Flat Steel Water Bottle 17oz - Slim Leak Proof Travel Bottle

In this review the DRNK Steel flat water bottle stands out as a practical choice for people who need a slim, durable bottle for commuting, light travel, gym bags or office desks. The single biggest reason to buy is its unique slim profile: at 500ml and under 3 cm deep it fits into narrow sling bags and briefcases where round bottles do not. The reviewer found it well made from food grade stainless steel with a spill proof cap that stays attached and keeps pockets dry, making it a dependable everyday carry item.

Key Features

• Slimmest shape: The less-than 3 cm depth design allows the bottle to slide into slim bags and small compartments that traditional bottles cannot reach.
• Premium 304 stainless steel: Food grade, powder coated steel resists rust and corrosion for long lasting use and a clean taste.
• BPA free construction: Made without bisphenol chemicals so the bottle is non-toxic and safe for daily hydration.
• Spill proof safety cap: A cap attached to a silicone loop prevents misplacement and reduces the chance of leaks in a bag.
• Lightweight durability: The high quality steel construction balances sturdy build with portability for active use at work, gym or hiking.
• Proven design: As a product showcased on Shark Tank, it carries third party recognition for its design and concept.

Who It's For

This bottle is ideal for commuters, office workers, and anyone who carries a small sling or messenger bag and needs a leak proof, compact hydration solution. The flat profile is especially useful when bag width is limited or a bottle must sit flush against other items without rolling.

People who want very wide openings for large ice cubes or who need multi-liter capacity should look elsewhere, since the 500ml capacity and narrow mouth limit ice insertion and very long outings without refilling.

Pros & Cons

Pros

• Non-toxic, bisphenol-free finish for safer daily use.

Cons

• Narrow mouth makes adding large ice cubes difficult for those who prefer very cold drinks.
• 500ml capacity may be small for extended hikes or long travel days without refills.
