I was sent the "Mommy in Training" shirt which is made of bamboo, cotton and spandex. This top is very stretchy and will fit my growing belly well (these pictures were taken at 13 weeks pregnant).
I was also sent some of the yoga capris which are so comfortable. They have a panel that can be folded down or it can be worn up over your belly. Both ways feel great. I have worn these walking a few times and love them.
The company also has some cute swimsuits available such as this Twist Front Maternity Tankini:
All of these items are very comfortable and seem to be well made. Many items are on sale for quite a good price if any of you mommies-to-be need some maternity workout clothes.
