Our Tech
At Aisle, performance is our top priority.
Every layer, material, and construction choice is designed in Canada by our expert design team. Our leakproof technology focuses on what actually matters: protection that works reliably without chemicals, or shortcuts.
BOOST™ Adjustable Absorbency
Protection you can customize
Absorbs 4-8 tampons
Not every day requires the same level of protection. That’s why we developed BOOST™, our adjustable absorbency system.
BOOST™ allows you to customize protection using a removable absorbent BOOSTER™, adding capacity only when you need it.
What is a BOOSTER™
A BOOSTER™ is a removable insert shaped like a pad without wings that is specially designed to fit into our BOOST™ underwear.
How it performs
- Add absorbency for heavier days, overnight wear, or extended use
- Remove it for lighter days and a slimmer feel
- Easy to refresh with new BOOSTERS™ throughout the day
- Can be worn without BOOSTERS for light comfortable coverage
How it works
BOOST™ can be worn without a BOOSTER™ for light coverage or you can add a BOOSTER™ to increase protection on heavy days.
Adjust absorbency by sliding the removable BOOSTER™ into the front and back openings of the gusset.
Why we made it
Adjustable absorbency means better comfort, better performance, and you need fewer products overall.
Super Leakproof
Engineered for Heavy Flow
Absorbs 8 tampons
Our Super Collection is designed for high-absorbency performance during heavy flow days or overnight wear.
The Super Boxer style is designed with even more protection that covers the inner thighs.
How it performs
- Super Collection styles are engineered for reliable heavy-flow protection throughout the entire gusset.
- In styles like the Boxer, leakproof coverage extends down the inner thighs and all the way up the front-to-back.
How it works
Super styles use a higher-capacity absorbent core made from layered, fast-drying technical fabrics, paired with extended front-to-back coverage. Instead of adding bulk, these layers work together to draw moisture away from the body and lock it in—while a thin waterproof barrier prevents leaks.
Why we made it
Some days call for built-in protection you don’t have to think about. We designed the Super Collection for people who need maximum absorbency without add-ons, so performance is always there when flow is consistently heavy.
Better Gussets
Coverage, comfort, and performance
Gussets (the crotch of your underwear) are the foundation of leakproof performance. From materials to shape to construction, we design premium gussets that prevent leaks, extend coverage, and hold up over time.
Extended Coverage
Our gussets are longer and wider to protect the areas most prone to leaks. In styles like the Boxer, leakproof coverage extends all the way from front to back, supporting reliable protection during movement, sitting, and overnight wear.
Organic Cotton Gussets
Our Super and Essential gussets are made with natural fibres selected for breathability, comfort, and long-term wear against the body. These materials help with breathability, supporting comfort and odour control without unnecessary chemicals.
Built to Last
Unlike typical bonded or glued construction, our stitched gussets made with premium materials maintain flexibility and integrity through repeated washing, reducing breakdown over time.
Durability, Wash After Wash
Made with premium fabrics and construction
Our products are designed and tested to maintain absorbency and structure through 100+ machine washes, far exceeding the industry norm of 25-50.
Durability means
- More sustainable
- Consistent protection over time
- Better value per wear
- Products you can rely on, cycle after cycle
Reusable only works when it truly lasts.
Odour Control, Naturally
Breathable Materials, Not Masking Chemicals
Odour control starts with technical and breathable materials—not fragrances or chemical treatments.
By combining natural fibres with fast-drying layers, Aisle underwear helps reduce the conditions that cause odour in the first place.
Our Dri-Release™ absorbent technology combines absorbent and water repellent fibres to optimize wicking and drying to reduce odour.
SAFETY COMES FIRST
Materials You Can Trust
Everything we make is designed for long-term wear against the body.
Our materials are:
- OEKO-TEX® certified
- PFAS-free
- Selected for safety, durability, and skin comfort
Because performance should never come at the expense of health.
Our technology is built with intention—every layer, every seam, every choice.
That’s how we create leakproof underwear that performs better, lasts longer, and feels good to wear.
