Ultralight suspension Patented Nanoweave™ technology eliminates extra stitching and bulk, while strengthening the hammock straps overall. At just 3 oz, the Python 10 Ultralight straps pack down small into their Sil/PU coated stuff sack. Secure strength The Python 10 Ultralight hammock straps are woven with Spiraline™ a technical fiber that is 15x stronger than steel. Hang your hammock from the ultralight straps safely up to 300 lb. Tree-friendly design The variable width design offsets the pressure placed on trees by widening at the end of each strap. The hammock strap's secure suspension keeps them from slipping and rubbing the bark unnecessarily.
