The STANLEY Flowstate Spring Bottle (20 oz) is a slim, insulated, leakproof stainless steel bottle designed for easy grab-and-go hydration.

Compact and lightweight, this 20-ounce Flowstate Spring Bottle from STANLEY blends durable recycled stainless steel construction with practical everyday features.

How does the Flowstate keep drinks cold all day?

The bottle uses double-wall vacuum insulation to slow heat transfer and preserve temperature. That engineered barrier reduces warming from the outside while keeping cold drinks noticeably chilled for hours.

• Double-wall vacuum insulation for extended cold retention
• Rated to keep drinks cold and iced for long periods
• 18/8 recycled stainless steel resists corrosion and flavor transfer

Is the lid really leakproof and easy to use during activities?

Yes — the dual-action locking lid combines a quick-flip sip button with a secure lock to prevent accidental openings. The spout is covered when closed, reducing spills and keeping the drinking area sanitary between sips.

• Locking mechanism prevents unintended flips in bags
• Quick-flip button allows one-handed use on the move
• Covered spout stays clean when stowed

Will this bottle fit into my daily routine and travel gear?

The Flowstate’s slim, tapered profile is engineered for portability and easy handling. Lightweight and narrow, it fits most cup holders and slips into side pockets or bag compartments without adding bulk.

• Slim silhouette fits most car cup holders and backpack pockets
• Attached lanyard simplifies carrying or clipping to a bag
• Cushioned base softens set-downs and reduces noise

How durable and easy to care for is the bottle?

Constructed from recycled 18/8 stainless steel, the bottle is built for everyday knocks and trips. It’s BPA-free and dishwasher safe, making cleaning straightforward and long-term use practical.

• Recycled 18/8 stainless steel for strength and flavor neutrality
• BPA-free materials where they contact beverages
• Dishwasher-safe components for convenient cleaning
