The Science Behind Tan-Through Swimwear: How It Works and Why It’s Game-Changing

Tan-through swimwear uses a specially engineered micro-perforated fabric that allows approximately 50–60% of the sun’s rays to pass through, letting your skin tan evenly beneath the suit. Despite being breathable and lightweight, the material isn’t see-through—even when wet—so you stay covered while tanning more naturally. This fabric also dries faster than traditional swimwear and feels cooler in hot weather, making it ideal for sun-soaked adventures or all-day lounging.

Discover the technology behind Oluzu’s innovative swimwear and how it lets you tan through the fabric while keeping you cool and covered.

  • What is tan-through fabric?
    It’s a lightweight, micro-perforated material that allows sunlight to pass through while remaining opaque to the human eye—even when wet.

  • How does it let you tan evenly?
    About 50–60% of the sun’s UV rays pass through, allowing a natural, even tan beneath the fabric without needing to remove your swimsuit.

  • Is it see-through?
    No. Despite letting sunlight in, the unique weave keeps your body covered for full modesty on the beach or poolside.

  • Is it breathable?
    Yes! The fabric dries quickly, promotes airflow, and feels cooler than traditional materials, ideal for long days in the sun.
