Product Description
These seamless period swimwear bottoms combine a no-visible-panty-line aesthetic with 4-layer leak-proof protection — designed for swimming during menstruation without anxiety. The ultra-thin, seamless edges lay flat against the skin, feel like a second layer, and ensure no visible lines under swimwear or clothing.
The outer fabric is high-stretch, chlorine-resistant, UV-resistant, and quick-drying — the only Ljvogues swimwear model with both chlorine and UV resistance stated. This makes it suitable for repeated pool use and sun exposure without fabric degradation.
The 4-layer gusset uses a directional fluid management system: a fast-wicking inner layer pulls fluid away from the body, a high-density thin microfiber core traps menstrual fluid without absorbing pool water, and an extended TPU waterproof barrier prevents leakage with widened front-and-back wrapping. Leg elastics are optimized for aquatic use — snug fit prevents water flushing through the leg openings.
For private-label buyers, the product is available from 300 pcs per design with full OEM/ODM customization including custom prints (floral, tropical, solid colors), ribbed textures, heat-transfer logo, custom hygienic liners, wash labels, and eco-friendly packaging. Hydrostatic testing validates leak-proof performance on every batch.
Ultra-thin seamless edges lay flat against skin. No visible panty lines under swimwear or clothing. Feels like a second layer — discreet and comfortable.
Chlorine + UV Resistant
Outer fabric resists chlorine degradation (pool use) and UV damage (sun exposure). Only Ljvogues swimwear model with both resistances stated — suitable for repeated pool and outdoor use.
Leg Elastics Optimized for Aquatic Use
Pattern makers optimized leg elastic tension specifically for water use — snug fit prevents water flushing through leg openings, a common failure point in standard swimwear adapted for period use.
Extended TPU Wrapping
Waterproof barrier extends wider than standard at both front and back — providing coverage for the two most common leakage directions during swimming.
No Swelling in Water
High-density microfiber core is designed to absorb menstrual fluid while repelling pool water — preventing the swelling effect typical of regular sanitary pads.

Frequently Asked Questions
Will the absorbent gusset swell up when submerged in the pool?
No. The core uses specialized high-density microfibers protected by a TPU waterproof barrier. It absorbs menstrual fluid from inside while repelling pool water from outside, keeping the swimsuit discreet and flat.
Can these be worn as everyday period underwear?
While optimized for swimming with chlorine-resistant and quick-dry fabrics, the seamless 4-layer design is also comfortable for daily wear, sports, or workouts.
How accurate is the sizing?
Strictly graded with a tolerance of 1–2 cm. Swimwear requires a snug fit to prevent water flushing through leg openings — leg elastic tension is optimized for aquatic use.
