The unique combination of 59% merino wool and 41% organic cotton ensures the best comfort and thanks to its 100% natural fibers composition, it is suitable for the most sensitive baby skin. Merino wool is ultra-fine, supremely soft natural fiber that is breathable and helps to regulate the body temperature in both warm and cold weather. In the winter days, it absorbs the cold air and circulates the warmth. In summer days, it lets the body breathe while absorbing water from your little ones’ skin. It is also renewable and biodegradable. Thanks to its protein based composition, merino wool biodegrades after about a year in the ground.
