Recommendations from our Unishore Expert

These long underpants are engineered for professionals who refuse to compromise on safety or comfort. The substantial weight and premium fibre composition create an effective thermal barrier, perfect for wearing beneath your outer workwear in demanding environments. The inherent flame retardant properties mean you're protected from the moment you put them on, with no special treatments to wear away over time. We'd recommend pairing these with the matching Blaklader flame retardant wool vest 4793 for a complete layering system that works cohesively. The elastic construction at the waist and ankles prevents bunching under tight-fitting work trousers, so you'll maintain that professional appearance throughout your shift.
