What the AI looks for in Girls' Cycling Underwear

Chamois scaled to youth sizing: Pad sized for the youth size, not a cut-down adult pad. A thin to medium foam pad suits a child's lower weight and shorter rides. An oversized or thick pad bunches and causes chafing on small riders, which defeats the purpose.
Worn without regular underwear: Designed to be worn directly against skin, with no cotton underwear underneath. Underwear under a chamois adds seams and traps moisture, which is the main cause of saddle soreness.
Flat seams around the pad: Flatlock or bonded seams. No raised stitching where the leg meets the saddle. Raised seams rub exactly where kids complain of soreness.
Waist and leg retention: Wide soft waistband or bib-style straps, plus light leg grippers that keep the liner from riding up. Kids change size quickly and liners that slip down or ride up get abandoned.
Fit with the outer short: If buying separately from baggy shorts, check that the liner's leg length sits shorter than the outer short. Liners that show below or bunch inside the outer short are uncomfortable and look wrong to kids.

Fox Racing: Makes youth mountain bike apparel; some youth shorts include or pair with liners.
Troy Lee Designs: Youth mountain bike line where liners are often bundled with shorts.
Pearl Izumi: Long-standing cycling apparel brand with padded kids' options.

Adult women's liners in the smallest size used for a child; pad placement and size will be wrong
Cotton underwear worn under padded shorts
Liners with thick gel pads for short neighbourhood rides
Liners with tight elastic leg bands that dig in

For pre-teens, unisex youth pads are generally fine. Fit and pad size matter more than gendered shaping until riders approach adult sizing.

No. The liner replaces underwear, and it should be washed after every ride.
