Thanks to improvements in both materials and design, contemporary mountain bike pants are almost unrecognisable from the original motocross garments of yesteryear – offering improved comfort and even waterproofing. Mountain bike trousers as they are known in the UK, or pants to those of you in the US have come a long way since motocross-style gear was adopted for mountain biking. The best mountain bike trousers will ensure there is plenty of adjustments to tailor the fit perfectly around your waist and the ankle cuff and some even feature over-shoulder straps or bibs that help to secure them in place and prevent your trousers from slipping down when the material becomes wet and heavy.
