Product Description

Model IY001 is a trunk-style men's incontinence boxer brief designed for brands targeting users who prioritize a second-skin feel and discreet, all-day comfort. The 92% cotton / 8% elastane fabric composition creates a soft, breathable, and stretchy wearing experience that feels closer to premium everyday underwear than medical protection wear.

The 4-layer leakproof system is integrated into a widened and lengthened gusset that extends from the front crotch area to the back hip, providing reliable protection when sitting, walking, sleeping, or changing positions. The absorbent core captures fluid quickly and locks it inside the inner layers, reducing the risk of wetness reaching outer clothing.

Smooth seams reduce friction and improve comfort for extended wear — a construction detail relevant for users who wear incontinence products throughout the day. The skin-contact layer is designed to maintain a dry surface even at capacity, reducing the risk of skin irritation.

For private-label buyers, Model IY001 is available from 300 pcs per design with full OEM/ODM customization across fabric, absorbency level, sizing, branding, and packaging.

How IY001 differs from the extended-coverage model: IY001 is the trunk-style, second-skin option with smooth seams and 92% cotton/elastane fabric (S–3XL). The extended-coverage model with open fly offers +80% greater protective surface area and a functional fly (XS–4XL). Both serve the men's incontinence category but address different buyer priorities.

Key Specifications

Size Guide (Flat Product Measurements)

Flat product measurements, not body measurements. Manual measurement deviation of ±4 cm is normal. Custom graded sizing available via OEM specification.

Note: The original page did not label Measurement A and Measurement B. Please confirm with the factory which measurement corresponds to waist and which to length/hip, and update the column headers accordingly.

4-Layer Leakproof Construction

The gusset is both widened and lengthened compared to standard designs, extending from the front crotch area to the back hip for protection in multiple positions — sitting, walking, sleeping, and position changes.

Design and Comfort Features

Second-Skin Fit

The 92% cotton / 8% elastane composition creates a soft, breathable, and stretchy fabric that conforms to the body. The trunk-style cut is shorter and more fitted than full-length boxer briefs, reducing fabric bulk and supporting an active lifestyle.

Smooth Seams

Smooth-seam construction reduces friction against skin — relevant for users who wear incontinence products for extended periods. The construction helps the garment feel like normal daily underwear rather than medical protection wear.

Extended Protective Gusset

The leakproof zone extends from the front crotch to the back hip, providing coverage during sitting, walking, sleeping, and position changes. The widened design addresses side leakage in addition to front and back protection.

Discreet Appearance

The product is engineered to look and feel like regular underwear. The outer fabric maintains a normal-underwear appearance, and the integrated leakproof system is not visible from outside.

Extended Protection Layer

The IY001 protective gusset is both widened and lengthened, providing extended coverage from the front crotch area to the back hip area.

This extended structure offers more reliable protection when sitting, walking, sleeping, or changing positions. It is especially useful for male users who need full front protection and extra back coverage compared with ordinary underwear.

Quality, Testing, and Compliance

Compliance documentation and test reports are available on request. Contact the Ljvogues team to confirm which certifications and test reports are available for Model IY001 specifically.

Wash Care

Washable & Reusable Design

IY001 can be positioned as a washable and reusable alternative to disposable pads or adult diapers. The product combines the appearance of underwear with diaper-like absorbent support, as shown in the visual explanation: incontinence underwear = diapers + underwear.

This makes it suitable for retail brands targeting eco-conscious, cost-conscious, or dignity-focused users who prefer discreet protection. It also provides strong value for B2B buyers looking for repeat-purchase products in the adult care and functional underwear category.

Frequently Asked Questions

What is the difference between Model IY001 and the extended-coverage boxer brief?

Model IY001 is a trunk-style, second-skin fit with smooth seams, 92% cotton/elastane fabric, and S–3XL sizing. The extended-coverage model features +80% greater protective surface area, a functional open fly, and XS–4XL sizing. Both provide 200ml / 4-layer protection but address different buyer priorities: IY001 prioritizes comfort and discreet fit; the extended-coverage model prioritizes maximum protection area.

Is the 200ml capacity suitable for severe incontinence?

A 200ml capacity is classified as heavy protection — suitable for significant urge incontinence, post-surgery leakage, and heavy stress incontinence. Actual wear time varies depending on flow amount, body movement, and individual use habits. OEM buyers can request an upgraded absorbent core for increased capacity.

What fabric is used and how does it perform for extended wear?

Model IY001 uses 92% cotton and 8% elastane — a soft, breathable, and stretchy composition that conforms to the body for a second-skin feel. Smooth-seam construction reduces friction for extended-wear comfort. The fabric maintains performance through repeated machine washing.

What is the MOQ and sampling timeline?

MOQ is 300 pcs per design. Prototypes ship within 72 hours of brief approval.
