The third version of the Stow-N-Go bra is not only lighter than its predecessors, it also better incorporates its key feature—the center chest pocket—into its overall function as a bra. The cups are simultaneously connected and separated by the center pocket by a double layer of fabric increasing individual support. Plus, the main compartment has an even smaller pouch within it for organizing a number of items.

The Super Band bra has a thicker under-band that provides ample support in addition to zoned ribbing in key areas that shape a more natural cup. Its seamless design eliminates underarm chafing and its stretchy, compression-like material combined with front and back mesh details help with breathability. Thin racerback straps also put less pressure on the shoulders.

Tracksmith’s first running bra, a part of its relatively new women’s line, has an Ivy League-inspired
 look that’s simple in appearance but built for high performance. Made of a nylon/spandex blend and constructed with twin layers of fabric, this bra maintains modest coverage that can be worn by itself as a racing top. Runners who opt for light compression over support will especially appreciate this bra for its smooth, non-constricting material.

Most heavy-duty bras for A and B cup sizes feel bulky and unnecessarily padded. However, the Supernova Bra, an adidas favorite, has sewn-in padding to add light structure and flexible cross-back straps 
to lift additional weight off the chest. The padding also prevents spillage over the front of the more stylish scooped neck.
