Product Description
This leakproof thong and bikini underwear is designed for women who refuse to sacrifice style for functionality during light flow days. The minimal silhouette and ultra-thin 3-layer gusset maintain the invisible, panty-line-free aesthetic of premium lingerie while providing discreet protection against spotting, discharge, and light flow.
The 3-layer construction is intentionally thinner than the 4-layer system used in standard period underwear — the trade-off is lower absorbency (5-10ml) for a truly invisible profile under tight clothing, yoga pants, and athletic wear. This product is NOT designed to replace heavy-flow pads; it is optimized for light flow days, spotting, discharge, and as a backup for tampons or menstrual cups.
Two style options: thong (most minimal) and low-rise bikini (slightly more coverage). Two outer fabric options: Polyester/Elastane or Nylon/Spandex. Standard styles use durable flat-lock stitching; seamless bonding technology (no-stitch construction, "laser-cut" aesthetic) is available as an upgrade for completely invisible appearance.
Available in classic black and nude tones for invisibility under light-colored clothing. Custom Pantone dyeing available for OEM orders. For Amazon and Shopify sellers, unbranded product images and video assets are provided upon order placement to accelerate listing creation.
For private-label buyers, this style is available from 300 pcs per design with 72-hour sampling and full OEM/ODM customization.

Frequently Asked Questions
What is the fluid capacity?
Approximately 5–10ml — optimized for light flow, spotting, discharge, and backup use with tampons or cups. Not intended to replace a heavy-flow pad. The minimal fabric area of thong/bikini styles limits absorbency capacity.
Can the seams be made completely invisible?
Yes. Standard styles use durable flat-lock stitching. Seamless bonding technology is available as an upgrade — providing no-stitch construction and a "laser-cut" aesthetic for completely invisible appearance.
Are these suitable for sports or activewear brands?
Yes. The high-stretch outer fabric and minimal coverage make them invisible under yoga pants and athletic wear. An excellent cross-sell product for activewear brands.
Do you provide media assets for e-commerce sellers?
Yes. Upon order placement, unbranded product images and video assets are provided for Amazon and Shopify sellers to accelerate listing creation.
