I demo'd a Dynamic from them. You pay shipping and they give you 3 weeks to demo it.
FWIW…I ride a Forma. I thought the Dynamic would be THE saddle because I like the shape of the Forma and figured the little padding would make it the perfect saddle, but after giving it a go, I found that the extra padding actually detracted from the saddle. When you get the Forma dialed in, it just seems to cradle you and (with a good pair of bibs) provides plenty of comfort. I just did a century last weekend on it with 6000 ft of climbing. No numbness. No discomfort. For me, the padding turned out not to be needed.
