About Hollow Strap-Ons

A hollow strap-on is a dildo with an open core, worn over the penis or a packer and held in place with a harness. It adds length and girth while worn, for partner play.

  • Sizes: listed lengths run from 7 to 10.1 inches and widths from 1.5 to 3.2 inches.
  • Materials: mostly silicone, with TPE, plus an inflatable hollow model.
  • Prices: $64.95 to $213.95. Nine of ten are listed as harness compatible or include a harness.

How to choose: check the inner opening and the outer width on each product page, and pick an adjustable harness for a secure fit. Use water-based lube with silicone.

Every order ships in a plain box, and shipping is free over $85. Need a harness or a different style? Browse strap-on harnesses or penis sleeves.
