• COLLAPSIBLE WATER BOTTLE: Flexible bottle shrinks as you drink to help reduce sloshing, bouncing, and bulk, making it easier to carry in a running vest, belt, pocket, backpack, or hydration pack.

• BITE VALVE HYDRATION: Easy-sip bite valve helps you drink on the go during runs, rides, hikes, and races, so you can hydrate between intervals, trail sections, or workouts without stopping to unscrew a bottle.
• BPA FREE AND REUSABLE: Made for repeated active use with BPA-free materials, this reusable hydration flask is a practical choice for runners, cyclists, hikers, travelers, and outdoor gear bags.
• LIGHTWEIGHT PACKABLE DESIGN: Folding water bottle packs down small when empty, saving space in running belts, hiking packs, bike bags, luggage, and race-day kits while staying easy to carry and store.
• IDEAL 150ML COMPACT SIZE: Small 5 oz capacity is best for short to medium sessions, quick sips, gels, or supplemental hydration, helping avoid extra weight when you do not need a larger 250ml or 500ml flask.
