NYC-based HATCH specializes in easy, superversatile pieces that a mama-to-be will want to wear long after the baby is born. Coming in cool-to-the-touch cotton with a moisture-wicking bamboo viscose gusset, these second-skin maternity briefs have a hold-you-in double layer at the front (and a single layer at the back, so you don't feel like you're wearing a diaper).
