'Spindrift Hammock Sock (newly updated version)
The Spindrift is a winter hammock sock specifically designed for our Ridgerunner series of hammocks. It’s essentially a large sack of breathable fabric that the hammock hangs inside of.  It’s used mainly in cool to cold weather to fully block the wind, and to increase inside temperatures by up to 10 deg. It is a water and wind resistant, breathable microclimate for your hammock. Although not a full substitute for a tarp, it does provide full protection on it’s own from light rain and snow. It provides enough weather protection to allow the user to use a summer tarp in winter and still be fully protected (the MiniFly for instance)
 
Updates include:
Double doors are now standard and your spreader bars now go on the outside of the Spindrift for easier access to your winter hammock sock. We trimmed the bottom portion slightly. The optional “pad zipper” now comes standard. A pad zipper on the head end cap allows for much easier pad insertion.'
