When buying harnesses it's always worth looking for FIA/SFI approved products as this means they're of high quality and meets racing standards.
Why does it matter? It’s so customers know that when they're buying equipment that’s approved by FIA/SFI that it's of high quality. But more importantly that the equipment has been tested and proven to be safe; that it will actually work as advertised (i.e. that cheap Ebay fire-suit that isn’t actually “fireproof”).
This causes manufacturers to meet these standards, improve their equipment, and helps to raise safety overall - over the past 10 years we've noticed quite a few changes within the industry. We only sell genuine products, Rival Motorsport are dealers for most safety harness
brands in the UK.
