Tranemo Flame Retardant Turtleneck Base Layer 631990 | Merino Wool & Arc Flash Rated
The Tranemo Flame Retardant Turtleneck Base Layer 631990 brings the same certified protection as the round-neck version, with a turtleneck collar and concealed zip for extra coverage in colder or more exposed conditions. Knitted from inherent flame retardant Merino wool and FR viscose, it moves with the body across long shifts. The extended back and PFAS-free construction round out a base layer built to be worn every day without irritation.
Key Features:
- Fabric: 60% wool, 38% viscose, 2% antistatic (Merino RX), approximately 200 g/m², inherently flame retardant
- EN ISO 11612 flame and heat protection, index A1+A2, B1, C1, F1

- EN 1149-5 anti-static certification
