The Highlight of these hammocks comes in the form of a genuine Gore Tex top cover that features a Velcro brand closure that closes tight to provide shelter or easily opens wide for enjoyment on nice, warm days. The closures also feature side-release buckles to keep sleeping bags and blankets nestled inside for all-night camping. The toe end of the hammock includes a small opening to allow moisture to escape...this will keep your feet dry and warm. These are the nicest hammocks that we have ever made.
