Fristads Flamestat Devol Long Underpants 7437 109849

Looking for flame-retardant long underpants that actually keep you comfortable during long shifts? The Fristads Flamestat Devol long underpants deliver serious protection without compromising on wearability. Built with a thoughtful blend of merino wool, viscose and polyamide, these multinorm underpants work as an ideal base layer for high-risk environments. The inherently flame-retardant properties mean the protection is built into the fibres themselves, not just a surface coating. You'll stay warm and dry thanks to the moisture-wicking capabilities and quick-drying performance. The fabric is also PFAS-free, and at a lightweight 230 g/m², these underpants won't add bulk under your workwear. Full stretch construction ensures freedom of movement, whilst the front gusset design adds practical functionality. Whether you're working in electrical environments or around heat sources, these long Johns provide the reassurance you need.

Key Features

• Merino wool blend keeps you warm and dry

Recommendations from our Unishore Expert

If you work in roles involving electrical hazards or thermal risks, these long underpants are a smart investment. The merino wool content regulates body temperature effectively, making them suitable for variable working conditions. Layer them under your flame-resistant trousers for enhanced protection and added thermal insulation. The full stretch design means they move with you, not against you. What sets these apart is the combination of inherent flame protection with genuine comfort, so you're not choosing between safety and wearability.
