40th Anniversary Custom YETI Rambler® Tumbler

Celebrate four decades of billfish conservation with a limited-edition custom YETI, created exclusively for The Billfish Foundation’s 40th Anniversary (1986–2026).

This bold red Rambler® features the iconic YETI durability you know and trust, customized with our official 40th Anniversary mark — complete with the billfish silhouette and commemorative crest honoring 40 years of science, advocacy, and global impact.

Built from kitchen-grade stainless steel with double-wall vacuum insulation, it keeps your coffee hot on early tournament mornings and your drinks ice-cold long after lines are in. The MagSlider™ lid adds an extra layer of protection to help prevent splashes while you’re on the boat, at the office, or on the road.

Whether you’re supporting our satellite tagging initiatives, celebrating 40 for 40, or simply raising a glass to the future of billfish conservation, this tumbler is a daily reminder that you’re part of something bigger.

• Official TBF 40th Anniversary custom engraving
