Flat soft flasks for your running belt

Do you want to carry a drink without wearing a trail vest? A flat soft flask fits better in many running belts and waistbands than a tall, narrow soft flask. The flat shape distributes the volume over a larger surface area, causing the flask to protrude less and lie more comfortably against your body.

That makes this type of soft flask ideal for short and medium-length training sessions, races, or warm runs where you need just a little extra to drink.

Why a flat soft flask in your running belt?

A standard soft flask is often designed for the vertical chest pockets of a trail vest. If you place such a model in a waist belt, it can stick out, shift, or press uncomfortably against your back or stomach.

A flat soft flask is specifically designed to be carried horizontally. This allows you to utilize the space in your running belt more efficiently and keeps the weight closer to your body. Less bumping and less bulk simply means a more comfortable run.

Which size fits your running belt?

Always check how much space your running belt offers and which flask sizes are recommended for it. A larger capacity allows you to carry more drink, but it must fit fully and securely in the pocket.

For shorter runs, a compact, flat soft flask may suffice. If you are going out for longer or running in warm weather, a larger capacity can be pleasant. Be sure to choose a size that fits well on your belt so that the flask does not move unnecessarily while running.

Flat soft flask or standard soft flask?

Do you wear a trail vest with soft flasks on the chest? Then a standard soft flask usually the most logical choice. Would you rather walk with a running belt or waistband, then a flat soft flask often provides a much better fit.

If you want to keep your drink cool for longer, check out the insulated soft flasks. For easier drinking from a trail vest, there are softflasks with straws handy, while a soft flask with filter is suitable when you want to use water from natural sources while on the go.

Choose a flat soft flask if you want to walk light and freely without a jacket, but still want quick access to your drink along the way.
