Reviewers say the Moving Comfort Juno (Est. $35) handily keeps their breasts in check during intense workouts, from running to boxing. A good pick for C to DD cups, the Juno blends compression and encapsulation for support. Women love the thick, cushioned straps that adjust from the front of the bra, while mesh zones and moisture-wicking fabric help keep things cool and dry. A sweetheart neckline, racerback and molded cups also give the Juno a bit more style and coverage than its popular sibling, the Moving Comfort Fiona (Est. $45). On the downside, the Juno can be hard to put on, and some reviewers say the fabric is too stiff and structured for smaller chests.
Women who want a high-impact sports bra that's as comfortable as possible may like Champion's The Smoothie (Est. $33). Supportive during high-impact workouts for B to D cups, the Smoothie is made of extra-soft fabric. Its tag-free, padded closure helps boost the comfort factor even more. Like the Moving Comfort Juno, the Smoothie blends encapsulation and compression with molded cups and convertible, adjustable straps, but its fabric offers a little more give -- good for yoga or other activities that require a large range of movement. Reviewers say that, unlike the Juno, the Smoothie's cups aren't quite substantial enough to hide headlights, making it a questionable choice for going shirt-free. Others complain the bra runs small.
If you're craving a little extra style during your high-impact workouts, the Adidas Supernova Racer (Est. $30) may fit the bill for up to D cups. Nice touches include crisscross straps with a keyhole, reflective stripes and mesh inserts that both look and feel cool, reviewers say. Like the Moving Comfort Juno and Champion The Smoothie, it combines compression and encapsulation to reduce bounce. Unlike those bras, the padded cups are removable, allowing wearers to customize their coverage. The Supernova Racer lacks adjustable straps and only comes in four sizes. Both of these factors can make getting a proper fit tricky, reviewers say.
