One of the best features of a Yome is the filtered light that passes through the wall to bathe the interior. Other manufacturers offer reflective foil insulation for the walls. But to cover the walls with an opaque material would make the Yome dark, particularly in Winter when light is most welcome. Instead, we offer panels of a recycled P.E.T. dacron fiberfill insulation encased in lightweight, fire resistant, acrylic-coated polyester Odyssey fabric. These translucent triangular panels tuck behind the side wall poles thus sealing on all sides to stop airflow. Insulating in the same manner as a sleeping bag, they naturally puff out from the side wall creating several inches of insulative air space.
