WHAT

The Cool Gear brand is known for straying from the conventional to give consumers solutions they want, with a little something extra. As customer demands shifted Cool Gear looked to adapt the original design of their EZ FREEZE reusable water bottles.

NEEDS

“Our core audience uses our reusable water bottles in many different settings, from fairly tame uses in the home and office to high impact outdoor activities. Design flexibility and clarity are benefits that were crucial with any new material, but so is durability. ” explained Hank Roth of Cool Gear. “Our original design of the EZ FREEZE line was made using polycarbonate, but the recent swing in market demand toward BPA-free alternatives prompted us to seek out a partner that could give us similar – or better – product attributes bolstered with the marketing power of the BPA-free stamp of approval. What we got with Tritan™ was a solution with the same functional benefits as polycarbonate plus so much more,” Roth added.

MATERIAL

In addition to design flexibility, Tritan™ provided impressive chemical resistance characteristics and low residual stress compared to polycarbonate. “When comparing Tritan™ to polycarbonate – apples to apples – we saw so many clear advantages to Tritan™, there was no contest,” Roth explained.
