About Onyx
New Premium Fabric
Onyx is our softest collection yet. It is designed as a true sensory delight.
The fabric is made from a soft micro-spandex, a silk like nylon blend. It is breathable and moisture wicking to keep you cool. Onyx provides the same support as our mesh. It is even more sensory friendly and fully opaque, making it very versatile. Wear Onyx as the 'fit, or under it. When styled with mesh pieces, Onyx changes how you can wear them and allows you to style them in new ways. One customer said, “This fabric is the best thing that has ever touched my skin.”
Quick Fit Guide
All handmade items are made with stretchy but supportive materials. If you are between sizes, size down—especially if you prefer a snug fit.

Crotch Fit Descriptions
All options are made with a cotton lined crotch, unless otherwise specified or requested.Narrow- made with vulvas in mind, ideal for anyone who doesn't need any extra room in the crotch.
Wide- the same general shape as "narrow" but made wider. Ideal for either more general coverage in the low belly and pubic area or to fit external genitalia that doesn't require a ton of extra fabric to cover.
Extra Wide- has more rounded sides in the crotch area while still built flat and works best for external genitalia, giving a secure fit without much compression.
Pouch- built out in a rounded shape and made with external genitalia (anatomical or a packer) in mind.
Tuck/Gaff- made like our wide option but with 3 layers of mesh for compression and more coverage extended towards the back side.
Pack- built like our pouch option but made with an extra layer to help hold whatever is used to fill out the crotch area.
