Linen vs Cotton Towels: Drying and Durability

The Short Answer

Linen and cotton are both natural fibers used in sauna towels, but they behave very differently in a hot, humid environment. Linen dries quickly, resists odor, and becomes softer every time you wash it. Cotton is highly absorbent and feels plush, but it stays wet for a long time, which makes it more prone to mildew and a musty smell in a sauna locker.

For regular sauna use, linen is the stronger choice. Its hollow fibers allow air to circulate, so it pulls sweat away from your skin and releases it into the air. Cotton, by contrast, traps water in its thick loops. If you prefer a soft, cushy towel and do not mind waiting for it to dry, cotton can still work, especially if you use separate towels for the bench and for drying off.

Absorbency and Feel

Cotton is famous for its absorbency. A thick cotton towel can soak up a large amount of water, which feels satisfying after a heavy sweat. The downside is that cotton holds that moisture inside the fibers, so it stays damp for hours. Linen, on the other hand, has a looser weave and a slightly stiffer texture at first, but it still absorbs moisture efficiently. More importantly, linen wicks water away from your skin and lets it evaporate, keeping you drier and more comfortable.

In a sauna, you typically move between hot benches and cool rinses. A towel that dries quickly between uses helps you stay comfortable and reduces the chance of bacteria growth. If you choose cotton, look for a towel made from long-staple fibers, which are softer and more durable. For linen, the texture softens with each wash, so the initial stiffness does not last.

Drying Speed and Moisture Management

The biggest practical difference between these two fabrics is drying time. Linen fibers are hollow and allow air to pass through, so a linen towel can dry in about half the time a cotton towel needs. This matters if you use the sauna several times a week or if you have to store your towel in a small, humid space. A damp cotton towel can develop a sour smell within a day, while linen is less likely to hold onto odors.

To keep your towel fresh, hang it loosely rather than folding it. In a sauna environment, proper ventilation is key. After your session, wring out the towel and drape it over a bar or hook so air can reach both sides. If you use a linen towel, you might find it is ready for the next session by the time you return, whereas a cotton towel may still feel cold and damp.

Durability and Care Over Time

Linen is one of the strongest natural fibers, and it becomes softer and more supple with each wash without losing its shape. Cotton is durable, too, but heavy looped cotton towels can compact over time, especially if you use fabric softener or high heat. This reduces their absorbency and makes them rough. Linen, by contrast, does not have loops, so it stays breathable and dries quickly even after many wash cycles.

To extend the life of either fabric, wash it with mild detergent in cool or warm water. Avoid bleach and fabric softener, which break down natural fibers. Linen can be line-dried or tumbled on low; cotton can usually handle a medium tumble. If you use a cotton towel, do not leave it in a damp pile after washing, as this invites mildew that is hard to remove.

Which Should You Pick?

If you want a towel that dries fast, packs small, and lasts for years, choose linen. It performs well in the heat and humidity of a sauna and stays fresh between uses. Cotton is a fine choice if you prioritize a soft, thick feel and you are careful to dry it thoroughly after each session. Many sauna bathers end up using both: a cotton towel to lie on the bench for comfort, and a linen towel to dry off afterward.

Think about your routine. If you use a sauna every day, linen will save you time and reduce the risk of musty odors. If you use it occasionally, cotton may be acceptable, especially if you can hang it in a well-ventilated area.

Care Routines for Each Fabric

Cotton towels should be washed in hot water to remove sweat and bacteria, but skip the fabric softener to keep the loops absorbent. Tumble dry on medium and remove them promptly to avoid wrinkles. Linen should be washed in cool or warm water, then hung to dry. Pressing linen while it is still slightly damp can give it a crisp, smooth look, though this is optional for sauna use.

After every sauna session, rinse your towel in clean water and squeeze out excess moisture. This simple step prevents salt buildup and keeps the fibers fresh. If you use a towel on the sauna bench, wash it more frequently, as it will absorb a lot of sweat. For tips on keeping your sauna accessories clean, see our article on towel on bench hygiene.

What to Look for in a Sauna Towel

Size is the first thing to consider. A larger towel, around 55 inches long, gives you enough coverage to sit on and can be wrapped around your waist. For linen, a mid-weight fabric around 170 grams per square meter is a good balance of absorbency and drying speed. For cotton, a higher GSM, such as 600 or more, feels plush but will take significantly longer to dry.

Look for a towel with a hanging loop or a corner seam that makes it easy to drape on a hook. Some sauna bathers prefer a darker color to hide sweat stains, while others like light-colored towels to see how clean they are. The weave is also important: a waffle weave in linen encourages air flow, while a terry weave in cotton holds more water. Choose the one that matches your comfort and maintenance preferences.

Final Tips for Sauna Towel Use

Bring at least two towels if you use a traditional sauna: one to sit on and protect the wood, and one to dry off after your cool-down. Use a dedicated bench towel to absorb sweat, and a separate towel for your body to avoid spreading bacteria. After your final rinse, pat yourself dry rather than rubbing, which is gentler on your skin and helps preserve the towel's fibers.

Linen works well for both roles because it dries quickly and does not stay damp. If you prefer cotton, consider using a cotton towel for the bench where you want extra cushioning, and a linen towel for drying your body. This combination gives you the softness of cotton and the fast-drying performance of linen. For more on what to wear and bring, check our guide on what to wear in traditional sauna.

Questions

Can I use a linen towel in an infrared sauna?

Yes. Linen dries quickly and is comfortable in any type of sauna, including infrared, because it wicks moisture away from the skin.

How often should I wash my sauna towel?

Wash your sauna towel after every session, or at least every two or three sessions if you hang it to dry thoroughly between uses. Frequent washing prevents odor buildup.

Does linen shrink in the wash?

Linen can shrink if you wash it in hot water or dry it on high heat. Use cool or warm water and hang dry to preserve its size.

Why does my cotton towel smell after sauna use?

Cotton holds moisture and can develop mildew if it stays damp. Hang it in a well-ventilated area and wash it regularly to avoid musty smells.
