Our Fabrics & Technology

Protection Built Into Every Fiber

UV protection integrated into the fabric structure — not applied as a coating. Engineered in Germany, tested under the strictest conditions.

The Key Difference

Why Our Protection Never Washes Out

Many UV textiles rely on chemical coatings applied to finished fabric. These coatings can degrade with washing and wear. Our approach is fundamentally different: UV protection is the fabric.

Surface Coating
Applied after manufacturing
Dense Knit Structure
Protection IS the fabric
Conventional Approach
Coating-Based Protection
  • Surface treatment applied after manufacturing
  • Can degrade with washing and wear over time
  • Studies show coatings can lose significant effectiveness after repeated washing
VS
UVEEKAI Approach
Structural Protection
  • Protection IS the fabric — dense knit structure blocks UV physically
  • No coating to wash out — no measurable protection loss (Hohenstein Institute)
  • Tested under UV STANDARD 801 worst-case conditions

Precision-Engineered

Two Fabric Systems, One Goal

Every UVEEKAI product uses one of two high-performance fabrics, each engineered for its purpose. Both deliver UPF 80 protection — certified to UV STANDARD 801.

UV-Tech 168

For tops, long sleeves & swim shorts · 168 g/m²
UPF 80 Breathable Quick-Dry Chlorine-Resistant Salt Water-Resistant
  • 82% Polyester + 18% Elastane — structural UV protection built into every fiber
  • 4-way stretch for unrestricted movement
  • Moisture-wicking & quick-drying — ideal for active days in the sun
  • UV STANDARD 801 certified · test no. 24.1.10.0433-80-1
Engineered for maximum breathability without compromising protection.

UV-Tech 231

For leggings & long bottoms · 231 g/m²
UPF 80 Compression Shape-Retention Chlorine-Resistant Salt Water-Resistant
  • 74% Nylon + 26% Elastane — compression-grade support with full UV coverage
  • Body-contouring fit that retains its shape wash after wash
  • Chlorine & salt water resistant — built for ocean and pool
  • UV STANDARD 801 certified · test no. 24.1.10.0434-80-1
Engineered for high-performance activities where coverage and support matter.

The Reality Check

The T-Shirt Problem

Most people assume a T-shirt protects them from the sun. Research shows the reality is different — and it can get worse when the fabric is wet or stretched.

UPF
White Cotton T-Shirt Equivalent to SPF 5 sunscreen. Blocks only approx. 80% of UV.

UPF
Same Shirt, Wet Water can make cotton more transparent to UV radiation.

UPF
Stretched Sportswear Stretching can open the knit, letting UV through.

UVEEKAI Wet, stretched, after washing. Certified UPF 80.

UPF 80 — extends your skin's natural protection by 80x. The highest protection level under UV STANDARD 801, certified by the Hohenstein Institute. (Source: Crews et al. 2001, AATCC Review; Hohenstein Institute)

Dense Fabric Architecture

A precisely engineered fabric structure that physically blocks UV radiation — no chemical treatment needed. Protection that lasts the lifetime of the garment.

Salt & Chlorine Resistant

Yarn properties integrated during manufacturing. Designed for ocean and pool — fabric performance stays consistent after prolonged exposure.

No Measurable Protection Loss

No coating means nothing to wash out. The dense yarn structure retains its UV protection with proper care.
