The "Hut 1" Meteor Bivy combination is the perfect solo backpacker shelter. It is roomy enough to keep all gear inside. The combination weighs approx 1.5 lbs with stakes(trekking pole optional), it is easy/quick to setup and because it is a tarp it can be pitched high for ventilation in summer heat or low to keep out the elements. It can also be pitched in more places than a typical double wall tent and is very good in extreme weather. Also note, we purchased the tarp and bivy used at less than half the new price.
