Bringing your own pilates straps to class is a great idea.
It allows you to be in control of the amount of germs you come in contact with. You can have peace of mind knowing you are the only person that has touched your straps.
Studios will be open to the gesture and some studios will even sell them. If you can't find them at your local studio, you can purchase them online.
There will be different styles of pilates straps, so make sure you check with your studio and find out which style they prefer.
Here are your options:
1. Single loop straps with metal d-ring
2. Double loop straps with metal d-ring
3. Single loop straps with soft ring
4. Double loop ring with soft ring
You will also find that the above options will come with padding and without. This will be a personal choice based on how much comfort you require. For example, if you have arthritis in your hands or feet, you will find the padded version of the straps more comfortable.
