Sweat Towel: What to Look For and Why Most Gym Bags Have the Wrong One

The towel in most gym bags did not arrive there by design. It migrated there from a bathroom cupboard at some point, survived several "I should replace this" thoughts and now lives permanently in the bag alongside a spare hair tie and a protein bar from 2024.

This is fine. It is also why half of the lockers in most Australian gyms have that particular smell by Tuesday afternoon.

Here is what a proper sweat towel actually does and why it is worth upgrading.

The smell problem and why it is not inevitable

Cotton holds moisture inside its fibres. A damp cotton sweat towel rolled up in a gym bag after a session starts developing bacteria within twenty-four hours. By Wednesday it is noticeable. By Friday it is the reason someone at the gym opens a window.

A microfibre sweat towel absorbs fast and dries in one to two hours when aired out after a session. If you take it out of the bag when you get home and hang it anywhere with airflow, it is dry again the same evening.

The zip pocket is not optional

Classic gym scenario: your bag is in a locker. Your phone, your key and your card are in the bag. The bag is now inaccessible because you locked it in the locker with the key. You work through this using a shoe, a front desk person or sheer willpower depending on the day.

The Will and Wind gym towel has a zip pocket for your key, locker coin, earbuds or card. The zip closes fully and stays closed during a set. You wear the towel around your neck and your key is always exactly where the towel is. We wrote about this in why gym towels with zip pockets are a game changer and the response was essentially "obviously yes why is this not standard."

Size: large enough to actually work

A hand towel does not cover a bench. A bath towel takes over the bag. The Will and Wind gym towel at 100cm x 60cm covers a full bench seat, drapes properly over cable equipment and wipes down a machine without needing to be folded into origami. At under 150 grams it takes up almost no bag space.

What the GRS certification means in practice

Each Will and Wind gym towel is GRS 4.0 certified rPET , recycled post-consumer plastic, independently audited annually. Thirteen recycled bottles per towel. The certification is verified by a third party, which matters because a lot of sustainability claims are self-reported. See what is rPET and why it matters for the full story and how to choose the best sustainable towel for beach and gym use for the broader comparison.

FAQs

How often should I wash a sweat towel?

After every use. Cold machine wash, no fabric softener, line dry. Microfibre washed and aired out after a session is dry and fresh again the next morning. Leaving it in the bag damp is the main cause of smell problems.

What is the difference between a sweat towel and a gym towel?

The same thing described differently. A sweat towel manages perspiration during exercise. A gym towel does the same plus wiping equipment. A good gym towel handles both.

Can I use my sweat towel at the beach?

Yes. The microfibre format works at the beach, pool and gym. The gym towel at 100cm x 60cm is compact for a beach towel but works for a quick dry-off. For dedicated beach use the Will and Wind travel towel at 160cm x 80cm is the better size.

Do sweat towels come in designs or just plain?

Will and Wind gym towels come in original Australian ocean photography designs. It is the one gym towel that does not look like it came in a bulk pack for a corporate wellness event.

How do I stop my sweat towel from smelling?

Wash after every use and do not leave it damp in the bag. Microfibre holds onto smell considerably less than cotton when washed regularly. Cold wash, no fabric softener, air dry.
