ALCYONE (formerly MAIA) is the racerback bra designed for shoulder mobility — a cut that frees the shoulder blades, allows for full range of motion in yoga and Pilates, and structures the back without tension. Its 280GSM Galaya Sculpt™ knit offers gentle yet supportive compression, its flat underbust band stabilizes without digging in, and its round neckline stays contained during movement, with no spillage or visible gaps. An essential piece for practices where the upper body works with a wide range of motion, from the studio to the street and urban strolls.

Fit & Size
On the model — The model is 1.75 m tall, B cup, and wears a size S.
Sizing advice — True to size. If you have broad shoulders, take your rib cage size, not your bust measurement. For a more sculpting effect, size down; for comfort during long classes, size up.
Care Instructions
- Machine wash at maximum 30°C, delicate cycle
- Mild detergent — never use fabric softener (it clogs technical fibers)

- No dry cleaning or bleach
The compression and racerback cut last two to four years with regular use, provided you follow this care routine and avoid fabric softeners or hot cycles.

Frequently Asked Questions
What is the advantage of a racerback versus a classic back?
The racerback frees the shoulder blades and allows for full arm movement without tension under the armpits. This is particularly useful in yoga (downward-facing dog, planks, vinyasa, sun salutations), reformer Pilates (scapular retraction, rowing), and swimming. A classic cut with straight straps limits this range of motion for open-shoulder exercises and can create a pressure point on the trapezius with prolonged movement.
What level of support does this bra offer?
Balanced medium-impact: the 280GSM knit compresses without underwire, the wide underbust band stabilizes, and the racerback cut prevents lateral bouncing thanks to its convergence towards the back. Suitable for yoga, Pilates, barre, dance, and moderate fitness. For long-distance running or repeated jumps in HIIT, supplement with a dedicated high-impact bra with a high neckline.
Is it suitable for larger busts?
Up to a C cup for dynamic activities, yes. Beyond that (D+), support remains adequate for gentle yoga and floor Pilates but becomes insufficient for dynamic movements. As the racerback cut offers less support than a cross-strap cut (which distributes the load over two points), we recommend a dedicated full-support bra for D cups and above, or layering two MAIAs for moderate activities.
How do I know if my size is right?
The underbust band should remain horizontal and flat at the back, without riding up or digging in. The neckline should fit without tension. The racerback straps should rest without cutting into the trapezius. If the band rides up when arms are raised, the size is too large; if it digs in or leaves a deep red mark after 5 minutes, the size is too small. Measure your rib cage cold as the primary reference.
Can it be worn alone on top, under a jacket?
Yes — this is a key use. The racerback cut is designed to be visible: paired with a fitted open jacket, an oversized blazer, or a light cardigan, it creates a clean and structured line. The fabric remains opaque and stable all day long, without strap deformation or stretching. Black, Beige, and Pink are the most versatile colors for lifestyle wear.
How do I wash a bra so it lasts?
Wash at a maximum of 30°C, inside out, in a mesh bag, on a delicate cycle. No fabric softener — it saturates technical fibers. Lay flat to dry, never tumble dry or on a radiator (high temperatures alter spandex). Avoid leaving it damp and balled up in your gym bag. By following this protocol, expect two to four years of regular use without loss of compression or support.
Does it leave marks on the skin after an hour of class?
Not if the size is correct. The underbust band is flat and wide, the racerback straps are wide and ergonomic, and the finishes are tag-free. If you see deep red marks after class, your size is too small — the compression is too strong on the rib cage. Go up a size, keeping the same rib cage as the primary reference.
Is it suitable for Lagree or reformer Pilates?
Particularly well-suited. The racerback frees the movement of the shoulder blades, essential for scapular retraction exercises (rowing, scooter, mermaid, oblique twists). The 280GSM compression stabilizes without hindering deep diaphragmatic breathing, and the knit remains opaque in stretched positions. For Lagree, it's an ideal cut to complement high-waist shorts or leggings.
Is the fabric certified free from harmful substances?
Yes. Galaya Sculpt 280GSM is OEKO-TEX Standard 100 certified, guaranteeing the absence of over 350 concerning chemical substances (heavy metals, formaldehyde, phthalates, azo dyes, alkylphenols). This is particularly relevant for an item in direct and prolonged contact with the skin of the chest, a hormonally sensitive area. The weaver is also BSCI audited.
What's the difference between this and an Alo Airlift or a Lululemon Energy?
The Alo Airlift is very form-fitting but not very compressive and easily marks the skin during long sessions. The Lululemon Energy is effective but uses a more fluid Luxtreme fabric, which is less sculpting. MAIA uses a dense 280GSM knit that combines strong sculpting support, superior opacity, and prolonged hold, plus OEKO-TEX certification which is absent from those two references — a concrete material argument beyond marketing.
