Collapsible Soft Running Water Bottle – Lightweight TPU Flask with Pull-Open Valve, 250ml/500ml for Trail Running, Hiking & Cycling
FOR RUNNERS WHO KEEP MOVING
Your Run Should Flow. Your Water Bottle Should Too.
You're finding your rhythm, picking up the pace, and enjoying every mile. The last thing you need is a bulky water bottle bouncing against your chest or interrupting your stride.
Traditional hard bottles can rattle, shift around, and take up the same amount of space even after you've finished every drop. And when you're pushing through a challenging run, stopping just to drink water can break your momentum.
MEET YOUR NEW RUNNING ESSENTIAL
Meet the Collapsible Running Flask.
Hydration designed to move with you — not against you.
The 500ml Soft Flask replaces the bulk of a traditional water bottle with a flexible, lightweight design made for active movement. Its soft body compresses as you drink, helping reduce water sloshing while fitting comfortably into compatible running vest pockets.
With its convenient squeeze-to-drink design and compact fold-down construction, you can stay hydrated on the move and carry less bulk as your adventure continues.
💧 Less Sloshing
Soft body shrinks as water is consumed.
🏃 Runner-Friendly Fit
Flexible shape contours to your running vest.
🤏 Easy Squeeze
Convenient hydration while staying active.
🎒 Packs Down Small
Roll or fold it when empty to save space.
01 / EFFORTLESS HYDRATION
Keep Your Pace. Take a Sip.
One-hand squeeze. Easy hydration. No unnecessary interruptions.
When you're in your running zone, every movement should feel natural. The Soft Flask is designed for convenient, on-the-go drinking, making it easier to refresh yourself during a run without dealing with a bulky traditional bottle.
Hydration that keeps up with your adventure.
02 / THE SOFT FLASK ADVANTAGE
Less Water. Less Sloshing.
A bottle that gets smaller with every sip.
Unlike a rigid bottle that keeps its shape as water disappears, the soft flask gradually compresses as you drink. This helps minimize the air space inside the bottle, reducing distracting water movement during your run.
The result? A quieter, more comfortable hydration experience that lets you focus on your breathing, your pace, and the trail ahead.
03 / MADE FOR MOVEMENT
A Better Fit. A Smoother Run.
Flexible comfort for the miles ahead.
Your running vest should feel like part of your gear, not something you're constantly adjusting.
The Soft Flask features a flexible, contoured body that slides into compatible hydration vest pockets and adapts more naturally to your body than a rigid bottle.
🏃 Less Bounce
Soft construction helps minimize uncomfortable movement.
🎽 Vest-Friendly
Designed to fit compatible front hydration pockets.
☁️ Flexible Comfort
Soft bottle walls adapt to your movements.
⚡ Quick Access
Keep your water conveniently within reach.
Designed for comfort and compatibility with running hydration gear.
04 / COMPACT BY DESIGN
Full When Needed. Small When Empty.
Carry your water — not unnecessary bulk.
A traditional water bottle takes up the same space whether it's full or empty. The Soft Flask is different.
Once you've finished your water, its flexible body can be folded or rolled into a compact shape, freeing up valuable room in your running vest, backpack, or travel bag.

05 / THE RUNNER'S DIFFERENCE
Feel the Difference With Every Stride.
Not every water bottle is built for running.
Hard plastic bottles may work well for everyday use, but their rigid shape can become uncomfortable when placed against your chest during repetitive movement.
The soft, collapsible design provides a more movement-friendly alternative for active runners.

FREQUENTLY ASKED QUESTIONS
Questions? We've Got Answers.
Here's what we'd like you to know before taking your soft flask on your next adventure.
1. Will this soft flask fit my running vest?
We've designed the soft flask with a flexible, contoured body that works well with many running vest hydration pockets. Because pocket sizes vary between brands and models, we recommend checking your vest's pocket dimensions before purchasing. Its soft construction also makes it easier to position than many rigid bottles.
2. Does the bottle really shrink as I drink?
Yes! That's one of the main advantages of our soft flask design. As you drink, the flexible bottle compresses rather than maintaining a rigid shape. This helps reduce the space available for water to slosh around. When the flask is empty, you can fold or roll it down for easier storage.
3. How do I drink from the flask while running?
We've designed our flask for convenient squeeze-to-drink hydration. Simply access the drinking nozzle and gently squeeze the flexible bottle to help control the flow of water. We recommend trying the nozzle and familiarizing yourself with the flask before your first run so you can use it comfortably while moving.
4. How do I clean and maintain the soft flask?
We recommend rinsing your flask thoroughly before its first use. For everyday care, wash the bottle and cap with lukewarm water and mild dish soap, rinse completely, and allow all components to air-dry before storage. Avoid abrasive cleaners and extreme heat. We also recommend keeping the flask clean and dry between uses.
5. Is this flask suitable for hiking and everyday workouts?
Absolutely! While we've designed this flask with runners in mind, its flexible, portable construction also makes it a convenient option for hiking, outdoor workouts, and active travel. With approximately 500ml of capacity, it's a practical way to carry water without relying on a bulky hard bottle. For longer activities, we recommend planning your hydration needs and carrying additional water when necessary.
