Born from a love of family and craftsmanship, Billy Bamboo creates accessories designed to bring comfort to everyday life. Founded by designer Jenny Costelloe, Billy Bamboo began as a small family project, lovingly named after her son, Billy. What started as a desire to create something special for her kids soon grew into a brand for the whole family, a collection of timeless pieces that celebrate quality, craftsmanship & colour.

Our knitted accessories are designed with care in our Toronto studio, using natural and durable materials created to last season after season. Each piece, from cozy socks to soft beanies and balaclavas, is crafted to feel good and make ordinary moments more meaningful.

What we make?

We design a considered range of knitted accessories and everyday essentials, with a focus on comfort, function, and longevity. Our collections include socks, beanies, balaclavas, and seasonal knit accessories — thoughtfully designed to be worn daily.

Each piece is developed with attention to yarn selection, construction, and fit, balancing softness with durability. We favour timeless silhouettes alongside natural and bold, vibrant colour tones, creating accessories that feel familiar yet refined, and that move easily between seasons and settings.

Why we make it?

Billy Bamboo was created from a desire to make things better — better feeling, better made, and better suited to real life.

As a family-founded brand, we believe the everyday items you reach for most should be the ones made with the most care. Socks, hats, and cold-weather essentials may be simple by nature, but when they’re well designed and thoughtfully made, they quietly elevate daily routines.

We make products to be worn, loved, and lived in — not overdesigned, not disposable, and not trend-led. Our aim is to create accessories that become part of your rhythm, offering comfort, warmth, and a sense of ease, season after season.

This is what we mean by Products for Life.
