Leony Cut 1-Piece Swimsuit,navy blue
Filtered by reviews Loading reviews…
tiny, thick

im a UK 12.. 5"5 and read these are small so went up TWO sizes to a UK 16 and its still far too small and cuts in around the legs and arm pits.. felt very thick and restrictive and ive worn tri wetsuits. Not for me .. feel like you'd sink once it got wet!

Child sized!

Ordered medium/large, inner label says UK14. Just about got it over hips but the torso is incredibly short - I'm only 5 feet tall and the "neckline" didn't reach high enough to cover the essentials. Will be returning. Noticed on this order that there were no measured size charts for any items - makes any labelling totally meaningless.


Bought this a size up. IMPOSSIBLE to get into. Very badly designed and made. Will be avoiding this brand in future.

Thank you for taking the time to review us. We're really sorry to hear that you didn't find the swimming costume true to size. We will be sure to pass your feedback on to the brand and hope this does not put you off buying from us in the future.


If you have a larger bust this is tight to get on and quite snug at the top.

change size

If possible can i change the size to an 18 please

NABAIJI Swimsuit

Using this suit (and the shorty version) as my go to base layers, perfect under wetsuits. The swimsuits are fully lined under the heavy duty lycra. Warm and super comfy. Being a one piece, it stays in place once donned. No chafing, bunching or adjustment required. Cost a fraction of the price of specialised male ‘tri’ garments.

много трудно се облича

има подплата, която се запъва по кожата, ако е мокра след душ презрамките на гърба са съеднени прекалено нагоре и трудно се провират ръцете След трудния процес на обличане - вече всичко е наред

Selten so was schönes gesehen

Ich finde Badeanzüge haben etwas sehr ästhetisches. Und dieser sieht mit seinen beiden Farben extrem gut aus. Soweit ich es von außen beurteilen konnte war die Passform mehr als nur perfekt, für den langfristigen Einsatz sehr gut geeignet und es gab durchweg positive Kommentare. Sofern er wieder auf Lager ist, werden wir nachbestellen, da dieses Stück auf viel Gegenliebe gestoßen ist.


Passt perfekt

Additional Product Information


Main fabric: 80.0% Polyamide, 20.0% Elastolefin ; Lining: 100.0% Polyamide

Aquaresist technology

Products with AQUARESIST certification are guaranteed to deliver chlorine-resistance throughout their lifespan. They will maintain their elasticity and are UV-resistant. For these reasons, they are recommended for regular or intensive pool use.


Our engineers have developed a material made from polyamide and replaced spandex fibers with elastolefin fibers to guarantee the elasticity required for comfort. Importantly, it is also not damaged by chlorine. This PBT thread also has the advantage of being quick-drying. It only loses 3% to 4% resistance throughout its lifespan. Another feature: more stable colors even for bright colors.

Restriction on use

Not recommended for use on slides.

Product testing

The products labeled with AQUARESIST certification are tested under repeated cyclical loading in a pool of chlorinated water for 240 hours. No deterioration of elastic strength was observed throughout the test. Unlike a standard swimming product, this product retains its shape.
