Carole Martin's Active Comfort Bra delivers light to medium support in comfort thanks to two way stretch micro fibre material and racer back design. If you are looking for a bra without the rigidness and constrictive feel of a overly structured (and expensive) sports bra, this is a great bra for your favorite low impact activities like walking, cycling, skiing, gardening and yoga. Wide straps and open back reduces back strain. No need to worry about cup size; each size fits B, C, D and, even for our DD ladies. If you prefer a bra with a regular "U-back" fit instead of a racer back, check out Carole Martin's Slip-On Comfort Bra - style #7303.
