The Serenity has a large over-sized door to make entering and exiting easy. No need to shimmy out of a long tube. Nor do you need to detach it from a cape or tarp when exiting. The ends of the Serenity are 8" tall. This effectively lengthens the floor and raises the netting off your face.
For hikers on the Appalachian Trail who spend many nights in shelters, the Serenity is the perfect companion. Since it takes up no more space than a bivy you won't be crowding out your neighbors. Yet it's easy to hang from the roof and guaranteed to keep the mice at bay.
The Serenity is the perfect mate for either the Gatewood Cape or Deschutes Tarp. Used together, the two make a great lightweight double-wall shelter. And on nice nights, simply set the Serenity up by itself and you've got a great star gazing shelter.
