Running Martingale

Moss Rock’s Breast Collar is designed flexibility and adjustability, ensuring a perfect fit for a wide range of equines.

Constructed with 3/4" heavy-weight material, this breast collar is durable and reliable. The overlay color is 1/2" width material and sewn overtop of the base color.

If you're looking to give your horse extra comfort or a bolder look, the shoulder and wither straps can be upgraded to 1" wide material. The wider width helps distribute pressure more evenly and adds a stylish, more substantial appearance. If selected, the Overlay Color will also be widened to keep everything looking balanced and proportionate.

Snap Styles:
Both the Wither Strap and the Girth Strap come standard with a halter snap so that the breast collar is simple to attach and remove.
Tug Straps can be made with either halter snaps or scissor snaps—whichever you prefer. Scissor Snaps are often easier to use with gloves or for those with arthritic hands.

SIZING:
Arab Size: Shoulder Straps adjust from 16-23”, plus an additional 7-10" of adjustability in the Tug Straps
Girth Strap to Girth Ring adjusts from 14"-21”

Horse Size: Shoulder Straps adjust from 18-25”, plus an additional 7-10" of adjustability in the Tug Straps

Set of two.

Moss Rock's BioThane Stirrup Cages are designed to snap onto your stirrups. They are made from 3/4" BioThane, which has a shiny finish and a stiff yet flexible feel.

Carefully select your stirrup model and style, as these stirrup cages are made to order and are not eligible for exchange or return.

Currently, these are being made for limited stirrup brands and styles. If you do not see your stirrup model, please check back periodically as the lineup of stirrup styles is being expanded.

Sold as a pair/set of two. Stirrups not included.


Why the Cage Patterns are Not Interchangeable
Each cage pattern is meticulously designed to fit its corresponding stirrup size and model. This precision ensures that the snaps are accurately measured and placed to align with the top bar width of the specific stirrup. Due to this exacting design, the material and pattern offer no "give" or adjustability.

While the snaps might attach to the edge of another stirrup, the central portion—where the foot rests—could bulge excessively. This would make the cage too large, potentially compromising its safety features and overall functionality.

Using a cage pattern that does not match the stirrup model will result in an improper fit.


Why BioThane is the Best Choice for Stirrup Cages

Stirrup cages are made exclusively from BioThane rather than Beta because BioThane has a stiffer structure that holds its shape better over time. Unlike Beta, which has a softer, more flexible feel similar to leather, BioThane has a firmer composition that provides the necessary rigidity to keep the stirrup cage in place and maintain its form under pressure.

This added structure ensures that the cages don’t collapse inward or become too flexible, which could interfere with their function and safety.

The BioThane color choices available in the dropdown menu are the only colors I keep in stock for these stirrup cages. If you don’t see a specific color listed, it means I don’t have it on hand for this product.
