Portwest Flexatex Chemical Resistant Trousers
When you're working in environments where chemical exposure is a genuine concern, you need workwear that delivers on protection without compromising on comfort. These chemical resistant rain pants have been engineered to handle demanding conditions whilst keeping you moving freely throughout your shift.
The outer fabric is crafted from 100% polyester with a breathable PU coating, giving you a balanced combination of waterproof performance and ventilation. Welded seams lock out moisture effectively, whilst the PFAS-free water repellent finish means water simply beads away from the surface rather than soaking through. An elasticated waistband works with the full stretch construction to ensure you can bend, crouch and move without restriction, and the adjustable hem with poppers lets you dial in the perfect fit around your boots.
These trousers meet stringent safety certifications including EN 13034 for chemical splash resistance and EN 343 Class 4:2 for weather protection. The combination of durability, breathability and windproof qualities makes them reliable for varied outdoor and industrial work.
Key Features
- Full stretch material with breathable, windproof construction
- Welded waterproof seams keep moisture out completely
- Adjustable hem with poppers for secure, customised fit
- Chemical resistant to 10% sodium hydroxide solutions
- PFAS-free water repellent finish for environmental responsibility
Recommendations from our Unishore Expert
If you're regularly exposed to chemical splashes or working in wet conditions, these trousers stand out as a premium choice. The breathable coating prevents that clammy feeling you sometimes get with purely waterproof gear, so you'll stay comfortable during longer shifts. The adjustable hem is genuinely useful if you're pairing them with different safety footwear, and the elasticated waist combined with full stretch means you won't feel restricted when you're working dynamically. The anti-fungal treatment adds extra value if you're working in damp environments. These are built to offer protection according to strict safety standards, giving you confidence that you're properly equipped.
