WRELS Collapsible Soft Flask – BPA-Free Sport Water Bottle

The WRELS Collapsible Soft Flask is molded from food-grade, antibacterial TPU and folds flat for compact storage between refills on the trail or at the gym.

Capacities: 300ml, 500ml. Colors: blue, red.

• Reduces pack weight with a lightweight foldable design
• Supports running, hiking, camping, and marathon training
• Includes a silicone bite nozzle for quick drinking access

Also suited for walking, travel, and everyday outdoor hydration where a compact bottle is preferred. The flask folds down small enough to store in a jersey pocket when empty. Many runners keep a spare flask clipped to a race belt for backup hydration.
