Nylon chastity cages are lighter and feel warmer against the skin, which suits beginners and long wear. Metal cages, usually stainless steel, are heavier and start off cold, but they're the most durable and the easiest to clean thoroughly. The right choice depends on how long you plan to wear it, how much weight bothers you, and how you'll look after it.
Nylon vs metal at a glance
| Nylon | Metal (stainless steel) | |
|---|---|---|
| Weight | Very light | Noticeably heavier |
| Feel | Close to body temperature | Cold at first, then warms up |
| Long wear | Easy to forget you're wearing it | The weight can be tiring over long periods |
| Cleaning | Warm water and mild soap; check the maker's advice before using heat | Non-porous, can usually be boiled or sterilised |
| Durability | Strong for its weight, can scuff over time | Very durable, lasts for years |
| Under clothes | Light and low-profile | Heavier, so more noticeable |
| Airport security | Usually fine, though locks may have metal parts | Will set off metal detectors |
| Price | Usually more affordable | Usually more expensive |
Why choose nylon
Weight is the main reason. A light cage pulls less, moves less and is easier to forget about, which matters most when you're wearing it for days at a time, during a challenge like Locktober for example. Nylon also stays close to body temperature, so there's no cold shock when you put it on.
The trade-off is care. Nylon needs gentle cleaning, and some nylon cages have a slightly textured surface that takes a little more scrubbing to keep fully clean. Check yours regularly for scuffs or cracks, and replace it if the surface starts to break down.
Why choose metal
Stainless steel is non-porous, very hard-wearing and can usually be sterilised in boiling water, which makes hygiene simple. It also feels solid, which some people prefer.
The downsides are weight and temperature. A heavier cage can become uncomfortable over long periods, and metal will set off metal detectors, so it's harder to travel with.
What about resin and silicone?
- Resin cages are rigid and light, similar to nylon. They're often 3D printed and come in more shapes and colours.
- Silicone cages are soft and flexible. They're comfortable, but less secure than rigid materials.
Which is best for beginners?
Most beginners find a lightweight nylon or resin cage easier to get used to. Whatever the material, fit matters more: a cage that's the wrong length or a ring that's too tight will be uncomfortable no matter what it's made of. Use our size guide to find your length and starting ring before you choose.
How to clean each type
Nylon: wash with warm water and mild, unscented soap before first use and after every wear. Use a soft brush for vents and seams, rinse well and let it dry completely. Don't boil it or use harsh cleaners unless the maker says it's safe.
Metal: wash the same way. Most stainless steel cages can also be sterilised in boiling water. Dry fully, especially around the lock.
What to look for, whatever the material
- A smooth finish with no sharp edges or rough seams
- Clear inside measurements, so you can choose the right length
- More than one ring size, so you can adjust the fit
- Cleaning instructions from the maker
Stop wearing any cage that causes pain, numbness, swelling or skin irritation. This guide is general information, not medical advice.
