FR Piqué Long-Sleeve Shirt

A lightweight flame-resistant piqué long-sleeve shirt for demanding industrial environments — inherent flame resistance, antistatic performance and the breathability of a three-dimensional knit.

230 g/m² Knitted Piqué 60% Modacrylic EN ISO 20471

COMFORT / 01

Breathable 3D Piqué

The knitted piqué builds a three-dimensional surface that circulates air far better than a dense flat weave, and moves moisture away from the skin. Protection that stays comfortable across a full shift.

  • Three-dimensional piqué construction for air circulation
  • Supports moisture management and thermal comfort
  • 38% cotton content for a soft, natural feel

ANTISTATIC / 02

Electrostatic Dissipation

2% carbon antistatic fibre is knitted into the structure to dissipate electrostatic charge — the reason the shirt can be considered as a base layer in ATEX and explosive-risk clothing systems.

  • 2% carbon antistatic fibres knitted into the fabric
  • Documented performance according to EN 1149-5
  • Suitable for flammable gas, vapour and flash-fire environments

PROTECTION / 03

Inherent Flame Resistance

60% modacrylic makes OLSQ-9 self-extinguishing by fibre, not by treatment — protection against flame, sparks and radiant heat that survives the laundry cycle.

  • EN ISO 11612 performance A1, A2, B1, C1, E1 and F2
  • Self-extinguishing modacrylic construction
  • Flame-retardant HT reflective tape

Why knitted piqué?

A flat woven FR fabric protects but holds heat against the body. The three-dimensional piqué knit lifts the fabric off the skin, opening air channels and moving moisture out — the same EN ISO 11612 performance, worn for longer without heat stress.
