I’m not sure my riding can live up to the name of this jacket, although pedalling through the winter snows, rain and ankle-deep mud on my local trails certainly tested it’s fit and function.
The fabric is a toughened nylon Polyamide under the name of Altura ‘Shield’. The ‘strategically located venting zones’ aren’t immediately apparent, but looking at the jacket with the light behind it shows thick material on the chest, the arms and the lower back of the jacket, exactly the areas exposed to more wind, rain and muck. The fit is more sculpted than a regular walking jacket, and with longer, skinnier arms – which works well in an extended riding position – but helmet and pads will need to be worn over the jacket as a result. There are two vast reversed pockets on the ribs, and an internal phone pocket with a headphone port. Sleeve fasteners are Velcro and the zip pulls are easy to manage when wearing gloves.
The Mayhem did a great job of keeping the weather at bay, and I didn’t overheat in it once. It’s survived plenty of brushes with the undergrowth too. It’s also available online cheaper than the list price, so if you need a bike specific waterproof I think it’s excellent value.
► Verdict: Good value and generally well-designed weatherproof jacket.
► Best for: High energy mountain bikers.
