The development of an ultralight version of our Deluxe Hammock Chair has begun product testing. With a weight of only 6.5 ounces, it is easily carried in along on a hike even for the ounce counter. For those that are very concerned about weight, a 4.5 ounce version is also being tested. The innovative suspension system uses a whoopie sling permanently attached to a tree strap. The whoopie sling attaches by capturing a button knot on the chair. This negates the need for any knots or carabiners. This is a major improvement over the marlin spike setup we used in previous models. As testing progresses, we will provide updates and information on availability.
