How it works
No holes. No guessing.

Size it once at home, then click it in a quarter inch at a time every day after. Here's how.

Fit it in three steps

  1. Open the clamp

    Flip open the clamp on the back of the buckle and slide the strap out.

  2. Cut to size

    Put the strap on through your belt loops, mark where it meets the buckle, and trim it with sharp scissors. Cut a little long the first time. You can always trim more.

  3. Reclamp and click

    Slide the cut end back into the buckle and press the clamp shut. From then on, push the strap in to tighten a quarter inch at a time.

Tighten or loosen any time
