Our tech
Aisle underwear
Aisle underwear have a multi-layered leak proof panel, featuring Truetex™ fabric technology. They'll absorb two tampons worth of menstrual fluid on their own, and up to four tampons worth when you use the absorbency booster.
Quick-wicking mesh top layer
Bonded Truetex™ technology core
Breathable Tencel™️ Organic Cotton
Bonus Booster
Each pair of Aisle underwear come with a bonus absorbency booster. Just tuck the ends of the booster into the pockets at either end of the gusset panel. The pockets are bonded with a silicone free anti-slip tape to help secure the booster in place.
Aisle pads
Aisle pads represent years of fabric research. The result - a cloth pad that feels just like your most comfortable pair of underwear, but can hold up to even your heaviest days.

All about balance
Each one of the materials used in our products is carefully developed to provide superior performance, while maintaining sustainability and comfort. It’s a fine balance, but we think we’ve cracked the code to provide products that really work, without harming the planet.
Our materials
Tencel™
Tencel™ is a fibre harvested from sustainable wood sources. Wood pulp is transformed into soft, silky smooth yarns that are then knit into fabric that has high breathability, is less susceptible to odour-causing bacterial growth, and absorbs 50% more than cotton.
This fibre is certified by:
- Control Union, under the GRS (Global Recycled Standard)
- Oeko-Tex Standard 100
Truetex™
Truetex is a blend of hydrophilic and hydrophobic fibres which creates an inherently wicking and absorbent material at the yarn level, that you would not achieve with a singular fibre type. This intimate blend ensures performance without the need for added chemical finishes. This means that performance does not decrease with multiple washes. Truetex is Oeko-Tex Standard 100 Certified, ensuring that no harmful chemicals are used in dyeing and finishing.
This fibre is certified by:
- Oeko-Tex Standard 100
Recycled Polyester
Plastic waste is a massive environmental issue. It’s said that every piece of plastic ever manufactured still exists to this day. While plastic does eventually degrade, it ends up breaking down into microparticles that are easily swallowed by wildlife, ending up in our food chain and eventually our own bodies.
Part of the solution is reducing the amount of plastic that we throw out, but another important factor is finding a use for all the plastic that’s already been trashed.
Polyester is a super durable, versatile fiber that can create super absorbent fabrics that are perfect for periods - it’s also made from plastic. Luckily, since we have such a big plastic waste problem, we already have all the resources needed to create polyester without making any new plastic.
Our recycled polyester is GRS (Global Recycled Standard) certified, ensuring that only post consumer plastic materials are used, which means that our products are actually helping to remove plastic waste from landfills.
This fibre is certified by:
- Control Union, under the GRS (Global Recycled Standard)
- Oeko-Tex Standard 100
Organic Cotton
Organic cotton is grown without the use of synthetic insecticides, pesticides, or fertilizers. Eliminating exposure to these chemicals has a significant impact on the earth and the health of farm workers and their families. Organic farming techniques preserve topsoil and prevent water pollution from pesticide run-off.
This fibre is certified by:
- Control Union, under the OCS (Organic Cotton Standard)
- Oeko-Tex Standard 100
Technical Cotton
Our performance cotton is made from a blend of water-repellent and absorbent yarns which creates a quick-wicking material that draws fluid away from your body. This blend of yarns dries 50% faster than standard cotton and moves fluid more efficiently than synthetic fabrics. While we haven’t yet been able to source organic fibers, the cotton used in this specially engineered technical material is grown and spun in the USA, then knit and dyed in Montreal, Canada.
Thermoplastic Polyurethane
Absorbency is important, but in order for a menstrual product to be effective, it has to be leak proof. We use a PTFE-free thermoplastic polyurethane membrane to ensure that our products will provide the reliability you expect. Our TPU has a 10k/10K rating, which means it can stand up to heavy flow, while also maintaining breathability.
Other materials
POM snaps - We chose our snaps for durability, accessibility and ease of use. Metal snaps can react with cleaning products, causing fabric damage and the potential for rust, so we opted for POM snaps that are lab tested to be free from harmful substances.
Virgin Polyester- Our pads still use virgin polyester in the absorbent core- for now. We are in the process of finding a reputable supplier and hope to make the change over to recycled polyester later this year.
Lab results
Lab results
When it comes to absorbency, we mean business. Aisle products are lab tested to meet our high standards for absorbency and leak protection.
Underwear hold 4 tampons* of fluid when used with a booster.
Each pad will absorb up to 4 tampons* worth of fluid.
*Absorbency is measured based on the industry standard junior tampon.
