The Cococho is a one-size carrier with a wide size range that's easy to adjust.
The waist belt's range in the narrow zipper setting is 27-65 inches, and with the wider zipper setting, it's 32-7 inches. The shoulder straps are difficult to measure, but the range is larger than other structured carriers, thanks to their unique structure.
BTW, we've found that "big" people tend to release the shoulder pads more
than they need... A high carrying position with the waist belt buckled at the
waist and not at the hips is always recommended.
