Description

Drink more for long stretches on the road. This large soft flask is intended for trail runs and ultras where you run for extended periods without a water station or aid station.

Flexible despite the larger capacity. The slim shape slides more easily into a suitable hydration compartment, and the flask shrinks as you drink. You notice the advantage especially later in a long ultra, when you don't have to refill as often.

Choose this one if reach is more important than compactness. The wide opening helps with quick filling of water, sports drink, or ice, while the lockable drinking spout limits leakage during transport.

For short runs or small jacket pockets, a more compact soft flask is more practical.

Why Ultraspire?

On a long trail run you only notice how well your gear fits when it doesn't: a bottle that bounces, a belt that creeps up, or a light that gives you just too little light. That is exactly why we carry Ultraspire at trrail.com.

Ultraspire makes hydration and gear for runners: soft flasks with matching caps and straws, handhelds, running belts, trail vests and waist lights. The parts fit together, so you can expand your setup instead of starting over. Handy for long runs, ultras and training in the dark.

For us, Ultraspire is above all a practical brand: gear that does what it should, without fuss, and that you can easily combine into a setup that suits your distance.

Fijne softflask met grote opening (voor bijvullen en toevoegen poeders) en beveiliging n lekken

Fijne softflask met grote opening (voor bijvullen en toevoegen poeders) en beveiliging n lekken. Wel even goed passen want niet per definitie goede fit met elke rugzak.
