Upgrade Your Hydration Routine with a Space-Saving, Eco-Friendly Design

The NEWBOLER 250ml 500ml Water Bottle TPU Folding Soft Flask is more than just a water container—it’s a game-changer for active lifestyles. Whether you’re a trail runner, camper, hiker, or daily commuter, this collapsible water bottle eliminates bulk while keeping you hydrated. Made from high-grade TPU (Thermoplastic Polyurethane) , it’s lightweight, leak-proof, and folds down to fit in your pocket when empty. Say goodbye to rigid, heavy bottles and hello to portable convenience.

Available in two practical sizes—250ml for short runs or kids’ packs, and 500ml for longer adventures—this soft flask adapts to your needs. It’s the ultimate upgrade for anyone seeking a reusable, BPA-free alternative to single-use plastic bottles.

Key Features & Benefits of the NEWBOLER Folding Water Bottle

Premium TPU Material – Safe, Durable, and Flexible

Unlike cheap plastic or silicone, TPU offers superior puncture resistance and temperature stability. The NEWBOLER water bag withstands freezing and mild heat (do not boil), making it ideal for year-round use. It’s 100% BPA-free, odorless, and food-grade safe—perfect for water, electrolyte drinks, or protein shakes during workouts.

Collapsible & Ultra-Portable – Fits Anywhere

When empty, this folding soft flask rolls or folds into a palm-sized bundle. The 500ml version compresses to less than 1/4 of its full size, sliding easily into a running vest, hiking backpack, or even a jeans pocket. No more juggling rigid bottles or searching for water fountains—carry hydration without the weight penalty.

High-Flow Bite Valve & Leak-Proof Cap

The sports drinking nozzle features a hands-free bite valve. Simply bite and sip; the valve seals automatically when you stop. Great for running, cycling, or climbing where you need quick access without stopping. The screw-top lid ensures zero leaks during transport—toss it in your bag with confidence.

Two Sizes for Different Activities

• 250ml Model – Ideal for kids’ hydration packs, 5K runs, or as a backup flask. Ultra-light at just 30g.

• 500ml Model – Best for half-marathons, full-day hikes, or camping trips. Balances capacity and compactness.

How to Use & Care for Your NEWBOLER Soft Flask

1. First use – Rinse with warm soapy water. Air dry completely before folding.

2. Filling – Do not exceed the max fill line. Leave a small air gap to prevent valve pressure.

3. During activity – Use the bite valve for one-handed drinking. Squeeze gently if you need a faster flow.

4. After use – Empty, rinse, and leave open to dry. Store flat or rolled.

5. Deep cleaning – Use a bottle brush or a drop of mild bleach in water. Rinse thoroughly. Do not microwave or boil.

Pro tip: Freeze the flask half-filled for cold water on long hikes. The TPU material expands slightly—leave room for ice expansion.
