Connected Dual-Motor Sonic Wave Masturbator XL — F1S V3 XL

The XL version of the third-generation Lelo F1S — same SENSONIC technology as the standard size, but with an enlarged internal diameter for thicker penises or users who prefer more space inside the sleeve. Matte black casing with a clear window that reveals the red sleeve inside.

XL size for thick penises or those who dislike tightness

This is the only difference from the standard F1S: the internal channel is wider, and the silicone material has more room to stretch without compressing. If you've ever tried a masturbator that was too tight, or if you have an above-average girth, this version prevents you from feeling the material squeeze your penis. The stimulation remains applied but without constraint.

SENSONIC: sound waves that penetrate tissues

As with the standard model, a second motor sends low-frequency acoustic waves through the silicone. These waves pass through the material and propagate into the tissues — you feel the stimulation inside the glans and all around, not just on the surface. This is what distinguishes the entire F1S range from classic vibrating masturbators.

Ten sensors and Lelo app for real-time adjustment

The XL sleeve retains the ten SDK sensors that measure pressure, speed, and cadence. The Lelo app displays your movements live, and you can control both motors independently from your phone. Cruise Control mode maintains constant intensity even when you tighten your grip. Pre-recorded modes can also be customized and saved to your profile.

Removable medical-grade silicone sleeve and magnetic charging

The XL medical-grade silicone sleeve completely detaches from the casing for thorough cleaning with warm water. The non-porous material is durable and remains hygienic between sessions. Charging is via a magnetic connector, with a soft-touch matte finish that doesn't slip in your hand, and approximately two hours of battery life with mixed vibration + wave usage.
