This DoubleBubble pad is the evolution of the windshield reflector pad that I recommended years ago. This pad has two layers of bubble and is silvered on both sides, so it reflects 97% of your body's radiant heat back to you.

The Supershelter system contains multiple components that when used together make your hammock very warm.

#1 is for EXPEDITION, BACKPACKER, HYPERLITE and EVADER. #2 is for EXPLORER ULTRALITE, EXPLORER DELUXE and SURVIVOR. New and improved UnderCover can be installed or removed without taking down the hammock. Waterproof, windproof SilNylon UnderCover creates a trapped airspace. Contoured open cell foam pad attaches between the layers. Use an emergency space blanket on top of UnderPad. System includes UnderCover and UnderPad. OverCover is a separate accessory.  Note:  Radiant Bubble Pad is not part of this system.  The radiant space blanket shown in Tom's setup tips is not included.

#1 is for EXPEDITION, BACKPACKER, HYPERLITE and EVADER. #2 is for EXPLORER ULTRALITE, EXPLORER DELUXE and SURVIVOR.

The OverCover is uncoated 30D nylon with a breathing hole which fits over the mosquito net. It is intended to maintain warmer temperatures inside the shelter during dry, sub-freezing conditions. The OverCover is an accessory for the 4 Season SuperShelter. Condensation which may form on the inside of the breathable OverCover will wick through the uncoated nylon fabric and evaporate into the dry air moving between the OverCover and the rainfly.

#1 is for EXPEDITION, BACKPACKER, HYPERLITE and EVADER. #2 is for EXPLORER ULTRALITE, EXPLORER DELUXE and SURVIVOR.
