Adidas down jacket

We bought the jacket just under two months ago, and we barely managed to wear it because my son slightly tore it—I tried to fix it, but he no longer wants to wear it (there are photos with the defect). The jacket is down, very light and warm. It covers the backside, like an extended coat. Price is 35 euros. Maybe someone with golden hands and creativity can fix it better because the jacket is practically new.
