Ultralight Cotopaxi Travel Pack. This is the 28L size. It is unisex. It's an amazing bag, durable and fantastic for treking across country or abroad. This is great for an overnight bag. I am 5'6" and wore this while traveling in Italy for three weeks. I also used a small rolling bag along with it. I bought this brand new from REI. I used it for three weeks, and have not used it since. It does have light wear marks on the front, otherwise in excellent condition. All zippers are in excellent condition, the rain bag is still in its compartment and has never been used. All snapping clips, and adjustable straps are in excellent condition. I am not sure I will need a bag like this for a while so instead of having it sit around, I would love to see it go to a good home. I will not accept low ball offers. I will decline those offers. Serious offers only. This bag is in excellent condition, valuable, rarely goes on sale, and extremely well made. It will last a very long time. Let me know if you have questions.
