never did get rid of the first one I have but have not used a backpack in years. For some reason anticipated putting out the first one to pasture but that never happened. This model is no longer in production and I haven't the slightest idea as to why they switched things up. The bag is a beast for lack of better way to describe how durable and yes waterproof it is. It has a 40-50 liter capacity. There is a compartment for a laptop and while I used mine for the gym it has more than enough room for squat shoes, belt, and 1/2 gallon water bottle. Included among the photos I've provided is a screen shot from an ebay listing in which the seller is seeking $699. Too funny!
