Rambler 18oz Bottle with Flip Chug Cap

For shorter runs, day hikes, or desk duty, the Rambler 18oz Flip Chug is our pick when you need hydration fast and hands mostly free. Vacuum insulation holds temperature for hours in Southern summer heat, while the one-hand Flip Chug Cap opens and flows without unscrewing or fumbling. At 18oz, it tucks into a vest pocket without the bulk.

• Flip Chug Cap opens one-handed and seals completely shut — no leaks when closed, no flow restriction when open
• Double-wall vacuum insulation keeps drinks cold for hours even in high heat and humidity
• 18oz size fits most running vest pockets and hydration sleeves without adding unnecessary weight or bulk
• 18/8 stainless steel resists dents, holds no odors, and won't transfer flavors between fills
• Available in Tropical Pink and Royal Blue — both easy to spot on a crowded aid station table or in a packed bag
