Yes. The Core Collection has been designed to adapt across different environments, including training. Four-way stretch and sweat-wicking properties provide the functionality needed for exercise, while the fit and aesthetic allow each piece to transition beyond it.

The Core collection is designed with a regular, true-to-size fit. We recommend choosing your usual size, or sizing down if you prefer a closer, more fitted look. For detailed measurements, please refer to the size guide on each product page.

We currently deliver across the UK, with plans to expand internationally in the future.

Orders are typically delivered within 2–4 working days after dispatch. Once your order has been dispatched, you’ll receive tracking information by email. We’re also working to introduce next-day delivery in the near future, giving you more flexibility when placing your order.

We select fabrics based on the purpose of each piece, with comfort, aesthetics and functionality at the forefront. Materials will naturally vary by product; however, each is chosen specifically to deliver the right balance of feel, fit and function for how the piece is intended to be worn.
