💡 Tip: Be careful when comparing the four technical T-shirts in this family: the single-colour ones (305602 short sleeve and 305604 long sleeve) are class 2, and the two-tone ones (305506 short sleeve and this 305603) are class 1. The sleeve length does not change the class; the contrast does. If the T-shirt is the only visible garment, choose single-colour.
Frequently Asked Questions
Why is it class 1 while the 305604 is class 2?
Because the two-tone contrast reduces the surface area of fluorescent fabric, and the EN ISO 20471 class depends on that surface area and on that of the retroreflective tape.
Do long sleeves raise the class?
No. The sleeve does not affect the class calculation in the way the colour does: the two-tone short-sleeve 305506 is also class 1.
What is Bird-Eye fabric?
A technical polyester knit with a honeycomb structure, breathable and quick-drying.
Can I use it as my only visibility garment?
Only in environments with slow or controlled traffic. For construction sites with machinery, class 2 is advisable.
What colour combinations are available?
Navy blue with fluorescent orange, navy blue with fluorescent yellow, green with fluorescent yellow and grey with fluorescent yellow.
