These Bamboo Cotton French Terry leggings are hand dyed in our studio with colours that are inspired by things we love in nature. The material used is soft and warm on the inside, making these pants great for layering in the colder months, but thin enough to wear into the spring. The Dino spike are just what kids love and will want to wear all the time. This material has lots of stretch to so they will move and grow with ease. The waist band is made from stretchy elastic so they pants will stay snug above your little ones hips. We use fibre-reactive dyes which are considered a low-impact dye and eco-friendly. Low impact dyes do not contain toxic chemicals or mordants (which fix the dye to the fabric), require less rinsing and have a high absorption rate in the fabric (70%). High absorption rates and a decreased use of rinse water create less waste water. We recommend hand washing in cool water and laying flat to dry. Our pants and leggings are handcrafted with love in our home studio in Chemainus, BC Canada. Material: Bamboo Cotton French Terry
