1. Glass Bead Reflective Fabrics
Glass bead reflective fabrics work by embedding countless tiny glass beads into the fabric’s surface. When light from sources like car headlights or streetlamps hits these beads, it bounces back toward the source, a process called retro-reflection.
Visibility and Reflectivity
These fabrics are known for their outstanding visibility. Silver-gray versions typically reflect light at about 500 candelas per lux, while fluorescent yellow and red options can reach up to 700 candelas per lux. Generally, glass bead fabrics used in activewear deliver reflectivity values ranging from 250 to over 420 cd/lux/m², and they maintain this effectiveness even when light hits them from wider angles. This consistent performance ensures both safety and design versatility.
Comfort and Flexibility
Designed with both performance and comfort in mind, these fabrics are bonded to elastic backings – usually made of 86% polyester and 14% spandex – to allow for four-way stretch. This makes them perfect for snug activewear like yoga pants and cycling jerseys. For high-intensity workouts, perforated versions offer better ventilation, helping to keep wearers cool and prevent overheating. Many of these fabrics are also wind-resistant and water-repellent, making them a practical choice for outdoor activities in various weather conditions.
Durability and Care
Top-quality glass bead fabrics are built to last, withstanding 15 to 50 wash cycles at temperatures up to 60°C (140°F) while maintaining their reflective properties. To extend their lifespan, wash these garments at a maximum of 40°C (105°F) using mild detergents, and avoid bleach or fabric softeners, as these can weaken the bond holding the beads. Line drying is recommended because high heat from a dryer can damage the reflective layer. Additionally, avoid washing them with abrasive materials, like jeans, to prevent the beads from wearing off. This durability makes them a reliable option for activewear that demands both performance and longevity.
Best Applications
Glass bead reflective fabrics shine in activewear where visibility and flexibility are critical. They’re ideal for items like running jackets, cycling jerseys, compression leggings, and other outdoor training gear.

This reliability has made them increasingly popular in professional safety gear, such as police uniforms and high-visibility road-wear, where consistent performance in dark and rainy conditions is essential.
Another advantage is their wide-angle reflectivity, which ensures they remain bright even when light strikes them from extreme angles. However, their performance can vary depending on the orientation of the prisms. In specific conditions, testing shows that microprismatic materials can outperform glass beads by more than 50%. This combination of optical efficiency and adaptability makes them a top choice for demanding applications.
Durability and Care
Microprismatic fabrics are built to withstand tough environments, resisting wind, water, and abrasion. They are rigorously tested to ensure they can handle 7,500 bending cycles and 5,000 abrasion cycles while maintaining their reflectivity. In terms of longevity, they match glass bead fabrics, enduring 15–50 wash cycles under ISO 6330 conditions at temperatures between 105°F and 140°F.
To keep these materials in top condition, wash them with mild detergents and avoid using bleach or fabric softeners. Line drying is recommended, but if you use a dryer, remove the garment immediately to prevent heat damage. For storage, keep them below 80°F (26.7°C) with 30–50% humidity to avoid degradation.
Best Applications
Thanks to their durability and reliable performance, microprismatic materials are perfect for demanding environments where visibility is crucial. They are widely used in professional workwear for industries like construction, mining, oil and gas, and emergency response.

These materials are particularly effective in "poor sight environments" such as tunnels or low-light areas. Their wide-angle reflectivity ensures visibility from various directions, making them a lifesaver in situations where safety depends on being seen. Strategically placing prismatic elements on moving body parts – like arms, legs, and torsos – helps drivers identify pedestrians or cyclists at night. This is especially important since 75% of pedestrian accidents occur during dawn, dusk, or nighttime hours.
3. Stretch Reflective Fabrics
Stretch reflective fabrics combine high visibility with flexibility, making them perfect for activewear. These fabrics use micro glass beads bonded to an elastic base, typically made of 86% polyester and 14% spandex, allowing the material to move effortlessly with your body. The beads work on a wide-angle principle, reflecting light back to its source even when the fabric is stretched or angled sharply – ideal for activities like running or cycling. Let’s break down how these properties enhance performance.
