Warm, cold, or maybe one of each! However you use 'em, these clever curlicues-of comfort can help ease tender breasts. Body Tubes are natural, gel-free breast packs made with a organic cotton shell, filled with all-natural flax seed.

The unique gel-free construction was designed with extra care to help reduce the risk of burns. You get two Body Tubes per box, one for each...well, boob.
