Tranemo Flame Retardant Base Layer Trousers 631190 | Two Fabric Weights Available
The Tranemo Flame Retardant Base Layer Trousers 631190 are available in two certified Merino wool fabric weights, giving a choice between the standard Merino RX and the higher-rated Merino JX with jacquard patterned panels. Both are knitted from inherent flame retardant wool and FR viscose, built for genuine cold-weather protection under outer trousers. The elasticated waist keeps the fit simple, and the PFAS-free construction keeps the fabric free from persistent chemicals.

- Two fabric options: 901 Merino RX (60% wool, 38% viscose, 2% antistatic, 200 g/m²) and 904 Merino JX (55% wool, 43% viscose, 2% antistatic, 220 g/m², jacquard patterned panels)

- Cold-weather shifts where insulation and flame retardancy both matter
- Layering within the Tranemo Skinsafe protective system
