Getting the Right Fit with the SpareParts Joque Cover Harness
The SpareParts Joque Cover Underwear Harness is a versatile, adjustable strap-on that combines the look of underwear with the function of a harness. Getting the fit right is key to comfort and security during use. This guide walks you through sizing, adjustments, and the new interior strap feature.
Sizing the Joque Cover Harness
The Joque Cover is available in two sizes: Size A and Size B. Each size has specific waist and leg strap measurements. Size A fits waist 20–50 inches (50.8–127 cm) and leg straps 10–16 inches (25.4–40.64 cm). Size B fits waist 35–65 inches (88.9–165 cm) and leg straps 14–24 inches (35.56–60.96 cm). Measure your waist and upper thigh circumference to choose the right size. If you're between sizes, consider which measurement is closer to your body.
Adjusting the Straps for Comfort and Security
The harness features adjustable locking leg straps and a belt secured with Velcro plus a secondary locking pull feature. Start by loosening all straps, then put the harness on like underwear. Tighten the leg straps evenly so they are snug but not digging in. The belt should sit comfortably at your natural waist or hips—adjust the Velcro closure to your preferred tightness. The secondary locking pull adds extra security so the belt won't slip during activity.
Using the Interior Strap for Extra Security
A new addition to the Joque Cover is an interior strap that wraps around the lower portion of select attachments. This provides extra security for pack and play. If you're using a dildo that has a flared base or a shape that can be secured by this strap, thread the attachment through the O-ring first, then wrap the interior strap around the lower portion. This helps prevent the toy from shifting or slipping out during use.

Material and Care Notes
The Joque Cover is made from high-quality nylon/spandex with wicking elements that draw moisture away from the body. It is hand or machine washable—check the tagless care labels for specific instructions. The materials are water-friendly, so it can handle some moisture, but avoid soaking or using fabric softeners that could break down the elastic. The harness is suitable for those with a vegan lifestyle.
