The North Face Backpacking Bivy is an ideal, lightweight rain shelter for solo trips. This three-season bivy sack features a poled construction and fully waterproof shell fabric to give you a little more breathing room than traditional bivies. The fully taped bathtub floor keeps leaks from sneaking in during the night, and the high and low vents promote airflow. A side weather window lets you check outside without letting the storm in, and the color-coded poles make for a quick setup when the sky lets loose.
