Big Agnes bags are made without insulation on the bottom because insulation loses its warmth when compressed by your body. Instead, they feature a sleeve in the bag floor into which you slide a Big Agnes sleeping pad. The result is more warmth, less weight, improved compressibility and a sleeping pad that stays put no matter how much you move during the night. Ingenious.
