What are hollow strap-ons?

A hollow strap-on is a dildo with a hollow core that fits over a penis, held in place by a harness around the hips or an elastic jock strap. Unlike a hollow dildo sold on its own, these come with the harness included. They add length and girth, stay firm regardless of what is happening underneath, and let the wearer feel the movement through the sleeve. Fetish Fantasy Series makes the widest range, Fantasy X-Tensions uses dual-density silicone, and Master Series, Addiction, Size Matters and Body Extensions make firmer silicone models.

Types of hollow strap-ons

Plain hollow strap-ons

The simplest option: a hollow shaft, often with balls, on a stretchy or adjustable harness. Fetish Fantasy Series makes several sizes including a ten-inch version and a limited edition, the Selopa Our First and the Me You Us Extender are inexpensive first buys, and Dr. Skin and Addiction add a realistic finish.

Vibrating and remote-controlled hollow strap-ons

A motor in the base or shaft lets both partners feel vibration. Fetish Fantasy Series offers vibrating and rechargeable models with wireless remotes, Lux Fetish has unisex versions with a wired remote, and the ZOLO penis extender and Fantasy X-Tensions Elite vibrating strap-on are rechargeable silicone options.

Silicone and dual-density hollow strap-ons

Fantasy X-Tensions Elite dual-density sleeves have a firm core under a soft outer layer so they feel closer to skin. Master Series makes slim, curved and thick hollow silicone strap-ons, and the Body Extensions Be Strong, Be Bold and Be Daring sets pair a silicone harness with a hollow dildo.

Double and fantasy hollow strap-ons

Body Extensions Be Ready and Be Naughty come with two hollow dildos, the King Cock Two Dildos One Hole suspender system and the Lux Fetish hollow double penetration strap-on carry two shafts, and the Creature Cocks King Kraken and Snow Wolf bring fantasy shapes to the wearer. The Master Series Pumper inflates for adjustable girth, and the Fetish Fantasy squirting model releases fluid on cue.

Extensions and sleeves

The Doc Johnson Strappy penis extension, the Extensions hollow sleeve with jock strap and the Fetish Fantasy Mr. Big sleeve are lighter, lower-profile options that add length without a full harness.

How to choose a hollow strap-on

Start with how it will fit the wearer, then think about what the receiver wants.

• Inner fit: the sleeve should slip on comfortably without pinching; check the inner measurements in the product details.
• Outer size: compare the insertable length and girth with what the receiver already enjoys, and go up gradually.
• Harness: stretchy elastic is quick and forgiving; adjustable buckles hold a heavier or longer shaft more securely.
• Material: silicone and dual-density models are firmer and easier to clean; softer blends feel more lifelike but are porous.
• Power: vibration adds sensation for both partners but means charging and keeping the motor dry.

How to use and care for a hollow strap-on

Put a little water-based lubricant inside the sleeve before putting it on, fit the harness snugly while standing, then lubricate the outside generously. Go slowly, check in with your partner about depth, and stop if anything hurts.

• Wash inside and out before and after every use with warm water and a toy cleaner, and dry the inside fully before storing.
• Remove bullets or keep charging ports dry on vibrating models.
• Hand wash fabric and elastic harnesses and let them air dry.
• Do not wear a tight sleeve or strap for long sessions without a break, and loosen it if anything feels numb or cold.
