Trek has a 90-day comfort guarantee on all saddles.

I tried out the Inform RL in three different widths last fall before deciding that it wasn't the saddle for me. At which point I returned the third one. By then I had lost the receipt but the LBS took it back anyway (I had worked directly with the store manager when I first bought it, so he knew I had bought it there).

I really liked the way the nose of the saddle was designed, but unfortunately it was too pear-shaped for me, which is why I returned it.
