Rockarmy Spitfire silicone suction-base dildo

The first time, you’ll discover a dildo that combines two qualities: realistic design and the sensation of its dual density, which makes all the difference. The Spitfire strikes a balance between a soft, welcoming exterior and a solid core that holds firm. I consider this model one of the essential penetration dildos for anyone seeking a realistic sensation without electronics—just material, geometry, and pleasure.

Silicone material and dual density

The Spitfire is made from 100% body-safe liquid silicone, with a matte, silky finish. What Rock Army calls “liquid silicone” is a premium silicone with an especially smooth texture and remarkable adaptability to body heat. Dual density means the exterior is soft to the touch (hence that enveloping sensation), while the core remains firm to provide stable, decisive penetration. That’s what makes it so effective with a harness: it doesn’t bend, it simply gives just enough.

It is certified IPX7 waterproof—you can rinse it in the shower and run it under warm water without worry. To clean it, use mild soap and warm water, followed by a little disinfecting sex toy cleaner (such as Waterfeel) for maximum hygiene. No chemical odor, no porosity. I find that reassuring, especially for regular use.

Dimensions and size—21 cm for deep penetration

The Spitfire measures 21 cm in total length, with a diameter of 4.62 cm at the base. It’s a “large standard” size—not enormous, but clearly intended for those who enjoy a noticeable feeling of fullness. The suction-cup base is wide and ergonomic: you can attach it to any smooth surface (tiles, a bathtub wall, or a bed with a waterproof sheet) and use it hands-free, which genuinely changes the game for solo exploration. It comes off easily by gently pulling at the sides.

Its weight (423 g) is reasonable for its size—heavy enough to stay where you position it, but not too heavy to store or handle. With a harness, this density creates a genuine penetration sensation rather than something that moves in every direction.

Uses: vaginal, anal, harness, couples

• Solo vaginal penetration with the suction cup or hands-free
• Anal penetration (the wide base prevents complete insertion)
• Compatible with standard strap-on harnesses for pegging
• Submersible in the shower or bath (IPX7)
• Compatible with water-based lubricant (silicone is NOT compatible with silicone lubricant)

Between us, strap-on play is a world of its own—and the Spitfire shines because it doesn’t bend, has some weight to it, and its realistic shape creates a genuine penetration sensation. Solo with the suction cup, it’s also highly effective: attach it, position it, and explore at your own pace. No muscle fatigue, just pleasure.

Who it’s for and who it isn’t

Ideal for: Those who enjoy realism without vibration, are looking for firm and stable penetration, or want to try a harness or suction cup. It also suits couples who want to vary their sensations. Its “large standard” size means it’s not for complete beginners, but it’s accessible if you already have some experience.

Consider something else if: You’re a complete beginner (look for a slimmer dildo instead), or if vibration is an absolute must. To get started, I recommend checking out our beginner sex toy guide—it can help you choose the right first size. If you want vibration, our range of vibrating dildos offers more options.

Advice from a friend— Start with a water-based lubricant (never silicone on silicone), try it in your hand before using the suction cup so you can get a feel for how it positions, and take your time. A realistic dildo of this quality is meant to be savored, not forced.
