Youth mountain biking programs are growing faster than any other segment of the sport. Junior riders who feel like part of a team wear their shirts to school, rides, and family events. A custom youth MTB shirt costs under $24 and ships in a week. Here is what youth programs order, which sizes cover which ages, and how to set up a youth club shop that parents actually use.
Youth-specific sizing is available in the following styles:
Youth Airlume Cotton Athletic Tee (Bear Grips): the most popular youth shirt for MTB programs. Soft ring-spun cotton, youth proportions, available in sizes YXS through YXL. The same premium fabric as the adult version.
Youth Moisture-Wicking Performance Tee (Sport-Tek): the performance option for junior riders who wear their shirt on the trail. Moisture-wicking polyester that handles sweat during climbs and descents. The right choice for a youth MTB racing program or summer camp shirt.
Youth Performance Long Sleeve (Sport-Tek): for cooler mountain mornings and high-elevation trail riding. Sun protection on exposed alpine trails without adding bulk. The same performance fabric as the youth tee in a long sleeve cut.
Youth Hoodie (Gildan) and Youth Crewneck Sweatshirt (Gildan): for cold-weather rides, post-ride hangs, and end-of-season awards shirts. See the hoodie guide for how these pair with the youth tee in a club shop.
Youth mountain biking programs that issue matching shirts see stronger team cohesion, better parent engagement, and more consistent show-up rates at group rides. The shirt signals commitment and belonging.
Common youth MTB program apparel setups:
Youth sizing in this catalog:
| Age range | Recommended size | Notes |
|---|---|---|
| 5-7 years | YXS | Most youth MTB programs start at this age |
| 8-10 years | YS or YM | Active kids tend to size up for movement |
| 11-12 years | YL or YXL | Many fit in adult small at this age as well |
| 13-15 years | Adult XS or S | Most teens have outgrown youth sizing |
| 16+ years | Adult S through M | Full adult sizing applies |
Set up your shop with both youth and adult sizing options under the same design. Parents of younger kids choose youth sizes; teen riders choose adult sizing themselves. One shop link covers the full program age range.
Beyond shirts, the catalog includes youth athletic shorts and outerwear:
Youth Athletic Mesh Shorts (Sport-Tek): 7-inch inseam mesh shorts in youth sizing. Good for casual summer riding and warm-weather trail events. These are non-padded athletic shorts for casual use and club branding, not technical cycling shorts with a chamois.
Youth Crewneck Sweatshirt and Hoodie: for post-ride warm-up, cold mornings at the trailhead, and end-of-season awards nights. A hoodie with the club name becomes a year-round wearable for most junior riders.
Youth MTB apparel programs that offer a shirt-plus-shorts or shirt-plus-hoodie bundle see higher average order values from parents. Parents buying a "full kit" in one checkout often spend 50-70% more than those ordering a shirt alone.
Custom youth and adult mountain biking shirts. No minimums, free shipping, US printed. Kids love wearing their club shirt.
Start FreeYouth XS through Youth XL in most styles, plus adult XS through 3XL for teen riders. Set up both size ranges in your shop so all ages can find the right fit.
