This inflatable toboggan is the most comfortable 2 rider snow tube you'll find. Plastic runners on the bottom help it track nicely in all kinds of snow. Measuring 69 in. x 26 in. (deflated), there's plenty of room for 2 kids. The heavy gauge PVC material has electronically welded seams and contains special crack resistant additives that protect the tube to 25 degrees C (-13 degrees F).
