Osprey 46l Porter pack. This bag is built SO well! Selling at REI for $195 now. Comfortable to carry, and can fit sooooo much (see last pic). It has compression staps and so many cool compartments to separate your items. I purchased new and never used, and I decided I need more of a rollling bag option for my trip. This bag needs its first adventure! Also, is carry on sized for most airlines! Its a grey with lime green interior. In brand new condition. Questions? Leave a comment below!
