What's the Best Underwear Fabric for Sensitive Skin?
For sensitive skin, soft, breathable natural fibers — cotton especially — are the usual recommendation. Breathable fabric lets air move and absorbs moisture, which keeps the skin drier and reduces the warm, damp conditions that can cause irritation. Smooth seams (or seamless construction) also help, since rough seams and tags are a common source of rubbing.
A few things that tend to help sensitive skin: a high proportion of soft natural fiber, a smooth or seamless finish, a gentle fragrance-free detergent, and skipping fabric softener, which can leave a coating some skin reacts to. Washing new underwear before first wear is a good habit too. These are general comfort tips, not medical advice — if you have persistent irritation, a rash, or a skin condition, see a professional, since the cause may need real evaluation. More in is cotton underwear better.
