"I knew this splurge would be worth it, since it's really a three-in-one deal, and the Flux Top ($148) hasn't disappointed. It's an elegant crop top that pair flawlessly with high-waisted pants, but it's for me it's mostly a ridiculously comfy sports bra that doubles as a bikini top. Yep. It's wicking fabric makes for one fast-drying swimsuit top that provides ample coverage and support for workouts too. It's performed beautifully in yoga flow (think lots of jumping back into chaturanga), mega Reformer sessions, and vigorous studio cycling classes. And the open back and straps look so cool when worn under a flowy tank top with cut outs. Since it so multi-functioning, I have found it's perfect for travel." — Susi May, senior content director
