{"product_id":"spareparts-tomboii-black-red-nylon","title":"SpareParts Tomboii Black\/Red Nylon","description":"\u003cp\u003eThe SpareParts Tomboii Harness Briefs are a seamless slip-on alternative to traditional strap harnesses, designed to deliver body-hugging support without a single buckle, strap, or adjustment in sight. Made from a soft 85% Lenzing Modal (Rayon) and 15% Spandex blend, the brief conforms to your curves and stays firmly in place through every movement. Three internal bullet pockets let you layer vibration directly into the experience, while two reinforced O-ring slots — each accommodating dildo diameters from 1.25\" to 2.25\" — open up options for angled play or double penetration. A built-in packing strap across the shaft keeps things stable for pack-and-play sessions, and a discreet condom pouch keeps protection within reach. Available in sizes XS through 3X, with SpareParts recommending sizing up if you fall between measurements.\u003c\/p\u003e\u003ch2\u003eTomboii Harness Briefs features:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlip-on brief style:\u003c\/strong\u003e No straps, buckles, or adjustments — slides on like underwear for quick, fuss-free wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 85% Lenzing Modal (Rayon), 15% Spandex — soft, breathable, and body-conforming.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 internal bullet pockets:\u003c\/strong\u003e Hold bullet vibrators (not included) for added stimulation during wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 reinforced O-ring openings:\u003c\/strong\u003e Compatible with dildos and vibrators from 1.25\" to 2.25\" in diameter; supports angled play or double penetration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in packing strap:\u003c\/strong\u003e Secures shaft for pack-and-play functionality and prolonged wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondom pouch:\u003c\/strong\u003e Integrated pocket keeps a condom on hand for safe, spontaneous use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInclusive sizing:\u003c\/strong\u003e Available in XS through 3X to fit low waist measurements from 26\" to 52\".\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications \/ Size \u0026amp; material\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 85% Lenzing Modal (Rayon), 15% Spandex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody-safe note:\u003c\/strong\u003e Modal is a soft, breathable, skin-friendly fabric widely considered body-safe for external wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-ring diameter:\u003c\/strong\u003e 1.25\" – 2.25\" (both slots, all sizes)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize XS:\u003c\/strong\u003e Low waist 26\" – 28\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize S:\u003c\/strong\u003e Low waist 29\" – 32\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize M:\u003c\/strong\u003e Low waist 33\" – 37\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize L:\u003c\/strong\u003e Low waist 38\" – 40\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize XL:\u003c\/strong\u003e Low waist 41\" – 44\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize 2X:\u003c\/strong\u003e Low waist 45\" – 48\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize 3X:\u003c\/strong\u003e Low waist 49\" – 52\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizing note:\u003c\/strong\u003e Order one size up if you are between sizes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\/Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e SpareParts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIntensity \u0026amp; Experience Level\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eLevel:\u003c\/strong\u003e Beginner — \u003cstrong\u003eSensation:\u003c\/strong\u003e Restrictive \/ Wearable Support\u003c\/p\u003e\u003cp\u003eThe Tomboii is one of the most forgiving harness styles available — if you can pull on a pair of briefs, you can wear this harness.
