So iLL

So iLL is an American climbing brand based in St. Louis, Missouri. Founder Dan Chancellor and his brother began it by pouring climbing holds by hand, and the name stands for Southern Illinois; the brand dates its story to 1997.

Alongside holds, volumes and training boards for climbing walls, So iLL makes climbing shoes for gym and rock climbing, including youth sizes, as well as chalk, chalk bags and clothing. Its product pages state that several of its macro hold lines are manufactured in Europe.
