We offer two different models, our Regular Straps and our Slim Straps. But except for the width and a distinction in the braided part of version 1 and version 2 of our Slim Straps, our straps are one size in total length. Only you, the customer, can change the length by inserting the carabiners into the braided piece where it fits you. But please insert the carabiners at least above the 4th braided point, so that there is not too much pressure on the knots at the end of the straps.
