Features to consider when choosing a face strap on

The following are the features that will guide you on the most important features to consider when comparing face strap on models to get the one that matches your needs.
Design/construction/type
The best mouth strap on sex toys are available in different designs and varied components. These components also vary in their sizes and complexity so you can choose the one that suits your level of experience. For instance, strap ons used for dominance feature smaller and softer ball gags that are secured with fasteners for beginners. On the other hand, advanced toys for BDSM pros sport leather and metal mouth bits and may include locking functionality as well as buckles for maximum restraint.
Models such as Bondage Boutique Leather and Studs Dildo Gag come with a mouth plate that fully covers the mouth to quiet your partner’s moans as they squirm helplessly; others come with breathing holes or a stopper that can be removed to control breathing; and then there are strap on face dildos with the mouth exposed to keep your mouth fully open or to let you use your tongue. You will also find strap on face dildos that can be inflated to increase their length and girth to your preference. This type is recommended for professionals who are experienced in gagging.
Some accessories included with strap on face dildos are lock rings and pumps for inflatable models. Cuffs, collars, leashes, and other muzzles are widely available for separate purchase.
Dildo size
When comparing dildo sizes, we factor in the girth and insertable length. This typically ranges from 5 inches to a maximum of 12 inches so you can find your preferred size.
We have reviewed the best face dildos ranging in length of 2.5 inches to 5.5 inches. If you are a beginner, we recommend buying smaller sizes that you can upgrade as you gain more experience. For greater flexibility that also saves on cost, consider inflatable models such as Bondage Boutique Inflatable Dildo Gag that are capable of increasing dildo circumference from 3 inches up to 5 inches.
Small ball gags have 1-inch circumference while the ones designed for hardcore BDSM measure between 2 to 3 inches. Make sure you confirm the size, especially if you have just started your bondage journey, to avoid ending up with a size that may obstruct breathing or a tiny one that will be ineffective for gagging.
Materials used
There are different types of materials used in the different parts of a strap on face dildo.
The dildos often feature silicone because it is silky smooth, waterproof, sturdy, and easy to clean. You may even sanitize it. The hypoallergenic material is also tasteless and odorless.
Rubber is preferred for mouth gags because it is soft enough to bite on without straining your jaws, and it does not leave dents because it bounces back. However, its porosity can make cleaning it a hassle.
Latex is less commonly used in face dildos to avoid possible allergic reactions. Faux leather is almost a fixture in the straps of such dildos because you can clean it by wiping it with a damp cloth. Buckles and fastening hooks are usually metallic.
Harness circumference

A loose harness will keep slipping off your face, and a tight one will dig into skin and be uncomfortable to use. Manufacturers provide the range of sizes in the description of their products.
The best mouth strap on would have a strap that can be adjusted to a wide range of sizes to fit most individuals. One of the models we have reviewed extends to a maximum of 28 inches.
Flexible harnesses feature buckle holes, hooks, and fasteners to help you adjust to the right fit.
