Fine merino wool
Clothing made from very fine merino wool fibers, such as base layers, shirts, and socks.
Why it helps
Fine merino resists odor and bacterial growth, wicks moisture, and stays comfortable when damp. That makes it useful for active, sweaty, or long-wear days.
Look for
- Fine or ultrafine merino (soft, not scratchy)
- Next-to-skin base layers and socks
- Blends with a small amount of stretch for fit
- Flat seams and soft tags
- Machine-washable labels
Avoid
- Coarse or itchy wool right on the skin
- Wool that you wash with harsh, scented detergents
Caution
Coarse wool can itch or irritate, so choose fine merino and test a small piece first if your skin is sensitive or eczema-prone.
