Mad Rock maternity climbing harness. OS. Excellent condition only used a few times during pregnancy. Description as below. Designed in collaboration with our friends at Mountain-Mama, this is the first climbing harness in the world manufactured specifically for pregnant climbers. Designed by women for women, the harness is fully adjustable with wide, flexible webbing. Its open design throughout the midsection accommodates a growing belly without bunching or squeezing and the side webbing connects low and away from the chest to allow arms full-range motion. The "X" strap design at the mid-back supports and cradles the torso.
