Kalenji, Decathlon’s brand for jogging and runnning, has collaborated with France’s Centre Oscar Lambret (Oscar Lambret Center) on the development of the Jogkokoon+, a sports bra specifically designed for women with breast cancer who have undergone mastectomy. Centre Oscar Lambret is the regional center for the fight against cancer of France’s Hauts-de-France region. The collaborative effort, which involved medical professionals and patients of the center, alongside Decathlon’s staff, began back in 2017, the company said. The Jogkokoon+ is made of soft fabric to limit irritation. The patients tested different fabrics and selected the one that seemed softest and most comfortable, Decathlon said. The bra is guaranteed without reinforcement, and has been certified as a medical device. The Jogkokoon+ and the Jogkokoon, which is the equivalent version without breast prosthesis, will be introduced in March. The Jogkokoon+ will exist in a black version only, and will be sold on the web at a price of €40. The Jogkokoon, in black and pink colorways, will be available both in-store and on the web at a price of €35. As part of the overall collaboration, the Decathlon Coach team and Centre Oscar Lambret have also developed a post-mastectomy workout program to help women who have undergone surgery return to sports while also limiting the risk of a relapse of the disease.
