Sizing Made Easy


Note- If you have purchased a Bio-Bellum SPORT, no trimming or sizing is necessary, as they are on a buckle style system.

Our Bio-Bellum ORIGINALS are all trim-to-fit, meaning you can find your exact size! The surgical-grade silicone band does not have to be cut on the notch either. It can be trimmed for half sizes as well. We recommend trimming it larger than desired and going down, that way you'll still have room if you want to make adjustments. Below you will find a video describing more in detail, exactly what you need to do. However if you have any questions don't be afraid to reach out to one of our qualified team members.
