When choosing a sports bra, think about the activity you’ll want to wear it for. For running and mountain biking you’ll need a sports bra that offers a lot of support, whilst skiing requires medium support and for yoga, a less-supportive bra in a nice, soft material will do the job. Since a sports bra sits directly against your skin, moisture-wicking material is important. It should fit snugly, but still allow you to take deep breaths without any trouble or discomfort.
