TWisted 3D®
Makes the horse run like it’s free of harness – Freedom to run fast®

The TWisted 3D is specifically designed to follow the conformation and motion of a trotting horse. Its patented Close Contact 3D™ design offers a secure, comfortable fit with no pinching. It reduces pressure across the withers, back and shoulders, prevents nerve compression, and supports natural movement.
Every horse’s withers are unique – TWisted 3D solves the problems of traditional harnesses. Every horse has an individual wither structure, and this often leads to fit and movement issues when using traditional saddle-style harnesses.
TWisted 3D addresses these challenges with its patented design that bypasses the sensitive wither area entirely and supports the horse’s natural movement.
Unlike conventional harnesses, the TWisted 3D frame is not positioned over the withers, but just behind it—at the point of the central hook—leaving the withers completely free.
Its frame technology adapts to the horse’s unique anatomy. The special Close Contact 3D™ design “hugs” the horse’s body, creating a highly stable fit.
The spinous processes and shoulder joints are free to move, allowing for a more natural running posture.
The result is a healthier horse that moves more freely and efficiently under load.
In racing, freeing the wither area improves cornering ability. The shoulders and forelimbs have more freedom, reducing even rear-leg interference.
In training, it significantly lowers long-term stress on the withers and spine.

No need for a custom fit – thanks to our unique frame technology. Thanks to its innovative frame design, the TWisted 3D saddle does not need to be custom-shaped to match your horse’s conformation.
The TWisted 3D’s features have received international recognition – including the 2023 K.G. Holgersson Innovation Award, granted by the Swedish Trotting Federation, for its contribution not only to performance but also to horse welfare.

TWisted 3D® Racelight
A purebred racing harness – with European and world records behind it


The TWisted 3D Race Light® is RW Harness’s lightest race saddle – used in setting both European and world records. It’s slimmer, lower-profile, and designed to “sink” closer to the horse. This is a true race harness with no compromises – one of the lightest in the world.
Despite its ultralight design, it sacrifices nothing in strength.
We’ve chosen the most durable and lightweight materials to meet the demands of professional competition.
TWisted 3D Race Light offers optimal support for the lightest race sulkies, and delivers outstanding performance and structural integrity even at top racing speeds.
In competitive use, the TWisted 3D RaceLight has proven its value:
freeing the withers and shoulders helps the horse move more fluidly – especially around turns on the track.
The patented Close Contact 3D™ design avoids pressure on the withers.
The unique frame technology lifts pressure off the back and shoulders and fits all horses, regardless of size or individual conformation.
No custom fitting required!
This unique structural solution adapts naturally to the horse.

RW Classic™
A timeless anatomical classic for training and racing

The RW Classic anatomical harness line, originally designed by Reijo Wahlstén in 1993, is still in production today alongside the new TWisted 3D series.
RW Classic saddles are custom-made individually to your horse’s shape, one at a time. In terms of usability and durability, RW Classic remains a top-tier choice for professionals.
RW Classic – Still top-tier in usability and durability. Our RW Classic harnesses remain at the forefront of quality in both usability and strength.
