Saw this today while I was looking for bareback pads online: Tough-1 Square Bareback Trail Soft Saddle - Statelinetack.com
Unfortunately I can't post a picture. Looks saddle-ish but it's made of heavy-duty polyester with "a foam cantle and swell that will offer the rider security that is not available in other bareback pads." Detachable saddle bags, D-rings to hold other accessories, seems to come in one-size-fits-"all" adult.
It's different (probably too different) ... but has anybody here ever used one?
