Entrepreneur Magazine recognizes Mountain Mama founder Teresa Delfin as an inspiring mompreneur in a fun online slideshow:

When Teresa DelfĂ­n became pregnant, she didn't slow down. "I was still climbing, kayaking, riding my bike and mountain biking." But when it got cold, she couldn't find any long underwear for pregnant women. "So I started designing." Mountain Mama's line of maternity outdoor clothing launched in 2010, followed by a line of outdoor-themed onesies. The company also sponsors events, such as the Mountain Mama Road Bike Challenge.
