Weighing in as the lightest heat-trapping pad from Big Agnes, the Zoom UL Insulated Sleeping Pad lets us bring some cozy comfort into the backcountry. The innovative internal construction keeps weight and bulk to a minimum yet keeps cushy stability turned up to the max, saving grams and space in our pack while still giving us a plush, supportive sleeping surface. Equipped with two layers of reflective film, this pad shields us from the chill of frozen earth and sends our body heat right back to us.
