Product Description
The SpareParts Tomboii Nylon Boxer Style Strap-On Harness skips the buckles, skips the straps, and slides on like a pair of boxers. That's it. That's the whole setup. Pull them on, grab your dildo, get to work.
This is the strap-on harness for beginners and veterans alike who want something that actually fits their body and doesn't feel like an arts-and-crafts project mid-session. The Tomboii runs in 77% nylon, 23% spandex, so it moves with you, holds its shape, and stays comfortable through whatever you've got planned. Athletic cut, low-waist fit, and enough stretch to size up to 5X without losing structure.
Built for pack-and-play use, double penetration setups, or a straight-up good time with a partner. The internal packing strap and dual O-ring openings make this one of the most versatile boxer-style harnesses on the market. Add a bullet vibe in one of the three bullet pockets and you've got a whole situation going on. Available in Black/Red.
- 3 bullet pockets for added stimulation
- 2 O-ring openings for varied angles or double penetration
- Internal packing strap for pack-and-play
- Condom pouch included
- O-ring diameter: 1.25 to 2.25 inches (3.17 to 5.71 cm)
- O-ring circumference: 3.92 to 7.07 inches (9.97 to 18.0 cm)
- Fabric: 77% Nylon, 23% Spandex
- Sizes: XXS through 5X (waist 23 to 60 inches)
The Tomboii is ideal for LGBTQ+ couples, strap-on beginners, and anyone who prefers a gender-affirming harness fit without messing around with buckle systems. It's also a solid pick for packing throughout the day before play, since the cut is discreet under clothing and the waistband doesn't dig. Works best with dildos sized to the O-ring range listed above.
