I have for sale or trade a used MR Pop Up 18. Used it for 3 seasons. Used and taken care of. Perfect day pack. This pack is a 18-21" frame, with choice of 29-34" or 34-39" waist belts. If you know about MR, you know they are awesome. This pack is no longer available new. Looking to get $200. Open to trades.
