The Complete Strap-On Kit Checklist: What's Included and What You Need

Shopping for your first strap-on kit can feel like stepping into a whole new world of options. With so many harnesses, dildos, and accessories out there, it’s easy to get overwhelmed. But here’s the good news: a quality strap-on kit is designed to take the guesswork out of the equation. Whether you’re buying for yourself or as a gift, knowing what’s typically included—and what you might want to add—will help you make a confident, informed choice.

This complete strap-on kit checklist breaks down the standard contents, the optional extras that can level up your play, and the key factors to consider before you hit “add to cart.” By the end, you’ll know exactly what to look for in a strap-on kit, whether you’re a total beginner or a seasoned pro.

What’s Typically Included in a Strap-On Kit

A standard strap-on kit usually includes two core components: a harness and a dildo. The harness is the wearable part that secures around your hips or thighs, and the dildo is the insertable piece that attaches to it. Many kits also come with an O-ring or interchangeable rings to accommodate different toy sizes, which is a huge plus if you like variety.

Some beginner-friendly kits go a step further and include a bullet vibrator or a small pouch for storage. For example, the Carter Strap-On Kit | Signature Leather Harness comes with a leather harness and a silicone dildo, giving you everything you need to start right out of the box. If you’re just exploring, a kit like this is a solid, no-fuss entry point.

• Harness (adjustable for a secure fit)
• Dildo (silicone or other body-safe material)
• O-rings or interchangeable rings
• Sometimes: bullet vibe, storage pouch, or lube sample

Essential Add-Ons to Consider

While a basic kit covers the essentials, a few add-ons can make your experience more comfortable, versatile, and fun. A high-quality water-based lubricant is a must-have for any strap-on play—it reduces friction and enhances sensation for both partners. If you’re using a silicone toy, avoid silicone-based lube as it can degrade the material.

Another smart addition is a bullet vibrator that fits into a pocket in the harness or sits against the wearer’s body. This provides clitoral stimulation for the person wearing the harness, which can make the experience much more pleasurable. Some harnesses, like the Choose Your Harness | Strap-On Harnesses by New York Toy Collective, are designed with a built-in pocket for this purpose.

• Water-based lubricant
• Bullet vibrator (for wearer stimulation)
• Extra O-rings for different toy sizes
• Cleaning wipes or toy cleaner

What to Look for in a Strap-On Kit: Fit, Material, and Adjustability

Fit is everything when it comes to a harness. Look for adjustable straps that can be tailored to your waist and hip measurements. A good harness should feel snug but not restrictive, and it should stay in place during active play. Leather and nylon are common materials—leather offers a classic, sturdy feel, while nylon is often more flexible and easier to clean.

The dildo’s material matters too. Body-safe silicone is non-porous, easy to sterilize, and hypoallergenic, making it the gold standard. Avoid toys made from jelly or PVC, which can contain phthalates. Also, consider the size and shape of the dildo—if you’re a beginner, a medium size (around 5 to 6 inches) with a slight curve is often a good starting point.

Finally, think about how the dildo attaches. Many harnesses use an O-ring system, which allows you to swap out different toys as long as they have a flared base. If you already own a favorite dildo, check the ring size to ensure compatibility.

• Adjustable straps for a custom fit
• Body-safe silicone dildo
• Interchangeable O-ring system
• Compatible with your existing toys

Beginner Strap-On Kit Contents: What’s Really Necessary?

If you’re new to strap-on play, you might be wondering what you truly need versus what’s just nice to have. The absolute essentials are a harness and a dildo. Everything else—lube, wipes, a vibe—is an enhancement, not a requirement. That said, a bullet vibrator can make a huge difference in comfort and pleasure, so it’s worth considering even as a beginner.

Another thing to keep in mind is the learning curve. Don’t expect perfection on your first try. Take time to adjust the harness, find the right angle, and communicate with your partner. A beginner strap-on kit that includes clear instructions or a simple design will make the process smoother. The Carter Strap-On Kit is a great example of a straightforward, user-friendly option that doesn’t overwhelm you with extras.

• Start with just the basics: harness + dildo
• Add lube and a vibe later if you want
• Read the instructions and practice adjusting the fit

Beyond the Basics: Expanding Your Kit

Once you’ve mastered the fundamentals, you might want to expand your strap-on kit with more specialized accessories. A double-sided suction cup can turn any dildo into a hands-free or double-ended toy, opening up new possibilities for solo or partnered play. It’s a versatile addition that works with many harnesses and dildos.

If you’re interested in temperature play or texture variation, consider adding a second dildo with a different shape or firmness. Some people also enjoy using a pump kit in combination with strap-on play for added sensation, though that’s a more advanced route. The key is to build your kit gradually, based on what you and your partner enjoy.

• Double-sided suction cup for hands-free options
• Second dildo for variety
• Pump kit for advanced play (optional)

A strap-on kit is a fantastic investment for anyone exploring strap-on play. By understanding what’s included, what to add, and what to look for, you can choose a kit that fits your needs and budget. Remember, the best kit is one that feels comfortable, uses body-safe materials, and brings you and your partner joy. Happy exploring!
