FAQs
What is the primary purpose of this base layer?
The primary purpose is to provide enhanced visibility, comfort, and body temperature regulation for professionals working in environments requiring high-visibility clothing.
Is this garment suitable for very cold weather?
As a base layer, it is designed for breathability and comfort. For very cold weather, additional insulating layers over this garment would be necessary.
How should I care for the reflective tape?
Follow the care instructions precisely: machine wash at 40°C, do not bleach, and tumble dry on low. Harsh chemicals or excessive heat can damage the tape's effectiveness.
Does the yellow color meet all safety standards?
The yellow color meets EN ISO 20471 standards. However, only the Orange variant complies with the specific RIS 3279-TOM standard for the UK rail industry.
What does UPF 40+ mean?
UPF 40+ means the fabric provides a Very High Protection rating, blocking at least 98% of the sun's harmful ultraviolet (UV) rays.
Can I detach the ID pocket?
Yes, the garment features a detachable ID pocket, allowing for flexible use depending on your needs.
How durable is the fabric?
The fabric is made from a highly durable nylon blend designed for workwear, featuring 4-way stretch for resilience and freedom of movement. Its certified performance lasts up to 50 washes.
Troubleshooting
Reduced visibility after washing
Ensure washing is done according to care label instructions (e.g., 40°C). Avoid harsh detergents or bleach which can degrade reflective tape and fabric over time. Certified performance is maintained up to 50 washes.
Fabric feels restrictive
Verify correct size has been selected using the size guide. The 'engineered active fit' and slim design are intended for close-fitting comfort and ease of movement; ensure no external layers are restricting movement.
Zippers are stiff or difficult to use
Gently try to move the zipper back and forth. If debris is present, clean it carefully. Lubrication with a wax-based product might help, but avoid oils that could stain the fabric.
Thumb loops feel uncomfortable
The thumb loops are designed for a secure fit. If they feel tight, ensure the sleeves are fully extended and try adjusting the garment's position on your arm. They are optional and can be omitted if preferred.
