um, "Chamois" is not necessarily an animal skin. the padding or chamois in 99% of our bike shorts is some sort of polyester product.

Many women fit into men's saddles. Whether you are heavy or not does not matter; a lot of real heavy riders prefer smaller saddles, a lot of real skinny gals prefer the same... or bigger saddles. It's your bones and anatomy that matter the most in saddles, not fatty padding.

Tell us how many miles you have been riding; so we can compare to what you have done on this new saddle. Some pain and toughening of sit bones is normal.

Sitbones pain should be expected if you've never ridden very far; girlybits pain should NEVER be tolerated.

Sometimes the tiniest tweek in saddle angle will make all the problems go away. good luck.
