Fully adjustable to fit your horse like a glove. Scissor snaps at both shoulders make for easy on/off. Optional Over the Wither/Neck Strap also available -- this is completely removable piece that goes over the horse's neck and keeps shoulder straps from hanging too low. Choose a Slide Over Attachment if using with a girth without dee rings or try our hand girth loop. This time-saving device stays on girth and provides a dee ring which you can snap the breast collar onto when tacking up. The girth loop works for any style girth.
