BMI system

Revolutionary size adjusting system by SINGING ROCK.

BMI is abbreviation of Body Mass Index.
You can easily adjust free end of your waist belt strap and fix it in the right position and minimize so called “sticking out” of padding (and sometimes the first gear loop in the line as well).

Suitable for situation as losing or putting on your weight, putting more dresses or changing of your climbing seasons. The best position is when buckle lies on padding and BMI system doesn’t allow gear loops to get out.
