"I have been loving this top- the fabric is weightless yet supportive. I love the practical features it has as well for sunglasses or your keys! It’s minimal coverage, but enough for a cold plunge or leisurely dip in the ocean."

"I couldn’t be happier with the Evo thong and triangle top set from Surface. I was skeptical at first and these pieces stays in place and are comfortable, which is an unlikely combo for a bikini of this size. The fit is impressive and the fabric is so soft, it's almost undetectable. I never found myself readjusting, which makes a huge difference when swimming, lounging, paddle boarding etc. The bottoms don't pinch or dig and are thoughtfully constructed with some seriously high quality materials that also dry in 3 minutes which is awesome between activities or at the end of the day. Admittedly I got a pit of sticker shock when initially looking into this item, but this bathing suit is an amazing investment piece and I have zero regrets. It's also damn cute. Cannot recommend this set more and it's amazing addition to my technical gear wardrobe."
