Ultralight suspension The Roo Single Ultralight hammock is suspended by our secure, ultralight toggle-and-loop system. The toggles provide a lighter weight alternative to heavier carabiners, and integrate with traditional straps and whoopie slings. Breathable comfort Levitas™ 20D nylon ripstop fabric offers an ultralight, breathable alternative to heavier hammock fabrics. A DWR coating protects the ultralight hammock from rain and moisture, while still letting you catch the breeze. Compressed packing When the Roo Single Ultralight is unfurled, it provides a comfortable berth for overnight camping. Packed down, the hammock becomes truly pocket-sized in its Sil/PU coated stuff sack.
