I just bought a few different types of binders. I was wondering if anyone had any heat rash issues with them? I work outside in the heat, and I know Ive had issues with bras and heat rash. How does one prevent heat rash?
Not sure what you've tried so far but this might help. Sweating and skin irritation If a binder's material doesn't breathe or wick away sweat, you can end up with sores or rashes on your skin. One way to minimize this risk is to apply a non-irritating body powder to your skin before binding. Another is to wear a thin undershirt beneath your binder that is made of fabric that wicks away sweat. This can help absorb moisture and prevent irritation that may arise from scratchy binding materials. Remember to allow your skin some time off from binding, and keep your binders clean.
