We're bringing you this product at the lowest price allowed by the manufacturer so you won't find it cheaper anywhere else. This also means we can't apply any further discounts or promotions.

As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Why We Love This

The Happy Mouth Mullen Mouth King Dee has an inner core of twisted wire for more flexibility. All cheeks are stainless steel. 5", 5 1/2", 5 3/4". 20mm thickness.

    Happy Mouth Mullen Mouth King Dee is rated 4.5 out of 5 by 24.
    Rated 4 out of 5 by from Great Bit but not the one. :( This bit gives a steady gentle pressure while the Dee rings don't pinch and help with lateral steering. It is very gentle but I needed something even softer. I will use this bit later when my horse adjusts.

    Rated 4 out of 5 by from Quality Bit I purchased this bit because my Mares mouth is on the larger side. This was one of the few bits with size options. She's also transitioning from a hackamore to a bit, so I wanted something a little mild. I was impressed with the feel of the bit in my hand. Very nice quality steel, and it really smells of apple. My mare took to it nicely, and overall I'm satisfied with it. I only didn't rate it higher because it's unclear as to what material the bit is made of. I prefer more transparency in product ingredients for any safety concerns I may have.

    Rated 2 out of 5 by from Not what I was lookin for I had hoped this bit would be softer more flexible plastic coating like the nathes but I was not. Very hard, rigid, and not what my horse was liking. The coating extends up the sides of the D a bit which I felt like distracted from the overall impression. I liked the King Dee style better for aesthetics but this would keep from pinching corners. Just not what I was looking for and thanks to smartpak a free return.
