Introducing a NEW Posture Collar from Sinvention.  Our original Posture Collars can be a bit much for some as they are quite tall and strict so we have now added one that is less severe. 

This new Posture Collar features all the same goodness but offers just a tad less height.  We have elevated the classic design of a locking posture collar by using soft leather to improve the rolled edges. This helps to eliminate pressure point irritation and provides the wearer a more comfortable experience overall. It is constructed of thick real English Bridle Leather and is fully lined with thick soft leather. Locking post closures that pass through grommeted holes provide a secure and easy sizing solution.

Shown here in size Medium / Large in our Hellfire Edition with black and red coloured leathers.
*Please note that as of Dec 2025 the red lining leather is a brighter shade than what is shown here, the darker red is now sold out

This collar comes standard with 1 hanging ring but you can also choose 3 if you like (one center and one dee on each side of the collar).

This Posture Collar is 3.5" tall in front & 3" tall sides & 2" tall at back.

* 2 Keyed-A-like Padlocks are sold separately, see product options to add locks

We have included 2 photos of the Original Extreme Posture Collar size Med/Large for comparison.
