Outdoor Research Aurora Bivy The Outdoor Research Aurora Bivy helps you sleep soundly and comfortably through the night. This bivy is a great alternative to traditional tent systems as it keeps you protected through all-weather conditions without you having to carry around any extra weight. The bivy features stake loops, making it very easy to assemble. There is a small internal mesh pocket where you can place your keys, and other small items so they are easily accessible when you need them urgently. The 3-layer GORE-TEX material allows you to breathe comfortably, and at the same time manages condensation and deflects rain and snow. The seams are fully taped to prevent any water from seeping in and damaging the bivy. The Outdoor Research Aurora Bivy is ideal for sleeping in the warmth under the stars.
