The Extreme has a large neoprene kneepad for comfort. It is the most comfortable tube for riding in a laying position due to its tapered profile. It is easily big enough to handle up to three large riders and has inflatable side bolsters that provide extra support when in a turn. The Extreme also has six convenient handles and two "easy-up" straps to make getting back on a cinch! The Boston valve is conveniently located under the corner of the neoprene pad. Constructed with a 30 gauge PVC vinyl bladder and an extra heavy-duty 840 denier nylon cover for maximum durability.
