Spin Class - What to Wear?

[indysteel]

I wear my regular cycling clothes. At least I used to... but at my new gym it's more low tech, so I will probably wear bike shorts with a sleeveless tech top, or maybe the Terry Eurohalter, which can double as a bike top, or great for any workouts.
I know I'd never just wear a sports bra with my shorts!

+1. My Y's spin room is always hot, so I sweat a ton. I typically wore a Eurohalter and bike shorts. Bring at least one water bottle and a towel.
