Size Guide

Sizing

Almost nothing in a SIN set has a size. Every cuff, collar and strap runs on an adjuster, so the same piece closes down to a slim wrist and opens out to a broad one.

The restraint sets

Wrist cuffs, ankle cuffs, collars and belts are all adjustable and are made to fit the great majority of adults without a size choice. Each product page lists the exact length of every piece, so you can check against a tape before you buy.

Not sure? Email support@sinpremium.com with the measurement you are worried about and we will tell you plainly whether it fits.
