The top is made from Aspen Green Impetus 1.1 --- 15d x 15d silicone treated fabric that is highly
water repellent and breathable.  The bottom is ripstop --- 30d x 30d waterproof Nylon fabric that
is silicone coated on both sides.  

The bath tub floor of the Ptarmigan is unique in its construction. The one piece articulated bath
tub floor has no seams running vertical to the interface with the top fabric, which means no
seam sealing is required in the floor.  The hood portion of the Ptarmigan is also articulated in
the same fashion as the floor for improved movement, room, and comfort.  Bottom is Grey.
