LEATT MONO SUIT MTB HYDRADRI 5.0 £369.99

If you’re the kind of rider who absolutely has to go out, horizontal rain notwithstanding, the Mono Suit from Leatt could be your sartorial choice for 2023. After all, we’re either going to be deluged in rain or snow this winter, depending on which climate crisis expert you listen to.

The onesie concept is simple, and one Dirtlej pioneered a few years back. Take a waterproof jacket and trouser, stitch them together and you’ve got an extra skin that no trace of water can possibly enter. It’s more sophisticated than that, of course – the Mono Suit is made from Leatt’s own three-layer Hydradri MAX membrane, which boasts waterproof and breathability figures of 30,000mm/30,000g. On paper that means it can stand up to rain and sweat as well as Gore Tex’s Infinium membrane found on our favourite Rapha jacket, and Endura’s own Exoshell fabric. It also beats the Dirtlej onesie, with double the breathability rating.

No fabric can vent sweat enough on a warm ride when you’re working hard though, and so Leatt has chopped in ventilation zips galore, and there’s even a full-length Climbvent to open up the front. Leatt has also built in something called a Ride Adaptive Hood, which is a fancy way of saying a posh hood you can wear in four different ways, and there’s a magnet to hold it in place when you don’t have it up. Keeping everything in place is a myriad of Velcro fasteners and ties, and a set of braces to support the pants section and take the weight off the upper fabric. It also gets YKK Aquaguard zips, fully taped seams and a DWR coating. hotlines-uk.com
