What it does
FAQs / Q&A
What makes this different from other harnesses?
The Theo Cover is designed to feel like actual underwear, not equipment. The nylon-spandex blend and sleek cover design make it wearable under clothes all day, while the three vibe pockets and interior security strap add functionality that most harnesses skip.
How do the vibe pockets work?
There are three strategically placed pockets that hold bullet vibes or small toys securely against your body. The interior security strap keeps everything positioned exactly where you want it during movement.
What sizes does the elastic O-ring accommodate?
The elastic O-ring is designed to stretch and accommodate various attachment sizes. It's more flexible than rigid ring systems, making it compatible with most standard-sized attachments.
Can I wear this discreetly under regular clothes?
Absolutely. The cover design and underwear-like fit make it genuinely wearable under clothing without any visible lines or bulk. It looks and feels like regular underwear from the outside.
Is it safe to share between partners?
The harness itself can be shared after proper cleaning, but any attachments should be cleaned thoroughly between partners or covered with condoms for safety.
How long will the elastic components last?
With proper care including air drying and storing with the O-ring cover in place, the elastic should maintain its integrity for years of regular use. The brass snaps are also built to last.
What's the fit like for different body types?
The nylon-spandex blend stretches to accommodate various body shapes comfortably. SpareParts is known for inclusive sizing that works well across different body types.
