Apparel brand The Upside has partnered with fitness franchise Strong Pilates to launch a sustainable activewear collection.

The collection features 100 per cent sustainably-focused fabrics with each piece carrying a custom-designed branded artwork including Strong Pilates’ logo.

Strong Pilates is an advocate of sustainability, maintaining a plastic-free environment at its studios.

“As a brand, Strong has always been very clear on its values and goal of feeling stronger both physically and mentally. This collaboration elevates that experience for our trainers and members, reinforcing our commitment to providing the best in fitness and lifestyle,” said Strong Pilates co-founder Michael Ramsey.

Customers may purchase the collection on pre-sale until February 4 on the Strong Pilates website and pick up the order from Strong Pilates studios in Australia, New Zealand, and the UK.
