CalExotics Boundless rechargeable multi-purpose harness

I recommend this rechargeable Boundless harness for anyone who wants strap-on penetration with integrated vibrations. The thick silicone probe combines a curved tip with 10 vibration, pulsing, and escalation functions, controlled with a single button. My customers often tell me they especially appreciate the memory chip, which automatically resumes the last function used. Another practical everyday detail: the travel safety lock prevents accidental activation once the harness is stored in a drawer or suitcase.

Ten functions and a curved tip

The probe offers 10 functions for vibration, pulsing, and escalation, accessible directly from the harness. Escalation mode gradually increases the intensity without requiring you to change functions yourself, making it useful for building sensation without interrupting the activity. Its curved tip provides more targeted stimulation during use. A memory chip stores the last function used, making it easy to return directly to your preferred setting from one session to the next.

Thick silicone and removable straps

The harness is made of thick silicone for greater comfort against the skin. The waist and thigh straps are elastic, fully adjustable, and removable, allowing you to adjust the position to suit your body type or try different configurations. A safety lock activates with a 3-second press, making it practical for transport or for preventing accidental activation.

Recharging and battery life

The harness recharges via USB, with cable included, and takes 2 hours and 30 minutes to fully charge. The stated battery life is 45 minutes at high speed and 90 minutes at low speed. Clean the silicone probe with lukewarm water and mild soap after each use, and use only water-based lubricant to preserve the material over time.

Who it's for and who it's not for

Ideal for: couples who want to combine strap-on penetration and vibrations without adding multiple separate accessories. It's also suited to anyone who likes being able to return to their favorite setting thanks to the function memory, without having to reprogram everything each time.

Less suitable for: anyone looking for a quiet, minimalist harness without electronics that need recharging. If you prefer a simpler version, check out our strap-on dildo selection to compare models without motorized functions.

A girlfriend's tip — Test the functions without inserting the toy before your first time together: this avoids surprises and helps you identify your preferred mode more quickly.
