The Theo harness is handcrafted in the US and designed by Spareparts Hardwear. Fashionable and fun, the Theo is a harness that embodies comfort and confidence. Made with soft and breathable fabrics, the materials draw moisture from the body which keeps it cool when things get hot! The lightweight materials ensure a comfortable wear. It features an adjustable thong strap and belt, so it be altered to fit the body securely. The Velcro belt has a second elastic pull feature that locks your toy into position.
The o’ring is simplistic and stretchable, toys can be easily slid in and out. It accommodates a variety of dildos, including double dildos measuring 1.10 to 2.25 inches in width. The durable and elasticated o’ring doesn’t lose its shape. There are two internal pockets located above and below the o’ring, these conveniently hold mini bullet vibrators. When used with bullet vibes, these fall behind the toy and not between partners. This way both partners can enjoy the tantalising trembles of the vibrations without feeling the bullet vibes themselves.
The Theo is hand or machine washable, but not suitable for drying in the tumble dryer and comes with a satin storage pouch. The Theo harness is available in black in sizes A and B, which covers sizes XS to 5X. For exact sizes, please refer to the sizing chart.
