Collar terminology in this category is inconsistent, and most of it describes either what a collar is for or what it means — rarely both. It helps to separate those two axes, because a collar can be a restraint component, a symbol, or both at once, and the words get used interchangeably.
By what they are used for
- Neck control / restraint collars. Built to hold. Wider, load-rated hardware, usually a front ring for a leash or tether. Worn during play. This is what SIN makes.
- Posture collars. Tall and rigid, designed to restrict head movement rather than to attach to anything. A specialist item.
- Day collars. Built to be worn daily in public and to pass as jewellery. Lighter, no obvious attachment point, often not removable by the wearer. Covered in full in what is a day collar.
- Fashion chokers. No function beyond appearance, and no implied meaning. Worth naming because the shape overlaps and people confuse the two constantly.
By what they signify
These terms describe a relationship stage rather than a construction. The same physical collar can be any of them.
- Consideration collar — an openly provisional stage.
- Training or protection collar — a defined intermediate stage.
- Formal or permanent collar — the committed stage, usually marked by a collaring ceremony.
Nothing about a collar's appearance reliably tells you which of these it is. Assuming otherwise is a common and occasionally embarrassing mistake.
Materials, and what each one costs you
- Leather. Traditional, softens with wear, needs conditioning and hates moisture. Marks easily.
- Microfiber. Holds its shape, wipes clean, does not absorb. No conditioning routine.
- Metal. Permanent-feeling and heavy. Comfortable only if the fit is exact.
- Fabric and chain. Light and discreet, but the hardware is usually decorative rather than load-bearing.
The material question people get wrong is buying leather for a piece worn against skin all day, then not conditioning it. See Italian leather care guide for the actual routines.
Fit
Two fingers between collar and neck is the usual guidance, and it is a reasonable floor. A restraint collar that has to be pulled tight to stay put is the wrong size. A collar should never restrict breathing, and pressure across the front of the throat is not something to work around — it is a sign to resize.
What SIN makes, precisely
Two neck control collars, both restraint collars, both from signature editions:
- PEARL — ivory Italian leather and pearl, on zinc alloy. The softest look in the range.
- KEEN BOUND — champagne-gold zinc alloy. The one that reads as a choker, and the piece most often worn openly.
Both are built to the same construction as the full sets they belong to. Neither is a day collar and neither locks — the collector case locks, the collar closes. Each single ships in its own round vault case, or comes as part of the complete BDSM set. See the rest of the BDSM gear range for the matching wrist and ankle pieces.
