What is a hollow strap-on? A hollow strap-on is a strap-on harness system featuring a dildo with an open internal channel. Unlike solid strap-ons, the hollow design allows the wearer to slide inside the shaft for a more physically connected experience — and enables users who have difficulty maintaining an erection to participate in penetrative partner play. The hollow interior also lets users customize internal fit using padding. Hollow strap-ons are widely used in pegging, adaptive intimacy, and strap-on exploration for couples of all genders.

Frequently Asked Questions
What is a hollow strap-on and how does it work?
A hollow strap-on is a strap-on dildo with an open internal channel that allows the wearer to physically insert themselves inside the shaft. This creates a more connected, immersive experience compared to a solid strap-on worn externally. Hollow strap-ons are commonly used by couples where one partner wants fuller physical involvement, by users navigating erectile difficulties, or by anyone who prefers the sensation of being inside the toy during play. The exterior of the toy functions the same as any strap-on dildo.
How is this different from a regular strap-on dildo?
A standard solid strap-on is a non-hollow shaft worn in a harness with no internal channel — the wearer sits behind the toy rather than inside it. A hollow strap-on like the Infiltrator adds an internal cavity so the wearer can slide inside, creating direct physical connection between the wearer and the toy during use. This design also supports adaptive use by partners dealing with size differences, or those who want a specific external shape while retaining internal space for the wearer.
How is shipping handled?
All orders from TheDildoHub ship in plain, unmarked outer packaging — no product names, logos, or adult content visible on the outside. Billing is equally discreet, with charges appearing under a neutral business name on your statement. Orders are processed promptly and tracking information is provided once dispatched. If you have any questions about your shipment, our support team is happy to help.
Is the harness adjustable, and what body sizes does it fit?
Yes — the included heavy-duty harness features both waist and crotch strap adjustment. The waist strap accommodates circumferences up to 55 in (139.7 cm), and the crotch strap extends up to 21 in (53.3 cm). This makes it suitable for a wide range of body types. Both straps use standard buckle adjustment, making it straightforward to dial in a secure, non-slip fit before and during play.
Can I swap the dildo for a different toy?
Yes — the Infiltrator uses a metal O-ring mounting system, one of the most common and versatile harness standards in the industry. You can swap in any O-ring compatible dildo to customize the external size, shape, or texture of your setup. When shopping for compatible toys, look for a flared base designed for harness use and confirm the O-ring diameter matches the base of your chosen dildo.
What lubricant should I use?
Water-based lubricant is strongly recommended for this toy. The TPE shaft material can degrade when exposed to silicone-based or oil-based lubricants, which may cause the surface to become sticky or structurally compromised over time. Apply lubricant generously to both the external shaft and inside the hollow channel before use, and reapply during extended sessions as needed. Not sure which lube to choose? We offer lubes for every occasions!
Is this suitable for beginners?
Due to its size — 10 in (25.4 cm) total length, 8.5 in (21.6 cm) insertable, and 2.5 in (6.35 cm) diameter — this model is best suited for intermediate to advanced users already comfortable with larger insertable toys. If you're new to strap-on play, we recommend starting with a smaller strap-on set and working up gradually. Plenty of lubrication and patient, gradual progression are important at any experience level.
