This is the Nike Swim Solid Open-Back One-Piece, a women's one-piece swimsuit designed for chlorinated water use. It features a racerback style with a teardrop-shaped open back, wide V straps, soft unpadded cups, and high-cut leg openings. The fabric is durable for extended pool sessions; note that the style runs small, so sizing up is recommended.

Product Insights

For regular swimmers who prioritize durability and natural shaping, Nike's Solid Open-Back One-Piece delivers 200+ pool hours of chlorine and fade resistance through its recycled polyester build, while soft unpadded cups provide a natural bustline. The open back and wide V-straps enable full shoulder mobility for freestyle and backstroke, and the regular bikini cut offers moderate leg coverage. However, sizing runs small—buyers must size up 1–2 sizes, even for a fit that lays straps flat, and the minimal support suits A-C cups best, making D+ busts or active swimmers seek alternative compression.

Verified claims

Sizing
Because the suit runs small, buyers size up 1–2 and Nike recommends size 36 for a size-34 sports bra.
Leg opening
Regular bikini cut yields moderate leg opening coverage.
Activity suitability
Buyers report good fit for gym swims and sauna when sized correctly.
Support
Soft, unpadded cups provide natural shaping but minimal support for D+ or active C-cup busts.
Chlorine resistance
51% recycled polyester body and polyester lining resist chlorine for 200+ hours.
Strap stability
Wide V-straps distribute tension and allow full shoulder mobility without adjustment.
Strap fit
Suit runs small; size up for straps to lay flat and feel comfortable.
Opacity
Full polyester lining keeps cups opaque when wet and after pool use.
Shaping
Unpadded cups provide natural shaping, but minimal support for C-cup and larger.
Care
Rinse immediately in cool water; press water out in a towel; air-dry flat; avoid softeners and dryers.
Fade resistance
Black color retains saturation for hundreds of pool hours.
Durability
All-polyester fabric lasts 200+ pool hours and resists fading from chlorine.
Shoulder mobility
Open back frees shoulder blades for rotation during freestyle and backstroke.

Acheter une taille plus grande, c'est bien vrai

Mona L.

Merci d'avoir indiqué d'acheter une taille plus grande. C'est vraiment ce qu'il faut faire.

Très beau avec style

Martine M.

On ne peut pas se fier à la taille, c’est fait très petit, j’ai dû prendre 2 tailles au dessus. Par ailleurs, c’est un maillot très bien fait

Nice clean classic look swimsuit

Joyce A.

Liked this swimsuit primarily for the open back; however I will have to return or exchange since the upper front is too loose. I usually wear size 10-12 in swimsuit, thus I ordered a size 12 but it is too loose.

Super

Catherine P.

Confortable, pratique
