What to Compare Before Buying
- Size: This version is Large, so compare it with the fit you need over your usual clothing layers.
- Colour: Orange is part of the product identity here, and the RIS 3279 TOM Issue 2 marking applies to orange only.
- Front fastening: The zipped front changes how the vest closes and sits compared with an open-front style.
- Standard marking: Check that EN ISO 20471 Class 2 and RIS 3279 TOM Issue 2 are the right markings for your intended use.
- Tape pattern: The band and brace layout is part of the vest design and may matter if you are comparing against a different reflective pattern.
Care, Cleaning and Storage
The vest can be washed at a maximum of 40°C on a mild process. Do not bleach, tumble dry, iron or dry clean it. Drip line drying is specified, so drying method matters if you want to keep to the care guidance.
Before You Decide
Confirm the orange Large version matches the fit and visibility markings you need. Check the zipped front, reflective tape layout and care instructions against how you plan to wear and maintain it.
