Our camouflage series river and snow tubes have a woodland (Army) camo canvas top for the 44" 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. For snow versions, buy a cushion insert (optional - sold separately) for increased comfort. They are strong enough to hold a tractor trailer. Therefore, it would be safe to say that the 44" snow tube would hold up to 2 people (~450 lbs.) on top of each other.
