Made for the Hottest Days.

The Solar Flare Molten Gradient Triangle Bikini captures the intensity of a solar eruption through a seamless blend of electric pink, molten orange and radiant yellow. Inspired by the colors of peak summer, it was created for those who naturally become the brightest part of every beach, festival and vacation.

Designed with an adjustable triangle top and matching side-tie bottoms, Solar Flare adapts effortlessly to your body. Whether you prefer more coverage or a bolder silhouette, its adjustable construction lets you personalize the fit while staying comfortable from sunrise swims to sunset celebrations.

Inspired by the Sun

Every color transition echoes the warmth of golden hour, glowing horizons and endless summer evenings. The molten gradient creates movement before you even take a step, transforming a timeless triangle bikini into a statement piece that feels vibrant without feeling overwhelming.

Wear it with an oversized linen shirt, relaxed trousers or your favorite beach accessories to move seamlessly between the ocean, beach clubs, rooftop pools and summer festivals.

    Disclaimers
    • Due to the double-layer construction and internal stitching, a visible stitch may appear in the crotch seam of the bikini bottom. This is a normal part of the manufacturing process and does not affect quality or performance.
    • Rinse thoroughly after each use to remove chlorine or salt residue and help extend the life of your swimwear.
This bikini is designed to move with you
adjustable where it matters,
comfortable from the first swim to the last sunset.

CARE INSTRUCTIONS

  • Rinse immediately after use — remove chlorine, salt, sunscreen and body oils to help preserve the fabric and elasticity.
  • Hand wash recommended — use cool water and a mild detergent to maintain softness, stretch and vibrant colors.
  • Avoid bleach and harsh chemicals — they may weaken elastic fibers and affect the print over time.
  • Do not tumble dry — lay flat or hang to air dry naturally, away from direct sunlight and heat sources.
  • Avoid rough surfaces — concrete, rocks and textured pool edges may cause pilling or abrasion.
  • Store completely dry — allow the bikini to dry fully before folding or storing to help preserve the fabric season after season.
Proper care helps preserve your bikini's shape,
stretch, and color vibrancy
from the first swim to every summer after.
