Big weather protection in a compact package.

MSR increased the breathability of the 9-ounce E-Bivy so you can slumber soundly with minimal condensation inside this compact and ultralight shelter. A silnylon top fends off precipitation, while the DuraShield-coated bottom protects your sleeping bag from dew and frost. Those who fret over pack space can rest easy; the E-Bivy packs down to about the size of a soda can, but unpacks to a length fit for a wide range of high-loft sleeping bags. It's simple and effective, and it represents less of a burden than even your water bottle.
