    Comments about Black Diamond Momentum 3S Climbing Harness:

    Being a tall, skinny guy, it's hard to find harnesses that fit right and and stay comfortable on all day wears. This is my favorite harness, it stays comfortably in place all day, even with a full load of gear on it. Highly recommended.
