Compare the 34oz Bottle with Grip Lid and 25oz Original Bottle with Straw Lid to find the right frank green size for your hydration needs.

Quick answer

The 34oz Bottle with Grip Lid holds 1,000ml (34oz), while the 25oz Original Bottle with Straw Lid holds 740ml (25oz). The 34oz is better for all-day hydration at the gym or office, and the 25oz is more portable for short trips. Your choice depends on how much you drink and how you carry it.

Capacity and size differences

The 34oz Bottle with Grip Lid offers 1,000ml capacity, while the 25oz Original Bottle with Straw Lid holds 740ml. That's a 260ml difference—enough for an extra glass of water. The 34oz is taller and wider, so it may not fit in smaller cup holders or side pockets. The 25oz is more compact and fits most standard cup holders, making it easier to carry in a bag or car.

Materials and insulation

The 34oz Bottle features triple-wall vacuum insulation and a nano ceramic lining that prevents metallic aftertaste. It's made from over 90% recycled premium stainless steel, so it keeps drinks cold for hours. The 25oz Original Bottle is made from durable, lightweight Tritan plastic, which is BPA-free and a sustainable alternative to single-use plastic. It doesn't have vacuum insulation, so it won't keep drinks cold as long, but it's lighter to carry.

Lid and drinking experience

The 34oz comes with the Grip Lid, designed for optimum flow and easy handling. The 25oz pairs with the Straw Lid and includes a reusable stainless steel straw, which is convenient for sipping on the go. If you prefer a touch-free, one-handed option, the Flip Straw Lid with Strap & Straw (sold separately) fits the 34oz and adds a flip-up mouthpiece with a soft silicone tip.

Trade-offs at a glance

  • Capacity vs portability: 34oz holds more but is bulkier; 25oz is smaller and easier to carry. Choose 34oz for long days, 25oz for short commutes.
  • Insulation vs weight: 34oz is triple-wall insulated and heavier; 25oz is uninsulated and lighter. If you need cold drinks all day, pick 34oz.
  • Lid type: 34oz comes with Grip Lid; 25oz comes with Straw Lid. Both are easy to use but suit different drinking styles. Consider if you prefer sipping or gulping.
