Mountain Mama has Bay Area roots, so we couldn't miss the Birth and Baby Fair at San Francisco's Fort Mason Center. PlayPlanIt threw us props in their "Inspiring Products" blog:

"Finally, something for those active pregnant ladies. Mountain Mama is the world’s first technical outdoor apparel for maternity.  Founder Teresa Delfin & her proud husband were at the fair telling us about their line for pregnant women.  In addition to being eco-friendly, Mountain Mama clothes are made in US with high quality materials, designed to fit a pregnant woman’s growing body & be as adaptable as possible. Check out these convenient Trinity Pants - they had me at hello."
