Rosa long-sleeve open-back one-piece, black and white

Rosa is a long-sleeve one-piece in classic black with pure white sleeves and a stand collar. From the front it looks composed, with a small cut-out that frames the collarbone. Turn around and a deep U opens the back. The low leg covers about 90% of the seat, and the long sleeves keep the sun off your arms when you surf, dive or paddleboard. Elegant, without trying too hard.

Cool, breathable, quick-dry

Cool to the touch, like a light breeze. Dry to the hand about 15 minutes out of the water, so it never clings.

Chlorine-resistant, anti-odour

Stands up to pool chlorine, so fibres don't age, slacken or fade as fast with regular swimming.

Low-impact dyes that don't yellow

Colourfast to washing, sun and rubbing. Free of heavy metals, formaldehyde and azo dyes: gentle on sensitive skin.

LYCRA® shape retention

High stretch and recovery. Close to the body, and still crisp after many washes.

"So elegant on"

A really flattering design that wraps the tummy well. The seat is well covered and the gusset is wider, great for curvier figures.

"My back looks great"

The back cut-out is placed just right and gives me a lovely line. The fabric feels cool and comfortable all day: perfect for very sunny islands, covered without feeling hot.

Perfect if you like stylish suits but don't want to show too much. I wore it on a team trip to an island and my colleagues all said it looked great.

FAQ

Questions about the Rosa one-piece

Does the long-sleeve design help with sun protection?

The long sleeves and stand collar cover the arms, shoulders and neck, so less skin is exposed when you surf, dive or paddleboard. Use sunscreen on the skin that stays uncovered, including the open back.

How much does it cover?

Full coverage: a stand collar, long sleeves and a low leg that covers about 90% of the seat. The back is open in a deep U.

Does it run large?

It runs about half a size large. Take your usual size; size up for a looser feel or a C cup and above, and size down for a closer fit in training. The single-layer sleeves feel snug at first and ease with wear.

Are the cups removable?

Yes. Keep them in for shape and support, or take them out for a lighter feel. Wash them separately.

Can I swim and surf in it?

Yes. It fits close to the body, the elastic binding keeps water out and the two-layer fabric keeps its shape. For competitive racing, a dedicated racing suit is the better choice.

Is shipping included, and can I return it?

We cover original-order shipping and customs duties, and orders ship from China with tracking. Returns for a refund are accepted only for quality issues reported within 30 days of delivery. Size or style exchanges may be requested within 30 days of delivery for unworn, unwashed items with tags and hygiene liner intact.
