STANLEY Flowstate Spring Bottle 591 ml Ash — Slim Insulated Stainless Steel, Leakproof Locking Lid

The STANLEY Flowstate Spring Bottle (20 oz, Ash) is a slim, leakproof insulated bottle built to stay cold, travel light, and fit seamlessly into daily life.

The Flowstate Spring Bottle blends minimalist styling with practical performance for everyday hydration.

Constructed from recycled 18/8 stainless steel with double-wall vacuum insulation, this bottle is designed to endure daily use and maintain beverage temperature for long stretches.

How does the lid keep my drink from spilling?

The bottle uses a locking dual-action lid that prevents accidental openings and keeps the sip spout protected when not in use. A quick-flip button reveals the spout for drinking and the lock secures it shut for transport, making it safe to toss the bottle into a bag without leaks.

• Locking mechanism prevents unintended flips and spills.
• Covered spout stays clean between sips.
• One-handed quick-flip operation for convenience on the move.
