How we chose

Our team works with clients every day to test and wear this kit on real sites, and we listen to their feedback alongside what people say online and on review sites. We bring it all together so you get clear, honest information to pick the right product for you.

Using our supplier certification data, we screened the certified picks against EN ISO 11612 heat and flame codes (A1/A2 limited flame spread, B convective, C radiant, E molten iron, F contact heat), EN ISO 11611 welding protection (Class 1, A1/A2) and IEC 61482-2 arc protection (box-test class APC 1 and, where given, open-arc ATPV or ELIM in cal/cm²). We also read EN 1149-5 antistatic fabric, EN 13034 Type PB[6] light chemical splash protection and, on hi-vis picks, EN ISO 20471 Class 3 and RIS-3279-TOM Issue 2.

Every pick is active and in stock, with clear photos and sizes available. Scores weight review quality (38%, a Bayesian average rating), review volume (17%), our product research (30%: trade bestseller signals, price against the market, colour range and verified standards), photo coverage (8%) and size availability (7%). We only show verified ratings and review counts, with links, we pick no more than two products per brand, and every review summary is written in our own words.
