Who is this harness for?

The Tomboi is ideal for:

• Beginners and experienced users who appreciate the ease of a pull-on harness with no straps, buckles, or adjustments.
• People with limited mobility in their hands/arms looking for secure control during strap-on play.
• Trans and nonbinary folks who want a comfortable, stealthy harness for packing, playing, or both.
• Partners interested in switching roles, exploring pegging, or experimenting with new positions and toys.

How to use the Tomboi?

1. Choose the right size based on your low waist measurement—this ensures a snug, comfortable fit without slipping.
2. Slide it on like a pair of briefs. There are no straps or buckles to adjust—it’s designed to hug your body like everyday underwear.
3. Insert your toy through the front O-ring. The internal fabric panels will secure the base and protect your skin from friction.
4. Use the mini-vibe pockets (if desired) for added stimulation using small vibes like bullet vibrators.

Great positions to try:

• Doggy style: The form-fitting shape allows maximum motion and control.
• Face-to-face sitting or standing: Easy to switch angles while maintaining connection.
• On top/cowgirl: Lets the wearer grind comfortably into their partner with total control.

How to clean and care for the Tomboi?

• Cleaning: Machine wash cold on gentle cycle or hand wash with mild detergent. Air dry or cool tumble dry.
• Drying: Avoid high heat to preserve the elasticity of the spandex blend.
• Lubricant compatibility: Since it's a fabric harness, make sure any lube stays on the toy—use a base condom to help avoid lube transfer to fabric.
• Storage: Store flat or folded in your underwear drawer or toy box. Keep away from sharp hooks, velcro, or zippers to prevent snags.

Harness practical use info:

• Versatility: Designed for both play and everyday wear—packable, playable, and breathable.
• Stimulation: Compatible with harness-ready toys, mini-vibes, and packers.
• Accessibility: Wide size range and step-in design make it ideal for various body types and abilities.

Additional information:

• Decreased sensation: Can help folks with erectile dysfunction or premature ejaculation enjoy hands-free, penetrative intimacy.
• Limited mobility: Offers control and support without buckles—especially helpful for those who may have hand or finger pain or flexibility limitations.

Special considerations when using Tomboi:

• Mobility requirements: Wearer must be able to step into and pull up brief-style harness.
• Dexterity: Minimal dexterity needed; great for those who prefer buckle-free gear.
• Reach: Basic reach to hips/genitals is required for toy setup and fit check.

User experience tips:

• Try it solo first: Wear the Tomboi while riding a toy on a pillow or dildo mount to get a feel for control and comfort before partnered play.
• Chill the base: If you're adding a vibe, make sure it’s secured and test battery life before play—bullets can add a whole new layer of pleasure.
• Use a dildo stabilizer ring if your toy feels slightly loose—the internal O-ring is stretchy, but added grip helps with firmer control.
• Pre-load the harness with your toy, so you’re ready to slide in when the mood strikes.
• Pair with a boxer brief for more gender-affirming coverage post-play if needed.
• Wash promptly after use to avoid any lingering lube or body fluid odors—machine washable convenience makes this easy.
