While most, if not all, other clothing claiming to be repellent are made with petroleum-based synthetic materials (nylon, polyester, etc.), Ably® Apparel is 100% natural premium cotton, no synthetics and no nanoparticles. Filium®, our trade secret patent-pending technology, allows us to create natural fabrics and clothing that repel stains, liquids and odors, and have them retain the natural feel, soft touch, and breathability that most of us prefer.

The core technology of Filium® is manufactured in accordance with Bluesign® standards for sustainably. Filium® does not contain any nanoparticles, silver, or harmful chemicals that can leach into your skin.

Bluesign® is a leading supply chain transparency and sustainability system for the textile and chemical industries. It audits and certifies companies involved in material production to ensure they meet strict standards for consumer safety, environmental protection, and responsible resource use.

Materials are evaluated based on rigorous criteria designed to minimize harmful impacts on people and the planet while promoting safer chemical management.

To become a Bluesign® system partner, a brand must demonstrate full supply chain visibility, implement a verified social and labor compliance program, and operate a qualifying chemical management system. Ably/Filium is a certified Bluesign® system partner.

The Bluesign® designation indicates that the item was manufactured using processes that reduce environmental harm, limit hazardous substances, and prioritize worker and consumer safety.

Oeko-Tex® Standard 100 is a globally recognized, independent testing and certification system for textile raw materials, intermediate, and finished products. It ensures that products are free from harmful substances and safe for human health, checking for over 1,000 chemicals based on strict, annually updated scientific criteria.

Though not designed specifically to treat hyperhidrosis (a medical condition involving excessive sweating), Ably apparel has become a go-to choice for many customers who experience heavy perspiration.

Thanks to Filium® technology, sweat does not stand a chance. Ably garments do not show sweat marks as easily, dry significantly faster, and resist odor buildup—even with repeated wear. This can make a meaningful difference for customers who want to feel more confident in everyday situations, whether at work, while traveling, or during long days on the move.

Many customers with hyperhidrosis tell us they rely on Ably because it stays presentable longer, feels lighter against the skin, and doesn’t hold onto moisture the way traditional cotton or synthetic blends often do. While Ably does not stop the body from producing sweat, it helps manage the visible and sensory effects of sweating—making clothing feel fresher and more comfortable throughout the day.

Is Ably® Apparel absolutely perfect? Of course not, nothing is. It probably will absorb dirt, charcoal, or anything else for that matter if it is rubbed or ground into the garment. Since that is not a particularly likely scenario, we can say that if you do accidentally spill wine, coffee, or other liquid on your pristine Ably® tee shirt or hoodie, it’s probably a good idea to sprinkle a few water drops on it, or just flick it off.

Ably® Apparel has been wear- and performance-tested for several years now, both in-house and by independent labs. We’ve also had some folks wear Ably® tee shirts in the gym for a month, and for more than a week at a time in hot and steamy places like Cuba and India. They were all astounded that their shirts stayed odor and stain free.

As such, Ably® tee shirts and hoodies will need to be washed only infrequently (as little as once or twice a month), depending on just how much it has been worn and for what use.

The apparel industry estimates that cotton garments have an average life of 30 to 40 washes. Since you don’t need to wash your Ably® tee shirt or hoodie as often as other clothing, and if you follow our care instructions when you wash, we estimate that your Ably® garment’s superior stain/odor/liquid resistant properties should last you for an even longer period of time.
