IY008 Women's 4-Layer Leakproof Period Panties | 100ml Ultra Absorbent Seamless-Comfort Menstrual Underwear | OEM/ODM Wholesale

Ultra-Light Period Protection

IY008 is designed for brands that want a lightweight, stretchy, second-skin period panty with strong leakproof performance. It combines everyday underwear comfort with a four-layer protective gusset, giving wearers a discreet alternative to bulky pads or disposable period products.

The style uses 92% cotton and 8% elastane, offering a soft hand feel with comfortable stretch for daily movement. Smooth seams help reduce friction and visible lines under clothing, making the product suitable for all-day wear during the menstrual cycle.

4-Layer Leakproof System

The IY008 gusset uses a four-layer widened and lengthened leakproof structure built for protection against front, back, and side leakage.

• Breathable Layer: Helps move moisture away from the skin for a drier feel.

• Large-Capacity Absorbent Layer: Holds menstrual fluid securely inside the gusset.

• Leakproof Antibacterial Layer: Helps prevent liquid from passing through to outer clothing.

• Main Fabric Layer: Keeps the panty looking and feeling like regular underwear.

100ml Ultra Absorbency

IY008 is marked as ULTRA absorbency with up to 100ml capacity, making it suitable for heavier protection needs than standard light-flow period underwear.

This absorbency level makes the product suitable for daytime heavy flow, overnight backup, postpartum spotting, bladder leaks, or as extra protection when paired with a tampon, cup, or pad. For B2C listings, it is recommended to describe it as up to 100ml absorbency, because actual wear time depends on flow volume and individual use habits.

Extended Protective Layer

The key selling point of IY008 is the extended protective layer. The four-layer gusset is widened and lengthened from the front crotch area to the back hip area, giving more protective coverage than ordinary underwear with a short gusset.

This design makes the product more reliable when sitting, sleeping, exercising, or changing positions. In product copy, it can be described clearly as: “Incontinence underwear = underwear + diaper-like protection” for bladder leak use, or “period underwear = underwear + built-in absorbent pad” for menstrual use.

Breathable Second-Skin Fabric

IY008 uses selected breathable fabric with a lightweight, stretchy hand feel. The product image highlights “Ultra-Light & Stretchy Second-Skin Feel,” which is suitable for marketing toward comfort-focused consumers.

The fabric is also shown with a water-vapor breathability display, supporting the idea of better airflow and reduced stuffiness during long wear. This is especially important for period underwear, where consumers often worry about heat, dampness, and irritation.

Smooth Seam Construction

The product detail photos highlight three construction points: four-layer leakproof gusset, smooth seams, and comfy inner lining.

Smooth seams help reduce rubbing around the leg openings and waistband area, while the comfortable inner side improves wearability during sensitive menstrual days. This makes IY008 suitable for both everyday retail and private-label premium collections.
