Our camouflage series river and snow tubes have a backwoods (real-tree like) camo canvas top for the 54" only. The bottom for snow tubes is an 18 oz. vinyl and for river tubes is either a canvas or vinyl choice (see selections). The snow tubes do not have an inner liner, but the river tubes due to prevent skin chafing on the rubber inner tube. The opening for the 44" tube is about 20" wide in diameter and about 12-14" deep, and the opening for the 54" tube is about 24" wide in diameter and about 16-18" deep. For snow versions, buy a cushion insert (optional - sold separately) for increased comfort. They are strong enough to hold a tractor trailer and are strong enough to pile on a bunch of people. Therefore, it would be safe to say that the 54" snow tube would hold up to 3 people (~700 lbs.) on top of each other. 2 people side-by-side riding would be best for the 54".
