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

Happy Mouth bits are uniquely constructed with high tech plastics, making them soft, flexible, gentle and comfortable for your horse. The Happy Mouth Double Jointed Roller Dee has a double jointed mouthpiece providing independent action on each side of the horse's mouth.

Happy Mouth Double Jointed Roller Dee is rated 4.675 out of 5 by 40.
Rated 5 out of 5 by from Great option for head bobbing I have a young horse that head bobbed so badly sh could hardly be ridden. I tried a snaffle, double jointed Mylar with tongue relief,and a double jointed sweet metal bit with no improvement. This bit eliminated the behavior

Rated 4 out of 5 by from Liking this bit so far! I have only used this bit a handful of times, but so far so good! I transitioned my young mare from a large black rubber D-ring bit to this bit. She seems happy & comfortable with this bit - no head shaking or pulling. I recently trailered out for a ride with a friend & forgot my bridle, but thankfully, my friend had a spare in her trailer. When I used her Myler metal bit my mare shook her head quite a bit at the beginning of the ride, so I now know she prefers the Happy Mouth bit to that particular metal bit. I will keep using the Happy Mouth Double Jointed Roller Dee bit as long as it lasts & she is happy/responsive & comfortable working in it. I am only rating 4 stars so far, as time will tell if it holds up or not.

Rated 5 out of 5 by from My gelding loves this bit! Bought this to trail ride my gelding in. He loves it, carries it very lightly in his mouth. Just an overall quality item from SmartPak.

Rated 5 out of 5 by from Happy Mouth-Happy Mare W bought this bit for my daughter's new Warmblood mare. Boo is 8 years old, and had never been bitted. She accepted the Happy Mouth nicely and is learning to stop and rein with very little fuss.

Rated 5 out of 5 by from Mare LOVES this bit! Trainer recommended giving this bit a try, loaned us one during a lesson. Mare loved it enough that the trainer sent us home with hers and I immediately bought one when I got home. My daughter said it made all the difference at their first show with it. Mare was no longer heavy, did not pull and was much easier to get into her hunter frame.
