Who is this harness for?

The Tomboii Harness Briefs are great for:

• Folks who want a strap-on harness without the straps—brief style makes it super easy to wear and style discreetly.
• Anyone seeking gender-affirming expression through packing and pack-and-play scenarios.
• Users with dildo/vibrator collections that want a versatile harness compatible with multiple penetration options and angles.
• People with limited hand dexterity or joint flexibility who need an easy pull-on rather than complex buckle systems.

How to use the Tomboii?

1. Choose your dildo or vibrator—make sure it’s compatible with a 1.25" to 2.25" O-ring.
2. Insert the toy through one of the two O-ring slots (you can opt for angled play or double penetration compatibility).
3. Slide into the Tomboii brief harness like you would any pair of snug underwear—it's designed for a secure and body-conforming fit.
4. Position any bullets into the designated internal bullet pockets for added vibration (if desired).
5. Use the built-in packing strap across the shaft if you’re wearing the harness for pack-and-play or for secure positioning.

Great positions to try:

• Standing face-to-face: Ideal for mirror play or steamy make-outs that transition into penetration.
• Doggy style: Great for angle flexibility and strong thrust control with the internal support.
• Riding/cowboy/cowgirl: Your partner on top controls rhythm while you stay firmly in place underneath.

How to clean and care for the Tomboii?

• Cleaning: Machine-wash on cold in a garment bag or hand wash for long-lasting use. Hang or air dry (no tumble dry).
• Drying: Air dry flat or line dry to preserve fabric elasticity and prevent warping.
• Lubricant compatibility: Since this isn’t an insertable item, use a lube safe for the toy you’re pairing it with—water-based is usually a universal go-to.
• Storage: Fold and store in a drawer or breathable bag. Keep separate from silicone toys if also storing dildos inside pockets.

Harness practical use info:

• Versatility: Built for both penetrative and pack-and-play use.
• Support: Full-brief style ensures toys stay in place during a variety of movements and positions.
• Accessibility: No buckle or straps—just slide on like underwear. Can be especially useful for those with limited dexterity or who struggle with traditional harnesses.

Additional information:

• This might be suitable for folks who have trouble maintaining an erection, experience premature ejaculation, or erectile dysfunction because it can be a great way to penetrate and prolong sex.
• Also, this might be suitable for folks with limited mobility in arms/hands because it can provide a way to penetrate partner with a sex toy.

Special considerations when using Tomboii:

• Needs mobility and flexibility to put it on and use

User experience tips

• Wash before first use—New fabric garments can sometimes carry residue from manufacturing.
• Try wearing solo with a toy in a relaxed setting to get familiar with positioning before bringing in a partner.
• Layering with boxer briefs underneath can add extra support if needed, especially for dildo weight or prolonged use.
• For smoother removal post-play, use water-based lube sparingly—excess can get into fabric seams.
• Use a toy with a flared base or suction cup for better stability inside the ring slot.
• Store upright with your favorite dildo already in place so you’re always ready for action.
