The Woolpower Belly Warmer 200 is made for pregnant women. It provides a wonderfully soft wrap around the belly. The tube has an elasticated top and no longitudinal seams. The belly warmer is soft on the outside and terrycloth on the inside. The Belly Warmer is made from merino wool and polyamide and can be worn under or over the top all year round thanks to the temperature-regulating properties of wool.
