SpareParts Tomboi Cover Brief Style Underwear Harness
The SpareParts Tomboi Cover Brief Style Underwear Harness redefines strap-on play with a minimalist, underwear-style design that doesn’t sacrifice functionality. Crafted from premium black nylon, this size S harness offers a secure hold for dildos or vibrators while maintaining a sleek, bulge-free silhouette under clothing. Whether for pegging, role-play, or solo use with a harness-compatible toy, the Tomboi Cover delivers comfort and confidence.
Product Overview
The SpareParts Tomboi Harness is engineered for those who want a low-profile, brief-style harness that disappears under clothes. Its soft nylon construction feels smooth against skin, and the integrated O-ring sits flush against the pelvis for natural positioning. Two adjustable side straps let you fine-tune the fit, while the sturdy snap closure keeps everything in place during active use.
Material & Design
The harness body is made from a high-quality nylon/spandex blend that is stretchy yet supportive. This black-on-black design eliminates visible hardware, giving you a discreet look. The interior offers a moisture-wicking liner to keep you dry during extended wear.
Fit & Sizing Guide
Size S is designed to fit a broad range of waist and hip measurements thanks to its adjustable straps. The brief style sits low on the hips and provides full coverage in the back. If you are between sizes, we recommend sizing down for a snug, stay-put feel.
Compatibility
The Tomboi Harness features a flexible O-ring that stretches to accommodate dildos, vibrators, and packing toys with a base diameter up to 2 inches. It works with most standard flared-base dildos. Simply slide the toy through the ring from the inside, and the ring holds it firmly.
Care Instructions
This harness is machine-washable, making cleanup effortless. Wash in cold water with mild detergent and line dry. Avoid bleach and fabric softeners to preserve the nylon’s elasticity and moisture-wicking properties. The O-ring can be wiped down with warm soapy water or a toy cleaner.
