You’d hope that the more you pay, the fancier fabric and better performance you’d get, but knowing what to wear mountain biking isn't always that simple.
As a general rule though, sub-$50 / £50 will get you a packable emergency shell and sub-$100 / £100 will get you bearable weatherproof performance if you’re not killing yourself on climbs.

Depending on the brand, decent breathability and well-designed features for hard riding kick in at three figures and the real cutting edge cloth and fancy cuts will take you over $200 / £200 and beyond. Of course, that’s also when crapping yourself in case you crash and tear a massive hole in your new coat might make you sweat more than any fabric can cope with, so remember durability is a big part of the value.
