BOA solution
Adjustable size
The size can be adjusted by using the BOA solution which is well known within the sports industry to adjust different type of shoes but also used within the medical industry for prosthesis.
The BOA is attached to the collar at the outer inside facing neck centre. When making the collar to go from large to a smaller size you simply turn the wheel and it will make the fabric contract while at the same time it forms the natural round shape the collar has when it´s closed around the neck. To go back to a larger size, you just pull the wheel upwards and the tension releases.
