Introducing BASE: Period Underwear for People on the Go

Shortly after launching our signature BOOST period underwear, customers told us they wanted a simpler Booster-free option for lighter flow. Inspired by the trend of at-home workouts during the pandemic, we developed BASE: a line of period underwear that is as comfortable for your sweat sesh as it is for your next Netflix binge. BASE is made to move with you throughout the day, whether you’re WFH or working-out.

Period Underwear Designed for Movement

The wide, athleisure-inspired waistband doesn’t dig in or add pressure to bloated, crampy bellies. The minimal design and soft colors keep things sleek, simple, and grounded. Our seams are still flatlocked for a smooth profile and added durability.

Increased Leakproof Coverage

We kept the same reliable gusset tech from our original BOOST underwear, so you can trust them to absorb your period and keep you leak free. To keep you covered no matter what, we’ve extended the gusset all the way from the front to back waistband, so you can lunge, lean or lounge away.

Sleek, Simple Design

We removed the booster system to simplify your routine and provide a sleeker, no-fuss experience. Even without the Booster system, BASE period undies will absorb up to 4 tampons' worth of menstrual flow - ideal for light to moderate periods, or as a back-up to a cup or tampon. BASE is available in three popular styles, whether you’re looking for a bikini or period thong, in a range of sizes from XS to 5XL.

Sustainable

Sustainability is always top of mind, so we chose a lightweight blend of recycled polyester, organic cotton, and spandex. This new, performance-driven fabric has increased wicking and quick-drying properties to give you the best washable period underwear possible. The breathable construction will keep you comfy and cool throughout any activity. As with all our other fabrics, it is certified STANDARD 100 by OEKO-TEX® and free from harmful substances.

So, whether you need period panties for your workout or just to lounge around, Aisle BASE underwear are your go to choice!
