We review the Outdoor Research Advanced Bivy.  5 star!

SIZE: Single Person
INTENDED USE: Four season, single person shelter.
REVIEWED WEIGHT: 1004 Grams (bag and poles).  No poles no bag; 842 Grams

DIMENSIONS SETUP:  Length: 2.2M  Width 70cm  Interior Peak. 50cm

PRODUCT OVERVIEW:  Heavy Duty, 4 Season Bivy Bag. Designed for all weather comfort.

Anti-fungal treatment on floor. High Volume foot section so you can fit ski boot liners inside. Accommodates larger sleeping pads and bags for maximum comfort.  GORE-TEX Respiration Positive 3L upper.

TESTS CONDITIONS: -10C to +5C with multiple thunderstorms and heavy rain.


Sets up fast, throwdown setup.  free standing.
Weather proof


Condensation can be an issue when fully closed.  Better to keep some vents open.
Be cautious to not leave any objects on top fabric during rainfall. If water can pool some may seep through.

Many reviews stated poles are difficult to insert.  I did not find this to be an issue. Worked as per instructions.


No suggestions. Well designed product


A tent may be a better choice over a bivy bag in bad weather as you can keep your gear inside from the weather.   If you use a bivy bag in bad weather you will likely need a dry bag, like the OR Ultralight 55L dry sack, to protect your other gear.

Unless you are using this bag in extreme weather conditions this model may be overkill and you could consider the Helium at half the weight and much lower price. However I believe that from a durability standpoint the Advanced Bivy is the winner.

No long term yet.  No signs of wear or failure.  Good quality construction.

RATING:  5/5 . Performs as expected.
