South Col Bivy Sack made by Integral Designs. Great for mountaineering or solo backpacking etc.

Long, left zip. Fully waterproof design, zips open about 1/4 of left side and across the chest. Has bug netting which also zips closed, with velcro tabs to keep it out of the way when not needed. There are no poles but it has a flexible wire stiffener to help keep it off your face. Includes the original stuff sack. Weighs about 1 lb 13 oz. Used only a handful of times, well cared for but no longer needed. Good condition, no damage or holes etc but a bit dirty in spots. Not exactly ultralight but it is pretty burly and highly durable.

Bright yellow top, black bottom. Burly nylon fabric with "Tegral-tex" 3L waterproof-Breathable top (with a soft and wicking inner layer) and coated nylon bottom.

$65 shipped within the US.
