Factory Quick Specs
Product Description
Wholesale Girls Seamless Underwear S2942 — Triangle Mid-Rise Cut — is a no-show, single-piece seamless underwear designed for girls aged 11–15. The main body is 68% nylon / 32% spandex, a classic seamless-knit blend that delivers strong four-way stretch and shape recovery with a smooth hand-feel against young skin. The inner lining layer is 92.6% rayon / 4.6% spandex + 28% polyester, providing soft moisture-wicking comfort against the body. The seamless knit construction removes side seams and elastic bands for an invisible fit under school uniforms, gym kit and loungewear.
The triangle mid-rise silhouette sits between classic brief and boy-short — full back coverage with a moderate leg-line that won’t show under slim pants or active wear. The seamless nylon / spandex body is breathable, quick-drying and shape-recovering, making S2942 ideal for active girls who need underwear that holds up through PE class, dance practice, sport and everyday wear. Sized S/M/L/XL in four size grades, the seamless knit stretches across the size range to accommodate growth.
S2942 is positioned as the seamless nylon-spandex companion to our girls cotton innerwear line (H755, H731, H886 etc.) and our developmental training bra (girls tween line). Custom color development on the nylon / spandex base, woven labels, heat-transfer logo and branded retail-ready polybag are also welcome for OEM partners. Every shipment ships in retail-ready polybags, ready to route directly to your fulfillment center for Amazon FBA, boutique or DTC retail channels.

Frequently Asked Questions
What is the fabric composition of this seamless underwear?
The main body is 68% nylon (polyamide) blended with 32% spandex — a classic seamless-knit blend that delivers strong four-way stretch, shape recovery and a smooth hand-feel. The inner lining is 92.6% rayon / 4.6% spandex + 28% polyester, providing soft moisture-wicking comfort against young skin. Rayon is the common B2B name for the regenerated cellulose fiber; it is soft, breathable and moisture-absorbent, making it well-suited for tween and teen skin.
What sizes and ages does S2942 cover?
Four size grades S/M/L/XL cover girls aged 11–15 (tween to mid-teen). The flat-laid measurements are S=27.5/13.5/19, M=29/14/20, L=30.5/14.5/21, XL=31.5/15/22 (waist / side length / hem circumference in cm, flat-laid). The seamless nylon / spandex knit stretches across the size range to accommodate growth and body-shape variation.
What is seamless construction and how does it help tween girls?
Seamless means the garment is knit as a single piece on circular knitting machines — no side seams, no elastic bands at the leg openings, no rigid closures. For tween girls whose bodies are still developing, this eliminates the scratchy seam points and tight elastic bands that traditional cut-and-sewn underwear can cause. The smooth seamless surface also stays invisible under school uniforms and slim activewear.
Is S2942 OEKO-TEX Standard 100 listed?
OEKO-TEX Standard 100 application is currently in progress (not yet issued). In the interim, S2942 is tested against GB 31701 Class A (China infant and children textile safety, the strictest tier covering formaldehyde, pH, odor and AZO amines), is documented for CPC (Children’s Product Certificate, US market — CPSC Lab 1693), and can be third-party inspected by TÜV SÜD / SGS / Intertek on a per-shipment basis. All dyes and materials meet eco-friendly standards during production.
What is the MOQ, lead time and sample policy?
Ready stock: MOQ Typically from 1,000 pcs per style and color for existing styles and existing print programs, ready-to-ship within 48 hours from confirmed payment. Custom OEM: MOQ quoted per colour or artwork — stock-fabric programs with from 2 pcs on selected in-stock styles, colors and sizes; fully custom dyed fabric: MOQ is confirmed after reviewing fabric composition, GSM, yarn count, size range, artwork, print method, construction and other customization requirements. Lead time ~25 days from artwork sign-off for new colours and ~45-55 days for fully custom dyed fabric. Samples: sample yardage (a finished stock piece + spec sheet) is available at nominal cost, refunded against the bulk order; full custom prototype samples take ~10-15 days and incur a small lab-dip fee.
Do you support OEM / private label and custom artwork?
Yes. We support OEM, ODM and private label. Custom color development on the nylon / spandex base, woven labels, heat-transfer logo, custom care tags and branded retail-ready polybag are all available. For exclusive character IP artwork, an NDA and a per-design fee may apply — share your target character / IP timeline and we will confirm feasibility.
What compliance documentation do you provide?
For every shipment we provide: commercial invoice and packing list; Certificate of Origin (Form A / E / F per destination); GB 31701 Class A test report per fabric batch; CPC documentation (Children’s Product Certificate) for the US market (third-party lab 1693); AZO-Free test report; care label compliance; and on request third-party inspection reports from TÜV SÜD, SGS or Intertek before shipment.
What does the spec sheet note about shrinkage and care?
The nylon / spandex body and rayon / spandex lining may have minor shrinkage after washing — size up for chunkier builds per the supplier’s note. Machine wash cold at 30°C / 86°F or below; we recommend washing inside out to preserve the seamless finish and color. Avoid high-temperature washing and high-heat tumble drying to preserve fabric softness and shape over time. These care notes can be applied as a standard heat-transfer care label on the inside back waistband for OEM partners.
How does S2942 compare to your cotton innerwear (H755, H731, H886)?
S2942 is a seamless nylon / spandex triangle mid-rise for tween girls (ages 11–15) who want a no-show invisible fit under school uniforms and active wear. H755 (100% cotton briefs), H731 (100% cotton ribbed boxer briefs) and H886 (95%+5% spandex 10A upgrade triangle briefs) are cotton-blend classic-cut briefs for younger girls (ages 2–13) who prefer natural-fiber comfort. S2942 fills the tween seamless nylon gap; H755/H731/H886 cover the younger cotton brief gap. The two product families complement each other across the developmental age range.
What does “triangle mid-rise” mean?
Triangle mid-rise sits between classic brief and boy-short — the cut provides full back coverage like a classic brief but with a moderate leg-line that does not extend down the thigh. The mid-rise waistband sits at the natural waist (between the navel and the hips). The result is a versatile silhouette that is more modest than a bikini and more visible than a boy-short, ideal for everyday school wear and active wear under slim pants and leggings.
