Hydraful 64 oz Insulated Tumbler with Handle and Straw — 18/8 Stainless Steel, Leak-Proof Travel Mug

Hydraful's 64 oz insulated tumbler is a large-capacity, double-wall stainless steel travel cup with a soft-grip handle, leak-proof 2-in-1 lid, detachable silicone base, and straw for all-day hydration.

This oversized 64-ounce tumbler is built for long days, long workouts, and outdoor adventures when you want one reliable bottle to hold enough water, smoothies, or iced coffee. Constructed from 18/8 stainless steel with double-wall vacuum insulation, the cup balances durability with temperature control and is designed to be sweat-free on the outside. The wide mouth, ergonomic handle, and dishwasher-safe finish make it a practical choice for everyday use as well as travel, gym sessions, and camping trips.

How does the Hydraful tumbler keep drinks hot or cold?

The tumbler uses double-wall vacuum insulation combined with quality 18/8 stainless steel to reduce heat transfer, preserving cold for extended periods and keeping hot beverages warm. Its sealed lid improves thermal performance by limiting air exchange.

• Double-wall vacuum insulation for long-lasting temperature control
• 18/8 stainless steel construction resists corrosion and impact
• Sweat-free exterior so it won’t leave rings on surfaces
• Lid design reduces heat/cold loss when closed

Is the tumbler truly leak-proof and easy to drink from?

The Hydraful lid combines a sipping spout with a flip-top feature to support both gradual sipping and larger gulps, while seals and locking components make it 100% leak-proof when closed. The included straw keeps sipping convenient on the move.

• 2-in-1 lid: sip spout plus flip-top for varied drinking styles
• Leak-proof seals for no spills during transport
• Reusable straw for hands-free sipping during activity
• Flip-top locks securely to prevent accidental openings

How comfortable and practical is the tumbler for everyday use?

A molded soft-grip handle gives a secure, comfortable hold whether carrying full weight or grabbing it between errands. The wide mouth simplifies filling, adding ice or fruit, and makes hand washing easier.

• Ergonomic soft-grip handle for a reliable, comfortable hold
• Wide-mouth opening fits large ice cubes and fruit slices
• Detachable anti-slip silicone base stabilizes placement on surfaces
• Dishwasher-safe design keeps maintenance simple

What size and use cases work best for a 64 oz bottle?

With a 64-ounce capacity, this tumbler suits anyone who prefers fewer refills: long commutes, day hikes, gym sessions, or desk use where you want to hit hydration goals. Its size is designed for sustained outings rather than small cupholders, so check your vehicle or bag dimensions before purchasing.

• 64 oz capacity reduces refill frequency throughout the day
• Great for long workouts, travel, camping, or office desks
• Secure lid and base make it travel-friendly despite its size
• Not intended for tight car cupholders — measure ahead if needed

Who is this for? This Hydraful 64 oz insulated tumbler is ideal for people who want one durable, high-capacity drink container: athletes, outdoor enthusiasts, busy parents, and anyone tracking daily water intake. If you need rugged insulation, a comfortable handle, and a leak-resistant lid in a reusable stainless-steel cup that’s easy to clean, this tumbler fills that role without fuss.
