Your Guide to Harness Attachments
Choosing harness attachments should feel simple, not intimidating. Whether this is your first set or an upgrade to a favorite you already own, the right pick comes down to size, material, and how the piece connects to your harness. Nothing about it has to feel technical when you shop, and we keep the language plain so it stays comfortable.
Harness attachments are the interchangeable pieces that slot into a strap-on, so a single harness can offer many different experiences for a couple. Swapping shape, girth, or firmness keeps things fresh without buying a whole new setup every time. That flexibility is exactly why couples love building a small collection.
This guide walks through the main styles and how to match a piece to your harness. We keep it pressure-free from start to finish. If you are new to this, our guide to using a hollow strap-on is a friendly place to start.
Types of Harness Attachments
Harness attachments come in a few friendly families. Classic silicone dildos are the forgiving place most couples start, while dual-density styles pair a firm core with a softer, skin-like outer layer for a more lifelike feel. Realistic and non-realistic shapes both work, so you can pick the look that suits you.
O-ring styles feature a flared base that seats into a standard harness, while vac-style pieces plug into a matching harness socket for a locked-in hold. Hollow designs add extra girth or length for the wearer, which some couples like for added confidence. Slim, petite pieces keep a first try gentle and easy.
Textured and gently curved harness attachments add a little extra sensation, while smooth, straight designs keep everything simple. Sizes range from modest to bold, so you can start small and work up at your own pace. Every piece ships in a plain brown box.
Many couples keep a small library on hand — a slim starter, a lifelike dual-density piece, and a bolder favorite for later. Mixing shapes and sizes is half the fun, and it all works with the same harness. That is the real value of building out your harness attachments over time.
A few favorites to explore: the Revolver Strapless Strap on G Spot Dildo, the Boundless Smooth, and the Boundless Smooth.
How to Choose the Right Harness Attachments
Start with the connection. Most harness attachments use a flared base that seats into a standard O-ring harness, so check that your harness and your piece share the same system before you buy. Matching the two is the single most important step.
Next, decide on size and firmness. A slim, softer silicone piece is the most beginner-friendly, while a thicker or dual-density style delivers a fuller, more lifelike feel. If you are unsure, start smaller — you can always size up later.
Then think about material and cleanup. Body-safe silicone is soft, nonporous, and simple to keep clean, and a little water-based lubricant keeps every piece comfortable from start to finish.
Budget is the final piece, and quality lives at every price here. A simple silicone attachment costs very little, while premium dual-density designs buy more realism and durability. Start with whatever feels comfortable to spend, and add new harness attachments to your collection as you go.

Cleaning, Storage & Discreet Shipping
Body-safe silicone is our default because it is nonporous, gentle on skin, and simple to keep clean — warm water, a mild unscented soap, and a full dry before storage. Pair silicone harness attachments only with water-based lubricant so the surface stays smooth.
Store each piece on its own so nothing rubs together, and give it a quick rinse before and after use. A little routine keeps your harness attachments in great shape for years.
Discretion is built into every order. Your harness attachments arrive in a plain brown box with a discreet billing descriptor, so no one needs to know what is inside — not your roommate, your family, or your nosy neighbor.
