I am selling a brand new never used KUIU PRO 3600 Pack in the color Ash Phantom. The frame size is Tall (510-61) and the suspension system size is L/XL (34-52 inch). The hip belt and suspension system are interchangeable with any PRO or PRO LT bag from KUIU. The frame is carbon fiber and the dimensions of the pack are 27 X 13 X 14 inches. These dimensions equal a 59 liter pack. You can also adjust the bag to haul anything extra you may want to carry which will give you another 41 liters with the pack. I bought everything individually, so it comes with the bag, suspension system, frame and hip belt pouches. This system runs $642 brand new and I am asking $500 OBO for a brand new system that still has the tags on it. Buyer pays for shipping. Can take PayPal or Zelle.
