I can’t remember if this is the 6400 or the 4800.
Purchased around Christmas of 2016 . Normal wear but completely functional. I have a large pillow stuffed inside during this photo and the snow collar is not expanded. $400 shipped.
2015 model? It is either a K2 or K2 2nd generation. The packs didn’t come in sizes. Just the belt sizes were S,M,L. Interested in the pack just want to make sure of the model? Do you still have your order/build sheet for the pack?
