Description

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.

October 24, 2006

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.

Security in an insecure world....
October 25, 2006

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.

Light, reliable alternative

I'm 5'8 and 145lbs. I've only used the bivy on several occasions thus far in rain and snow, and only in cold conditions (22F-35F.) I have backpacked with various tents and own another minimalist bivy. I like this one because of the poles and the ability to cover my head in the precipitation and cold. Since it gets cold I am already completely (head) in my sleeping bag with a small opening. I found that closing the bivy opening from 14 inches to 2 inches, provides an increase breathing warmth (good.) Like most bivys, if you close it up you'll get moist inside and 4" seemed adequate for me. I did like the unexpected foot zipper vent option for warmer months. I really can't comment on durability, but it seems well made. I removed the screen zipper for the winter (a plus) but I would take care with the zippers as they may be a source of breakdown in the future if careless. Some reviewers on other sites complain about the pole ends. There is a small section on the end of each pole which attaches with sturdy snaps to the bag (on set inside and one set outside.) I have heard people complain about the design of not being a single pole and that they can get lost in packing unpacking. I jusy remove the long section and leave the small pieces attached to the bag when packing. Makes set up easy and does not get in the way when rolling. If you had to attach the snaps each time, mud and snow might get jammed in and make it more difficult. I actually prefer the feature. Again, I own another much lighter bivvy, but this one is solid and I am confident in the backcountry with this in harsh conditions and this product seems very durable and well made for not that much of an increase in weight. I am also excited there is the screen feature for bugs in the warmer months. I would recommend this product to others.

Pros: Great design, Build quality, Ease of use, Cons: Cost
