Which classes are not heated?

Ra Vinyasa Level 1, Ra-storative, Yin Stretch, Meditation, Prenatal, and Little Ra-scals yoga classes are not heated.  Intro to Ra Vinyasa Level 2 is a nice introduction to heated classes as it is gently heated.  The hottest classes we offer are Hot Ra 1, Hot Ra 2, Ra Strength, and Ra Vinyasa Level 2.  Our class schedule (under the "Classes" tab at the top menu) provides a feature through which you can filter classes based on the desired temperature range.
