had one for 10 years its still going strong cant ride on current saddle without one, fit every saddle easily suede (which is shiney on mine now) very good for stickability
I love my heather moffat one - I get really painful seat bones riding in regular saddles, even ones that other people consider comfy (bizarre old injury!). I feel that I can relax more into the saddle and move better with the horse. Having said that, my sister hates it if i've left it on her saddle, she feels she doesn't get the same close contact with the horse (she is very small, so maybe being lifted an extra cm off the saddle does make a difference?)
