Ice Shaker and Oxygen Esports announced a partnership where Ice Shaker becomes the official Performance Bottle and Shaker Partner of Oxygen Esports, the Boston Uprising and the newly announced Boston Call of Duty League franchise.

This announcement is an expansion of the partnership between Oxygen and the Gronkowski family, which will provide equipment and performance consulting for OXG rosters.

Ice Shaker, is the creation of the Gronkowski brothers (five pro athletes from the National Football League and Major League Baseball) who needed a bottle to perform for them while on their respective fields of play. The bottle is forged from kitchen-grade stainless steel that will not absorb odor and features a patented twist-in agitator that breaks up powders but is silent when the bottle is shaken.

“Gamers need a bottle that will keep their drinks cold all day, won’t spill, won’t sweat and can mix their favorite energy drinks,” said Chris Gronkowski, Founder and CEO of Ice Shaker. “Ice Shaker is the perfect gaming bottle, and we are excited to see OXG stay hydrated with a bottle that was built for the best.”

Oxygen Esports is New England’s largest esports organization with rosters in esports, including Call of Duty, Overwatch, Valorant, Halo, Rainbow Six: Siege, Rocket League, and Apex Legends.

“We are elated to expand our partnership with the Gronkowski family and welcome Ice Shaker as a partner for all of our rosters,” said Murphy Vandervelde, co-founder, Oxygen. “With most of our leadership team having played collegiate and professional athletics, we know how important it is to equip our athletes to perform in-game, during practice and off the stage.”

Ice Shaker bottles also feature customizable bottle designs and design profiles.

“Ice Shaker’s highly customizable design will allow us to offer our fans plenty of unique and limited-edition colorways enabling them to stay fresh and hydrated,” said Adam Morrison, chief operating officer, OXG.
