We Built the Bottle We Couldn't Find

In 2014, Mammoth Mug started with a simple frustration: every water bottle on the market was too small for real daily hydration.

Athletes, nurses, trades workers, and everyday Canadians were all dealing with the same problem — constant refills, narrow openings that were impossible to clean, and bottles that looked great on a shelf but failed in real life.

So we built something different. The Mammoth Mug 2.5L — 84oz, wide mouth, BPA-free and DEHP-free, and designed specifically to handle a full day without needing constant attention.

What We Stand For

• Function over aesthetics. We design bottles that work — not just ones that look good.
• Full material transparency. BPA-free, DEHP-free, estrogenic activity-free, and androgenic activity-free. We tell you exactly what's in your bottle.
• Canadian through and through. Designed in Canada. Shipped from Ontario. Available at Sport Chek and 300+ retail locations nationwide.
