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.

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.

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.

Portwest Merino Wool Thermal Protection Baselayer Top

Portwest Merino Wool Baselayer Top 1/4 Zip Thermal Protection

Regular price From £37.89 exc VAT £45.47 inc VAT

Description

Premium Merino Blend That Works as Hard as You Do

The Portwest B184 Merino 1/4 Zip Baselayer Top combines the natural performance of merino wool with hard-wearing polyester. Built for all-season comfort, this baselayer keeps you warm when it's cold and cool when you're working hard. The 50/50 merino-polyester blend delivers proper thermal protection without the bulk, making it ideal for layering under work clothing or wearing on its own during milder conditions.

Key Features:
  • Natural Moisture Management: Merino wool wicks sweat away from your skin, keeping you dry during physical work. No clammy feeling, even on demanding shifts.
  • Built-In Odour Control: The antimicrobial properties of merino wool mean this top stays fresher for longer. Fewer washes, better comfort between shifts.
  • Quarter-Zip Ventilation: Easy temperature control when you need it. Zip up for warmth, open it when you're working hard. Simple, effective adjustment.
  • Flat Lock Seams: No irritating rubbing or chafing during extended wear. The flat lock construction sits smooth against your skin all day long.
  • Lightweight 140g Fabric: Proper thermal protection without feeling bulky. The lightweight construction moves with you and doesn't restrict movement under other layers.
  • Durable Polyester Blend: The 50% polyester content adds durability and faster drying times compared to pure wool. Gets the best from both materials.

Part of Portwest's All Weather Protection range, this baselayer is designed to handle the rigours of everyday wear. Available in black from size S to XXXL, it comes in retail box packaging. Whether you're working outdoors in winter or need a reliable base layer for active work, the Portwest B184 delivers real performance where it counts.
