Sizing The Mosaic CTS

On the underside of each strap section, you’ll find eight clearly marked notches, each spaced 4mm apart. Trim one notch at a time, checking the fit as you go to avoid over-cutting.

Once trimmed, reattach the buckle and use the built-in micro-adjustment mechanism to fine-tune the final fit. This combination of CTS trimming and micro-adjustability ensures a secure, custom fit with a clean, professional finish - no excess, no bulk, just comfort.
