Change up for summer - fall 2014... the Ptarmigan has a different fabric bottom...
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 Gray --- 30d x 30d waterproof Nylon fabric that is
silicone coated on both sides.  The heavier silicone coated bottom fabric added a little weight,
but we cut $10 off the price.

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.
