The TreeBag Gym is an ode to NIKIN's beginnings: with it, we celebrate our very first product, once sold under the NIKIT name, on the 7th birthday of NIKIN . The TreeBag Gym has a practical outside pocket with zipper and an additional inside pocket. If you look closely, you will discover the inside label, which briefly and concisely tells the story about the product. The cords, made of 100% pure cotton, are adjustable - so that even the youngest NIKIN fans can wear it. By the way, the TreeBag Gym has also been awarded the Oekotex 100 certificate. Quite sustainable!
