True grey done right
I had been wanting just the right grey and found it in the Synergy. Anchor is true grey done right... without being light black or ashy.
Synergy leggings are the coolest slickest fabric to exercise in too.
Medium fits me perfectly. I'm 140#, 5'3" and wear a medium in Athleta and an 8 in Lu-who. (But I haven't purchased from either of those since discovering BP.)
