PANTS
Kids' MTB Pants: Fox Youth Riding Trousers Explained
This category brings together kids' MTB pants – full-length riding trousers for young mountain bikers who ride trails, enduro laps and bike park runs. At Foxracing.si you will find youth pants from Fox, cut for children and teenagers rather than scaled-down adult sizing, and designed to take the abrasion of a crash while still allowing a full pedalling stroke. It is the right place to look if your child needs more leg coverage and protection than a pair of shorts can give.
What you will find in this category
- Trail and enduro pants – lighter, stretchy fabrics with a slimmer leg, made for pedalling to the top and riding all day.
- Downhill and bike park pants – tougher, more abrasion-resistant panels and reinforcement in high-wear areas such as the knees and seat, for lift-assisted and gravity riding.
- Race-oriented pants – close-fitting cuts with minimal bulk so they sit cleanly over knee pads or braces.
- Cooler-weather pants – for spring, autumn and muddy days, when bare legs get cold and dirty fast.
How to choose kids' MTB pants
- Size and growing room: youth pants are usually sized by age or a numbered youth size linked to waist measurement. Measure your child's waist and inside leg, and prefer a little length to spare over a pair that is already short.
- Knee pad compatibility: most young riders wear knee pads, so try the pants with the pads on. The knee area should be roomy enough that the pad does not pull the fabric tight when the leg is bent.
- Waist adjustment: ratchet closures, velcro tabs or internal adjusters keep pants in place on slim hips and allow some adjustment as your child grows.
- Fabric and stretch: look for a durable main fabric with stretch panels at the knee, seat and crotch – this is what lets a rider pedal seated without the pants binding.
- Ventilation: perforated or mesh panels and lighter fabrics matter in summer; solid, heavier fabrics are better for cold, wet and rough terrain.
- Discipline: pedal-focused riding rewards low weight and breathability, while downhill and bike park use rewards toughness and coverage.
- Fit at the ankle: a narrow, clean cuff keeps fabric away from the chain and cranks.
- Care: follow the garment label, wash off mud promptly and avoid fabric softener, which can affect water repellency and stretch.

Frequently asked questions
What size MTB pants should I buy for my child?
Use your child's waist measurement and inside leg length against the size chart for the specific model, and check the fit with knee pads on. If the measurements fall between two sizes, the larger one usually works better because it leaves room for pads and growth.
Are pants better than shorts for kids' mountain biking?
Pants give more skin coverage against scrapes, brush and cold, which is why they are popular for bike park and cooler conditions. Shorts breathe better in hot weather, so many riders own both and choose by season and terrain.
Do kids still need knee pads with MTB pants?
Yes. Riding pants protect against abrasion but are not impact protection, so knee pads should always be worn underneath.
Can kids' MTB pants be worn with a chamois liner?
Many riding pants have no built-in padding and are designed to be worn over a separate liner short with a chamois, which handles comfort on longer rides.
Are these pants suitable for downhill and bike park riding?
Look for models with heavier, abrasion-resistant fabric and reinforced knee and seat panels, as these are the ones intended for gravity riding, while the lightest pants suit trail and pedalling use.
