MAMMOTH MUG 2.5L

Used by athletes, nurses, trades workers, and people who are done with small bottles.

Why Most Water Bottles Fail

Most bottles are too small, hard to clean properly, and start to smell within weeks. Narrow necks trap bacteria. Constant refills break your day. The Mammoth Mug 2.5L was built to solve all of it.

Why Mammoth Mug Fixes That

• 84oz / 2.5L capacity — fewer refills, less interruption
• Wide mouth — fit your hand inside, clean it properly every time
• BPA-free, DEHP-free, estrogenic activity-free — full material disclosure
• Built for real use — gym, trades, travel, long shifts

Who This Is For

• Gym users — no mid-workout refills, easy supplement loading
• Trades workers — hydration that lasts the whole shift
• Nurses and healthcare workers — long shifts without refill access
• Drivers and travellers — hours of hydration without stopping

Mammoth Mug vs Stanley, Yeti & Hydro Flask

At 84oz, the Mammoth Mug 2.5L holds more than double a Stanley Quencher or Hydro Flask (both 40oz) — at a better price, with full BPA and DEHP-free disclosure.
