Sixer Cooler

The Willow Sixer was born out of the need for a compact, durable, and effective cooler that raised the standard for portable chillers. Its rotomoulded shell offered structural strength and resilience in harsh conditions, while double-walled insulation kept contents cold for extended periods. The design incorporates features like a robust hinge, moulded handles, and secure lid sealing, all in a surprisingly small footprint that made it ideal for daily use. Over time, the Sixer became ubiquitous in Australia, influencing what people expect from plastic coolers. Its enduring presence speaks to how a well-engineered, no-frills design can set the template for an entire category.
