Merino Wool - the healthy choice for your child and the planet. We made these smaller kids PJ's with a neck that is easier to fit over your little one's head. It expands to a larger size and is not just an elastic neck. Merino wool has plenty of highly desirable properties that make it an excellent choice for children's clothes. Our wool is made ethically in Australia using environmentally safe practices and manufactured in Vancouver. Merino clothing is completely natural and organic. We are a family run business that prides ourselves in offering Simply the best clothes for our customers. We use only 100% Organic PURE superfine MERINO WOOL that is 220 gsm (grams per square meter, or 6.6 oz/yard), which is one of the thickest Merino Fabric on the market – essential for a proper pajamas. It is naturally elastic, fitting snug every time. It is odour and stain resistant, reducing the need for frequent washing. Due to its natural qualities and benefits, including breathability and insulating capacity, Merino wool has historically been used across different seasons. All hems and bindings are double stitched for durability. Side seams are flat stitched so there is absolutely no irritation. We use silk labels so there are no itchy tags. Good length in the wrist and ankle cuffs so they can be rolled up or down for the perfect fit. ENVIRONMENTAL—Merino wool is biodegradable and pesticide free as Merino sheep only need water, air and grass to produce their soft fleece. Every year Merino sheep produce new fleece making it a completely renewable fiber. We are GOTS (Global Organic Textile Standard) approved. GUARANTEE- We stand by our product. Though we are a small family run business (wife, husband, 6 and 3 year old), we make good quality products and if there are any defects, we will happily accept returns.
