Outdoor Research Advanced Bivy

The spacious Outdoor Research Advanced Bivy can be used in place of a single tent. It is larger than the Alpine Bivy, with more space for thicker sleeping pads and loftier bags. The patented dual-pole system can be used for increased ventilation and interior space, or left behind when weight and pack space are critical. The GORE-TEX Respiration Positive fabric allows warm moist air to escape to avoid condensation while providing supreme weather protection. A zippered vent at the base improves airflow on humid nights.

Reviews - Outdoor Research Advanced Bivy

Security in an insecure world....
The Outdoor Research Advanced Bivy really saved by butt a few times in alpine territory. From Mt. Washington, NH in the winter to the rainy season in Mexico, the Advanced bivy has protected me from the wind, the driving rain, the bugs and the snow. As an alpine climber, I appreciate the weight, as well as the versatility that the stake/guy loops provide. I never once felt as though myself or the bivy were going to fly away in the breeze. Also, I would never again buy a Bivy withough a pole that keeps the material off of my face. This is CRUCIAL and you can find this feature in almost all of the Bivy's that Altrec.com sells. Note: this bivy would be good if you feel as though you may be claustrophobic or you are a tall/large mountaineer. It has great amounts of room compared to other bivy's. A Top quality performance bivy for top proirity expeditions.

'great material' just not enough!
being in a wet country goretex is a great and needfull item unless your over 6 feet high then the bag is a waist of space well done outdoor research.
