Snowboarding/skiing backpack and harness. This product is known well here in Alberta and is easy to look up. Has been an excellent tool to use with my children on the slopes. The pack has multiple options of where to clip on the leash depending on your use. You can even clip it to the kids board binding to pull them around the base or flats.
The built in D-Ring set up allows you to pick them up like a suitcase if need be as well. Some room for extra mitts and treats and stuff like that. Pictured here also, one of the metal rights encircling the rope that goes in the pack has come loose. Still functions well. My kids are finished with it now read about it the instructions are informative.
