Trousers
Used MTB trousers split into two categories: technical riding trousers designed for the bike, and casual trousers from MTB brands for everyday wear. Riding trousers from Fox, Endura and Troy Lee use stretch fabrics, articulated knees and DWR coatings, while casual options from the same brands apply the same robust construction in more conventional cuts. For UK riding, full-length trousers with water resistance are the default from October to April.
What do technical riding trousers give you?
Technical riding trousers use four-way stretch fabric with a DWR (durable water repellent) coating. Fox Ranger and Defend trousers are the go-to trail options — articulated knees fit over pads, and tapered ankles stay clear of cranks. Endura MT500 trousers are the UK benchmark for waterproof riding, with proper seam sealing rather than just a spray coating. Troy Lee Designs Sprint trousers are popular for DH with a looser moto-influenced cut, and for cold, wet UK winters the lined waterproof trousers from Endura or 7mesh justify the premium.
Are casual MTB trousers worth buying?
Fox, Fasthouse and Dakine make casual trousers that use tougher fabrics than high-street chinos, typically with stretch panels, reinforced seat areas and discreet pockets for phones. They work for commuting to the trails and do not need changing at the car park, so they sit alongside sweatshirts and hoodies and tees and vests in the same off-bike wardrobe. Chromag produces workshop-style trousers in heavy canvas that cross over between riding and everyday wear.
Will they fit over knee pads?
If you ride with knee pads, trouser fit at the knee matters. Articulated or pre-shaped knees accommodate slim pads (POC VPD, Leatt Airflex), while baggy DH-cut trousers work with bulkier hard-shell pads. Straight-cut casual trousers usually do not work over pads — the bunching affects pedalling. Try your trouser and pad combination before committing, or buy trousers specifically marketed as pad-compatible.
What should I check buying used?
Check the DWR coating on riding trousers — pour water on the fabric and see if it beads; if it soaks straight in the DWR is gone, though re-proofing sprays like Nikwax TX.Direct can restore it. Examine the seat and inner thigh for wear from saddle abrasion, and check the knees for permanent stretching from pads. Zip and velcro closures at the ankles should still function cleanly. The rest of the MTB clothing listings are worth checking at the same time.
