Was dubious about buying, a bag, of the beeswift mp1 gloves, as I was actually looking for an alternate brand, I've had gloves before that were all bundled together, where the rubber was too hard and the material like an old rope, the company sent them out really fast delivery, individually wrapped, premium gloves, really happy, top drawer, as these will be stored in the garage, no damp or spider issues, big thanks to George @ gloves & stuff.

Decent gloves at a reasonable price. Delivered within a good delivery window. These gloves have reasonable longevity in medium workloads.

Good company to buy from; just took a bit longer than expected (9 days)from order to being despatched for delivery. The response was quick when I emailed them with a query. Will definitely use again.

C Cherie Rowdenvia Trustpilot

I've always had a good experience with this family run business, always able to ring and get any queries sorted. Quick delivery and products all as described on the website.
The process from order to delivery is smooth and stress free. I would definitely recommend them.

C Claire Davisvia Trustpilot

What an amazing company. I bought safety shoes from them and could not fault them with anything. Communication from the seller was spot on. Kept me updated on delivery times and delivery was super quick as well, not to mention that they had the best price out there. These shoes are so comfy :). Thank you very much, I would happily use them again and highly recommend to anyone. I am glad I did not cancel my order because of the previous bad reviews.

A pleasure to do business with George, Paul and the team. Have been using them for years and will continue to do so. Great customer service, speedy shipping and an extensive range of products.

Ordered some safety trainers as they offered the fastest delivery and lowest price. My order was a day late but this was due to a supply chain issue with the manufacturers. George kept me up to date and they still arrived before other company’s expected delivery date. The quality of the trainers are amazing and I will be definitely using this company again for my future supply’s.

Description

Six-in-One Protection That Converts When You Need It

The Portwest MV71 Modaflame Rain+ trousers handle arc flash, flame, chemical splash, and rain exposure whilst keeping you visible in hazardous environments. The genius zip-off bib design means you can convert these into standard trousers in seconds—one garment that adapts to different work scenarios throughout your shift.

Key Features:
  • Zip-Off Bib Design: Remove the bib completely when you don't need it. No more changing between garments—just unzip and you've got standard trousers. Perfect for workers moving between different risk zones.
  • Multi-Hazard Protection: Meets EN ISO 11611 Class 2 for welding, IEC 61482-2 Class 2 for arc flash, EN 13034 Type 6 for chemical splash, and EN ISO 11612 for heat and flame. This is CE-CAT III certified—the highest category for irreversible or fatal risks.
  • Advanced Modaflame Construction: Three-layer system with a 98% polyester and 2% carbon fibre outer shell, PU breathable flame-resistant coating, bonded to a 60% modacrylic and 40% cotton backing (350g total), plus a 100% cotton FR lining. Waterproof, breathable, and inherently flame resistant.
  • Class 2 High Visibility: FR reflective tape keeps you visible in low light. The Orange/Navy colourway meets railway-specific requirements per RIS-3279-TOM Issue 1. Contrast navy knee panels and hems hide dirt whilst maintaining a professional appearance.
  • Built for Comfort and Function: Pre-bent knees for freedom of movement. Internal kneepad pockets keep your profile clean and comfortable. Adjustable hems accommodate different leg lengths. Adjustable straps with durable buckle closures ensure a secure fit.
  • Practical Storage: Four pockets give you room for tools and essentials. All buttons and zippers are flame-resistant to maintain garment integrity—no weak points in your protection.
  • Anti-Static Properties: Meets EN 1149-5 for electrostatic discharge protection. Critical for electrical utilities, oil and gas operations, and anywhere static could spark a hazard.

Designed for electrical workers, welders, railway maintenance crews, and oil and gas professionals who need serious protection without compromising on flexibility. Portwest engineered these trousers for high-risk environments where one garment needs to do it all. Order yours from Glovesnstuff today.
