DD Hammock Brand new, unused. Price is firm. The DD Hammock Sleeve, a convenient accessory for hammock camping, not only keeps your hammock dry when not in use, but also makes it easy to roll up and pack into your rucksack or bag. Ready to deploy over your hammock in a sudden shower, just bunch it around the suspension cords. The DD Hammock Sleeve can also protect your hammock from rain if you leave it in the woods or garden, or while you're out exploring the wild. It makes rolling up and storing your hammock easier.
