Easy-On Support Running Bra (D-J) ($63, originally $70)
This bra has a fully open back, which means it's breathable. It also has a very soft fabric considering how technical it is. This bra stayed in place and was comfortable against my skin during a long run. This bra is designed for larger cup sizes and is available in sizes 28D–40J. For smaller sizes, go for the Original Support Running Bra ($49, originally 70) instead.
