The SkyLoft hammock uses lightweight aluminum spreader bars and a toggle system, which allows you to switch between "Relax" mode or "Sleep" mode, to create a hammock experience unlike any other. The SkyLoft easily packs into its own stuff sack, which also doubles as an integrated hammock pillow and two stretch nylon pockets keep all your small belonging close at hand while you stretch out in suspended comfort, and the light and breathable NewWave Nylon keeps you comfortable on even the warmest summer day.
