BreatheLab is a new activewear brand built around one idea: what you wear while you move shouldn't be harming you.

We're launching Lab One in Summer 2026, with a small, considered range designed to be free of PFAS, phthalates, and the other finishing chemicals hidden in most performance fabrics.

We're taking our time getting it right rather than rushing to shelves.

Most performance fabrics on the market are treated with a cocktail of chemicals to give them properties like stretch, sweat-wicking, odour resistance, and water repellency. Growing research into these "forever chemicals" links them to hormonal, immune, and reproductive issues.

Your skin is your largest organ, and during exercise your pores are open, your circulation is up, and anything sitting against your skin is being absorbed more readily than usual. We think that's worth paying attention to.

BreatheLab exists because we couldn't find activewear that took this seriously, so we decided to build it ourselves.

Lab One will be a small, focused range of core pieces. Leggings, tops, and shorts. Designed to be mixed, matched, and worn hard.

We're launching with a tight edit rather than a sprawling catalogue because every piece has to earn its place through months of testing.

We'll be sharing full product details, prices, and imagery closer to launch through the Lab Notes Newsletter. If you'd like a heads-up, that's where it'll land first.
