I just received an email with the details on the new model. The hammock itself is lighter, losing the heavy metal buckles. The hammock also has a second layer/sleeve to slide in a pad. Spreader poles now have joint reinforcement.
they have a new fly that is rain fly on top, mosquito netting on sides and bottom that has side zippers on both sides.
seems like they have covered all the bases with their new model. now if I can sell my old one and order the new one.
