I love biking in skorts! Some of them are not designed for long distance riding so you have to check the label/description to make sure it has an appropriate chamois for what you intend to to.

I've found two that I've used for longer distances. One from REI - their Novara brand - which is ok but the chamois is a little bulky, I've biked up to 65 miles on that one. I have one from Castelli (used it for an 85 mile ride plus lots of 30-60 milers) that I got last year which I LOVE. I just received another one but am sad to discover they changed the chamois, even though they still call it the Elle Skort. The chamois is much wider and therefore doesn't work for me. Such a drag when companies change their product from year to year and you just want to get the one that works for you!

I've seen non-chamois skorts at L.L. Bean. I love their fitness skort for wearing both dressed up with tights and boots or dressed down with t-shirt and flip flops or if I'm just biking down to the store for something. Athleta also has quite a few although I haven't tried theirs.
