Lux for biG Wally
"Safer because it's a more compact, simple package and also it's less to keep track of than a 3/4 length Thermarest and a foam pad for a portaledge hanging in mid-air. It fits the frame and suspension straps snug as a bug; albeit only a mostest but nevertheless formidable step up in comfort as well as improvement in the valve technology over my trusty old model I prefer for the alpine."
