New for 2013... the Ptarmigan has new fabric...
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 Dark Grey Impetus 1.2 --- 15d x 15d waterproof
fabric that is silicone coated one side and PU coated on the other.  This new fabric drops the
weight of the bivy by about 1 ounce.

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.

The full net hood option gives you full

or a combination of the fabric hood and

on the bottom zipper line of the fabric
hood zipper, and has a loop to pull the
netting off your face.
