Description
KOSTO Aluskin pants are designed for workers exposed to molten metal splashes, flames and heat in aluminum smelting, foundry and welding environments. Their lightweight 330 gsm flame-resistant fabric combines viscose, polyamide, wool, aramid and antistatic fibre to provide protective performance with a comfortable fit. Reinforced stress points, Nomex®-resistant thread and a double-layer fly support durability and protection in demanding industrial conditions.
Key Features
Multi-hazard protection: Helps protect workers exposed to molten metal splashes, heat, flame, welding projections and electric arc hazards.
Comfort-focused fit: Lightweight fabric and a half-elastic back waist support comfort during wear.
Reinforced construction: Heavy Nomex resistant thread and reinforced seams strengthen high-stress areas.
Practical storage: Side slash pockets and a rear pocket provide accessible storage for work essentials.
Multiple inseam options: Available in 31", 33" and unfinished 36" inseams to accommodate different fit requirements.
Intended Use
Designed for metalworking environments where workers require protection from multiple thermal hazards.
Aluminum smelter work
Foundry work
Welding
Work involving molten metal exposure
Work involving Category 2 electric arc hazards
