Looking for a lightweight bivy for use this fall and winter in the Sierras.
It would be used with my Versalite Super 10* down bag and a fluffy down jacket.
This is ideally for use without requiring a tarp, so I guess fully waterproof, large enough for boots etc. I have a 4 season 2-man tent so this would be for summits and solo. 5 days max. Looking at http://www.prolitegear.com/montbell_ultralight_sleeping_bag_cover.html
or there is a wide/long too.
