DRNK Steel Flat Water Bottle 17oz (500ml) - Slim, Leak Proof

In this review of the DRNK Steel flat water bottle, the bottom line is simple: this is for anyone who needs a truly slim, durable reusable bottle that tucks into tight spaces. Our review finds the single biggest reason to buy is its exceptional slimness and carryability - at under 3 cm depth for the 500ml size it fits into laptop bags, purse pockets, and seat pockets where round bottles will not. The bottle is also made from food-grade 304 stainless steel and includes a spill proof cap attached to a silicone loop, which together make it a practical everyday companion.

Key Features

• Slimmest profile: At under 3 cm depth the flat design slides into tight compartments and pockets that traditional bottles cannot reach.
• Premium stainless steel: Made from food-grade 304 stainless steel with a powder coat, it resists rust and stays durable through daily use.
• Bisphenol-free finish: The bottle is fashioned without bisphenol materials, reducing exposure to unwanted chemicals while storing drinks.
• Spill proof cap: A safety cap attached to a silicone loop prevents misplacement and helps keep the mouthpiece clean while making it easy to carry.
• Lightweight and durable: The construction balances durability and weight so it is convenient to carry for commute, gym, or travel.
• Recognized design: Shown on Shark Tank, the bottle is trusted for its design and practicality by industry experts.

Who It's For

The DRNK Steel flat water bottle is best for commuters, travelers, and anyone who carries a slim work bag or laptop sleeve and wants a bottle that won't add bulk. It is ideal for office professionals, students, and gym-goers who value neat packing and a stylish, space-saving shape.

People who need very large capacities for long outdoor adventures or those who prefer insulated bottles that keep drinks hot for hours should look elsewhere; this 500ml flat bottle prioritizes slim carry and portability over maximum volume or extended hot retention.
