by Florian Oberparleiter® Many knot halters do not fit properly. That's why Florian Oberparleiter developed the Fit Knot Halter! Conventional knot halters usually do not take into account that the material stretches. A standard knot halter that fits well at the beginning can quickly become too wide. Florian's Fit Knot Halters take into account that the material stretches! They are therefore a little tighter at the beginning and develop the ideal fit with repeated use!
