NudeFit FlexCurv Adjustable Strap-On Harness by Together is a unisex, fully adjustable strap-on harness designed for waist sizes up to 68 inches. Constructed from vegan leather and soft polyester materials, it features three interchangeable silicone O-Rings (1.25", 1.75", and 2" diameter) to accommodate different dildo sizes. The through O-Ring design supports double-ended and heavier dildos, making it suitable for partnered play with various penetrative toys and exploration styles.
The harness works by securing around the waist with adjustable buckle straps that accommodate waist sizes up to 68 inches. The through O-Ring design passes through the front of the harness, creating a connection point where you insert your chosen dildo. Three interchangeable silicone O-Rings allow you to match the ring size to your dildo's diameter, ensuring a secure, stable fit that won't slip during partnered penetration.
Vegan leather and polyester construction creates a durable harness that maintains its shape through repeated use and cleaning. The soft material against skin reduces chafing during extended wear, while the adjustable design means the harness grows or shrinks with you rather than requiring replacement. For those interested in expanding their penetrative options, our targeted dildos collection offers compatible choices in various sizes and textures.

Pairing the harness with textured dildos adds sensation layers that smooth insertions cannot provide. Many partners find that combining different O-Ring sizes across sessions allows them to gradually explore thicker penetration without forcing progression. The through O-Ring design also works with double-ended dildos, where one end penetrates your partner while the other end provides stimulation to the wearer—a configuration that creates simultaneous pleasure for both partners.
After use, wipe the harness with a warm, damp cloth and allow it to air dry completely before storing. The vegan leather exterior wipes clean easily, while the silicone O-Rings can be removed and washed separately with mild soap and water. Store the harness and O-Rings in a cool, dry place away from direct sunlight, and keep the three rings together in a pouch or container so they don't get lost. Check the buckle mechanism periodically to ensure the locking clasp still clicks securely.
Non-porous vegan leather and polyester construction creates a harness that resists bacterial growth and cleans thoroughly without absorbing moisture. The silicone O-Rings are body-safe and compatible with water-based lubricants, making them suitable for use with silicone or glass dildos. Polyester and PU materials remain durable through repeated use and cleaning, so the harness maintains its structure and security rather than degrading like lower-quality alternatives.
This harness suits partners exploring penetrative play who want adjustable fit without complex fastening systems. It appeals to people with diverse waist sizes, including those who find standard strap-on harnesses either too loose or impossible to secure. Those seeking to try different dildo sizes and weights benefit from the three interchangeable O-Rings, which accommodate exploration without requiring multiple harnesses. The vegan leather material appeals to those prioritizing cruelty-free options over traditional leather harnesses.
For couples who have struggled with strap-on harnesses designed for single dildo sizes, discovering that three interchangeable O-Rings accommodate different widths transforms how they approach penetrative exploration. Rather than committing to one thickness and hoping it works, the ability to swap rings means gradual progression becomes possible—starting with narrow toys and moving to thicker options as comfort builds. For partners where one person has a larger waist size, the 68-inch adjustment range removes the frustration of standard harnesses that don't fit or require constant readjustment. The through O-Ring design means dildos stay centered and stable instead of rotating or shifting during penetration, creating confidence that enables focus on pleasure rather than logistics. Many discover that reliable harness fit transforms strap-on play from awkward positioning into genuine intimacy.
Our independent testers evaluated the harness's buckle security, O-Ring stability with different dildo weights, comfort during extended wear, and material durability through repeated cleaning cycles. The adjustable buckle maintained consistent tension across multiple size ranges, and the through O-Ring design held standard silicone dildos without slipping during simulated penetration.
Testers noted that the vegan leather felt soft against skin during 30-minute wear sessions, and the three O-Ring sizes accommodated toys ranging from narrow to significantly thicker options without gaps or instability. Individual results may vary based on anatomy, sensitivity, and usage.
