Factory Quick Specs
Product Description
Wholesale Kids 100% Cotton Sleepwear OEM (2-piece set) — model H638 — is a clean, gentle cotton pajama built for infants and school-age children who sleep, lounge and play in soft, breathable, naturally hypoallergenic cotton. The set is a long-sleeve pullover top paired with full-length pull-on pants — a classic two-piece silhouette that buyers across the wholesale market recognize for retail-ready inventory. The body is 100% pure cotton (no spandex blend) — the gentlest choice for sensitive young skin — and sized 90–140 cm across six size grades, with suggested heights from 80–90 cm (size 90) up to 130–140 cm (size 140).
Per the spec sheet’s fabric index, H638 carries three positioning indicators: slight stretch (sourced from the cotton fiber structure itself, NOT from spandex — the garment recovers shape gently but does not hug the body); medium thickness (substantial single-layer drape, more substantial than a thin rib-knit but lighter than a 280 gsm brushed thermal series); soft hand-feel (gentle against sensitive young skin and softens further with every wash). The 6-dimension flat-laid measurements cover chest, top length, sleeve length, pants length, waist (1/2 of full circumference) and suggested height — documented per size for transparent B2B ordering. H638 ships 2 pieces per retail-ready polybag so the set can route directly to your fulfillment center.
20 in-stock TZ prints are ready to ship, organized as 16 H638 prints (Gray Pegasus TZ709, Mermaid TZ706, Pink Castle TZ708, Yellow Construction Vehicle TZ702, Green Dinosaur TZ703, Blue-Heart-on-Blue TZ717, Yellow Floral TZ719, Deep-Blue Rainbow TZ720, Blue-Base Yellow Dinosaur TZ723, Gray-Base Green Dinosaur TZ727, White-Background Dinosaur TZ730, Astronaut TZ722, Pink Rainbow TZ718, Yellow-Background Dinosaur TZ721, Gray Rainbow TZ705, Royal-Blue Dinosaur TZ701) and 4 H804 cross-segment prints (White Shark Head TZ724, Train Head TZ725, Satellite Dinosaur TZ726, Orange Dinosaur TZ731). Custom artwork, including exclusive character IP, is welcome for OEM partners. H638 is positioned as the pure-cotton 2-piece sleepwear set alternative to our H923 2-piece pajama set (95% Cotton + 5% Spandex 5A main body, upgrade-positioned for older children) and pairs with our H961 girls pajama pants (100% Cotton, 1pc/bag) when buyers want single-piece add-on pieces.

Product Overview
For Kids

For Parents
Pure cotton is naturally hypoallergenic and easy to wash at home (30°C / 86°F). The set ships as a finished 2-piece outfit, so the top and pants always match; the cut runs slightly large per the supplier’s model-fitting note, so parents can size down for a closer fit.

From 2 pcs on selected in-stock styles, colors and sizes per style / print, custom TZ print development, woven labels, care tags and branded 2-piece polybag — a value-tier 100% Cotton sleepwear position for natural-fiber kids pajama lines across boutique, DTC and Amazon FBA programs.
Size Chart (6-Dimension Flat-Lay Measurements per Spec Sheet)
H638 is produced in sizes 90–140 cm, covering toddler to early primary children (suggested heights 80–140 cm per spec sheet). Sizes can be mixed within the MOQ.
Measurement Note (per spec sheet): Garment measurements are flat-laid in centimeters. Waist is 1/2 of the full circumference (multiply by 2 to get the full circumference). There is approximately a 1–2 cm tolerance range due to individual measurement habits — actual product measurements may vary slightly. Model-fitting note (per spec sheet): the cut runs slightly large; the fit feels moderate (not snug). Girl model: 90 cm height, 12 kg weight, wears size 110. Boy model: 90 cm height, 14 kg weight, wears size 110. Recommended: size down one code for a closer fit, or stay on the spec size for the model-noted moderate fit.

