Base layers are your first line of defense against cold and moisture, and after a long day on the slopes, they can end up smelling like it. The good news is, you don’t have to toss them out when the funk sets in. With a bit of care, you can refresh your base layers, extend their life, and keep them feeling soft and comfortable.

Why Do Base Layers Get Smelly?

Base layers are designed to wick sweat away from your skin, but that moisture can also trap oils and bacteria in the fabric. Left untreated, this can lead to odors that survive even a regular wash.

How Do I Wash Base Layers?

Use a mild, sport‑specific detergent that’s designed for synthetics or merino wool. Avoid fabric softeners, bleach, or harsh detergents because they can clog the fabric and reduce its moisture‑wicking ability. Wash your base layers on a gentle or cold cycle, and air‑dry whenever possible.

What If the Smell Doesn’t Come Out?

Try a vinegar soak before washing. Mix one part vinegar with four parts cold water and let your base layers soak for 30–60 minutes. This can help neutralize stubborn odors before washing.

Can I Put Base Layers in the Dryer?

It’s best to air‑dry base layers to preserve their elasticity and moisture‑wicking properties. High‑heat drying can break down fabrics, making them less effective over time.

How Do I Store Base Layers?

Make sure your base layers are completely dry before putting them away. Store them in a breathable space, like a drawer or closet. Avoid leaving them in a damp gear bag, as this can lead to musty odors.

Pro Tip

Base layers are an investment in comfort. A little routine care goes a long way: wash them properly, treat odors as soon as they arise, and store them in a clean, dry space. Do this, and your base layers will stay fresh, soft, and ready for many seasons to come.
