LUNA is a bust care brand for small-busted women (AAA to C cup) that employs a patented special structure to align the 'Ω (Omega) line' through a corrective effect when worn.

The 'LUNA Natural Up Night Bra' series has sold a cumulative total of 3.5 million units, addressing the bust concerns of many customers.

Reflecting strong feedback from loyal LUNA customers, such as 'In summer, I'm bothered by the fabric on my back and sides because it's hot' and 'I want a cooler material for summer,' the company began developing a night bra with excellent breathability.

Breathability is approximately 10 times higher than conventional night bras.

Mesh material and sheer power net are used in the 'cleavage, back, and sides' areas, where women tend to sweat and feel stuffy easily. The design makes it comfortable to wear even for those who previously resisted wearing night bras due to heat. Compared to conventional LUNA bras, the LUNA Air achieves approximately 10 times better breathability, reducing stuffiness and providing a light, comfortable fit.

*Compared to our conventional product. In breathability tests based on JIS L1096, the back area showed 9.8 times improvement, and the cleavage area showed 10.3 times improvement.

It features a sheer flower design with cute, delicate lace.

Colors are available in three variations: the cool summer-like 'Ice Blue', the maturely cute 'Ice Pink', and the versatile standard 'Ice Black'.

Unique Features of LUNA Air

① Adoption of 'Sheer Power Net' over a wide area achieves approximately 10 times better breathability than conventional products. The 'Sheer Power Net', with excellent breathability, is used on the back, where heat and moisture tend to accumulate, and around the armpits and omega line, where sweat easily collects. While maintaining the compression feel that firmly supports the bust, it reduces stuffiness in the back and sides, providing a breezy and comfortable fit.

② 'Breathable Mesh Pad Pocket' & 'Mesh Pad' prevent cleavage stuffiness. To enhance breathability in the cleavage area where skin touches skin, the pad pocket also uses sheer power net. Furthermore, the 'Hand Lift UP Pad', which lifts the bust, has been changed to a mesh material to reduce overall bust stuffiness.

③ Approximately 17.7% lighter than conventional products, achieving a light fit you'll want to wear every day. Weight has been reduced from approximately 62g for the conventional 'LUNA Natural Up Night Bra' to approximately 51g, a reduction of about 17.7%. Because it's a night bra worn for long hours every night, this 'lightness' contributes to a comfortable fit.

④ [Patented] Non-wire sheet x Hammock structure. A special sheet along the omega line securely holds back, side, and belly fat into the bust. Despite being non-wire, it fits without a feeling of tightness, and LUNA's original hammock structure maintains a soft, natural cleavage in any position.

*The 'Ω (Omega) line' refers to the boundary line between the abdomen and the bust – the 'foundation of the bust'.

[Product Concept]

A night bra that achieves coolness and comfort with overwhelming breathability and cleavage-creating power.

The LUNA Natural Up Night Bra was born to address the concerns of small-busted women who want cleavage. Its patented unique structure firmly lifts and brings the bust together, creating the ideal cleavage.

Furthermore, the corrective effect when worn aligns the 'Ω (Omega) line', guiding the bust to a beautiful silhouette.

Based on the concept of 'Cleavage for every woman,' the brand has thoroughly focused on cleavage-creating power, hold power, and wearing comfort. It offers comfort you'll want to continue every day and a design that lifts your spirits.

LUNA is a bust care brand that updates 'cuteness' from the chest.
