Tomboi Harness

$ 89.99

For a deluxe strap-on experience with ultimate comfort, try the original Tomboi. This brief-style harness features an impressively stable front panel with two internal vibe pockets for added stimulation (vibes sold separately). Inside the harness, two panels of soft fabric separate the dildo base from your skin if that's your preference. The fabric can also be easily drawn aside, making this harness totally compatible with double dildos. The durable, sewn-in O-ring is compatible with toys 1.25–2.25 inches in diameter, and the quick dry, nylon spandex fabric wicks moisture away from the skin when things get hot.

The Tomboi is comfortable enough for everyday wear, and also features an elastic packing strap on the inner panel so it can double as a pair of packing shorts. Is there anything this harness can't do? Well actually... it's not adjustable. So make sure you take careful measurements and check out our sizing information for an optimum fit!

Suggestions from the manufacturer:

Choose your harness size based on both your actual body measurements and body shape, not based on your typical pant or jean size, which varies significantly between brands, designs, and cuts. Please don't skip this step: the right size harness will give you the most comfort and support, and will always look better than a size that's just "almost right."


1. Get your lower waist/hip measurement. Wrap a measuring tape around your waist, about 1 inch (2.5 cm) below your pelvic bone. Mark the number where the tape measure completes and crosses over itself.

2. Use that measurement, as well as your body shape, to determine your size. Tomboi™ performs best when your body fills out the harness, so choosing the right size is crucial. You should take your body shape into account before selecting a size. To do so, think of your body in terms of moon phases: 


FULL MOON bodies have fuller curves. If you were to view this body shape from the side, you would see a half-moon shape in rear, and a quarter to half-moon shape in front, where the stomach is. If you have a full moon shape…choose the next size up.

THREE-QUARTER MOON bodies have a balance of curves and planes. If you were to view this body shape from the side, you would see a quarter-moon shape in front and a half-moon shape in rear, or a a flatter front stomach area and a fuller three quarter-moon in rear. This body shape typically has a fuller butt and, sometimes, wider hips. If you have a three-quarter moon shape…choose the next size up.

HALF-MOON bodies are curvier in rear, flatter in front. If you were to view this body shape from the side, you would see a half-moon shape in rear. If you have a half-moon shape…stay to the size chart.

QUARTER/CRESCENT MOON bodies have gentler, less pronounced curves in rear. If you were to view this body shape from the side, you would see a quarter (or crescent) shape sloping from the tailbone to the top of the thigh. If you have a quarter/crescent moon shape…choose the next size down. If you have a quarter/crescent moon shape in rear, BUT a quarter to full-moon curve in front, at the stomach. In that case, stay to the size chart.