Frequently Asked Questions
What is the fabric composition of H638 Wholesale?
H638 is made from 100% pure cotton — no spandex blend in the main body. Pure cotton is naturally hypoallergenic, breathable and soft against sensitive young skin. The slight stretch cited in the spec sheet’s fabric index is sourced from the cotton fiber structure itself, NOT from synthetic elastic. This makes H638 a strong fit for brands seeking natural-fiber alternatives to spandex-blended kids’ sleepwear.
What sizes and ages does H638 Wholesale cover?
H638 covers sizes 90–140 cm across six size grades (90, 100, 110, 120, 130, 140), with suggested height ranges from 80–90 cm (size 90) up to 130–140 cm (size 140) — approximately 18 months to 8 years old. The detailed size chart includes 6 measurement dimensions per size: Chest, Top Length, Sleeve Length, Pants Length, Waist (1/2 circumference) and Suggested Height, with a 1-2 cm tolerance range per the spec sheet.
What does the fabric index on the spec sheet mean (slight stretch / medium thickness / soft hand-feel)?
The fabric index is a supplier-side positioning indicator — not a technical number. Stretch: slight — sourced from the cotton fiber structure, NOT from spandex; the garment recovers shape gently but does not hug the body. Thickness: medium — substantial single-layer drape, more substantial than a thin rib-knit but lighter than a 280 gsm brushed thermal series. Softness: soft hand-feel — gentle against young skin and softens further with every wash. The index guides styling, not specification.
How does the model-fitting note help me size H638?
Per the spec sheet’s model-fitting section: the cut runs slightly large and the fit feels moderate (not snug). The girl model (90 cm height, 12 kg weight) and boy model (90 cm height, 14 kg weight) both wore size 110 with a moderate fit. Sizing recommendation: choose the size whose Suggested Height range matches the child’s current measurement as the starting point, then size down one code for a closer fit per the supplier note, or size up one code if the child is at the upper end of the height range or you prefer a more generous fit.
What TZ print combos are available?
20 in-stock TZ prints: 16 H638 prints (Gray Pegasus TZ709, Mermaid TZ706, Pink Castle TZ708, Yellow Construction Vehicle TZ702, Green Dinosaur TZ703, Blue-Heart-on-Blue TZ717, Yellow Floral TZ719, Deep-Blue Rainbow TZ720, Blue-Base Yellow Dinosaur TZ723, Gray-Base Green Dinosaur TZ727, White-Background Dinosaur TZ730, Astronaut TZ722, Pink Rainbow TZ718, Yellow-Background Dinosaur TZ721, Gray Rainbow TZ705, Royal-Blue Dinosaur TZ701) and 4 H804 cross-segment prints (White Shark Head TZ724, Train Head TZ725, Satellite Dinosaur TZ726, Orange Dinosaur TZ731). Boys’ themes cover dinosaurs, construction vehicles, trains, sharks, astronaut and satellite; girls’ themes cover mermaid, castle, rainbow, floral, heart and pegasus; color-stripe themes (TZ705, TZ720) are unisex. Custom artwork is also welcome for OEM print development.
What is the MOQ, lead time and sample policy for H638?
Ready stock: MOQ Typically from 1,000 sets per design for standard custom programs, ready-to-ship within 48 hours from confirmed payment. Custom OEM MOQ: Typically from 1,000 sets per design for standard custom programs. Samples: sample yardage (a finished stock set + spec sheet) is available at nominal cost, refunded against the bulk order; full custom prototype samples (printed with your artwork) 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. The H638 fabric is a flat white-base pure cotton that accepts custom prints (placed or all-over), woven labels at the neck, hangtags on the set polybag, custom polybag sizing, gift-box packaging, and custom dyeing for brand-matched color stories. We also accept client-supplied artwork. 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 H638?
For every H638 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. We can also coordinate with your nominated testing partner (BV, SGS Asia, TÜV etc.) for an independent pre-shipment check.
Is OEKO-TEX Standard 100 available for H638?
OEKO-TEX Standard 100 application is currently in progress (not yet issued). In the interim, H638 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.
How should customers wash and care for H638 100% cotton sleepwear?
Per spec sheet: machine wash cold at 30°C / 86°F or below; tumble dry low; do not bleach; iron low if needed. Pure cotton may have minor shrinkage after washing — size up if the child is between sizes, or size down per the supplier’s model-fitting note for a closer fit. Avoid high-temperature washing and high-heat tumble drying to preserve fabric softness and fit over time. These care notes can be applied as a standard heat-transfer care label on the inside neck for OEM partners.
