This is the 50 pound Dixon Roller Pack, WITH the Ski Attachment.
I have used it for a year or so and am going back the old backpack.
I love this thing but I cannot get a new backpack and not sell this one.
I have some things sewn onto mine (See picture)that I will remove.
Everything is is working order and sound. There are scratches on the frame and skid rails from pulling it on the trail. The Ski attachment has never been used.
Total value of $340.
For sale for $250.00 shipped to Cont US
