just an fyi, i am a dude - 5'10" 185lb and i ordered the women's serfas dual density back in april 2010

i've ridden this since then and it is super comfy. doesn't look wide like a woman's saddle which is why i bought it, but it works great. i've ridden 40 miles in a day - which is nothing crazy, but a decent amount for a casual rider like me, and my bum never felt uncomfortable. for 38 bucks i am very happy. read a lot of reviews before i ordered it, and it paid off.
