I first found these in a local running attire store. I dubiously tried on the L expecting to have to upgrade to the XL (for a 34B-36C) and was COMPLETELY shocked to find the L was a perfect fit! AND this bra has a longer torso (a MIRACLE for us tall folk) so the good quality no-roll (YES, REALLY) elastic chestband is not jammed up under your chin – doesn't creep, and sits a more comfortable half-inch or so below the girls. This bra BEATS all of those fake no-roll elastic seamless stretchy bras HANDS-DOWN! I have about 5 of these now – because I have completely given up on the bra manufacturing world. I have nothing but sports bras now. I wear this bra to work, all day, on 5-10K runs; and no longer spend my entire day pulling at, adjusting, yanking or tweaking my bra! I only wish this exact bra came with/in a U-back option so I could wear it with more open-necked clothes.
