Hemp fabric is probably the most absorbent and ecological fabric of all. To grow hemp no pesticide nor fertilizers are necessary, it’s a very disease-resistant and undemanding strain of plants. . These extra long 2-layer hemp/bamboo inserts offer superior absorbency as well as easier washing and a shorter drying time than inserts with sewn-together layers. Simply fold the insert in half at the long end to create 4 thirsty layers of heavyweight fabric. They fit into any one-size cover and can be folded again in the front or back to provide even more layers in the wet zone. The hemp/bamboo mixture helps the insert stay soft even with repeated washing. . - Non-bleached, Non-dyed - Certified Oeko-Tex - Tested as safe for children under 3 years of age . Shrinking of hemp fabric is natural event. After washing you can stretch the insert with your hands, so it will get back to its original length.
