Will it fit my Arabain?

BEST ANSWER: It fit my Arab nicely.
I have a very wide and no withered foxtrotter. Would this saddle work on her?
A shopper on Feb 3, 2019
BEST ANSWER: It fits my wide Quarter Horse along the back and shoulders, and is super comfortable for the rider. Problem for me is the center-fire rigging (doesn't show in the pictures). Center-fire is a good idea on many horses, but for my very short backed and wide shouldered girl, it puts the billets too far back and causes the cinch to sit at an angle instead of straight down. The width is probably good for you, but check that your mare has room on her bottom line for the girth to ride an inch or more behind where a double-rigged Western cinch would. I can't use the saddle, but it is so light and comfortable I'm holding onto it for another horse someday :-)
What kind of cinch does it use ? Wester , English , or ??
Sammi on May 19, 2019
BEST ANSWER: It has regular Western D-ring rigging (not in-skirt).
I normally use a 17" (18-19 if Australian) saddle. Would this saddle be too small? (Or is the 16" a "big" 16"?)
Alexandra C on Apr 7, 2019
BEST ANSWER: Sized like western ... Aussie saddles typically size like an English. I ride 16 western, 17 english/Aussie
this is a leather saddle? im 4'9" and ride a mustang.what size do you recommend?
A shopper on Mar 21, 2018
BEST ANSWER: This saddle is leather at the swells, jockey, and cantle. The skirt and fenders are synthetic. To determine the size of saddle you would need, the best thing to do is visit a local tack shop and try some saddles. See what sizes you feel most comfortable in. The depth of the seat, the shape and balance of the saddle can make a difference in the rider's fit as well. A half inch will make some difference. A whole inch can make a big difference.
Does this saddle come with off billet and tie strap ?
A shopper on Jan 24, 2018
BEST ANSWER: Yes, I like the nylon tie strap, it was odd because it came without any holes punched but I don't use the buckle tongue anyway, I always just tie.
What type of girth comes with it?
A shopper on Nov 19, 2017
BEST ANSWER: String type cinch and I wouldn't recommend it, I do recommend the saddle but you will be better off purchasing a different cinch.
Is this a treeless saddle? Would I need special padding ? Also are the stirrups included ?
A shopper on Aug 17, 2017
BEST ANSWER: It has a flexible tree that can fit to the contour of your horse's back, no special pad is required and it comes with the endurance stirrps
I know the jockeys and pommel are leather but what is the actual seat made of?

Tom B
Roadrunner on Oct 30, 2016
BEST ANSWER: seat, jockeys, pommel are all the same slick leather. Not padded.
Does the saddle come with a girth?
Karen M on Jul 24, 2016
BEST ANSWER: Yes, it came with a tie strap, off billet and a string cinch (girth). The billet and strap are good nylon, the cinch did not impress me, I wouldn't use it myself.
will this fit an adult?
A shopper on Jun 22, 2016
BEST ANSWER: It fits my short backed Missouri Foxtrotter very well. She is 25
does this saddle work on round quarter horses?
A shopper on Feb 12, 2018
BEST ANSWER: All horses are shaped different so you would be encouraged to consult with your local saddle fitting specialist to ensure the proper fit.
Is this saddle available in an 18 inch. Or 17 1/2 inch? Really wanting one but need one of those 2 sizes
Mickey on Jun 22, 2017
BEST ANSWER: This saddle is available in seat sizes 15 and 16 only.
