Thong Gaff - Black

Need a compression gaff that disappears under everything? Our bestselling black Thong Gaff is designed to create a smooth, secure silhouette without visible panty lines, making it one of our most-loved pieces of tucking underwear for everyday wear.

Whether you're wearing leggings, dresses, workout clothes, or your favourite pair of jeans, this gender-affirming thong stays discreet while providing our highest level of comfortable compression. Wear it with or without a tuck, depending on what feels right for you.

Unlike most trans underwear, this made-to-order Origami Customs Thong Gaff includes FREE custom sizing. We're the only brand offering custom-fit gaffs at no extra cost, creating a garment that's more comfortable, more secure, and made to fit your body, not the other way around.

High Compression Without Sacrificing Comfort or Safety

The front panel is made with two layers of our signature Powermesh, giving you our highest level of compression while still allowing the flexibility and breathability you need for everyday life.

The back features a single layer of semi-sheer mesh, creating a lightweight, barely-there feel that's just as comfortable as it is flattering.
