Hydration pack and vest FAQ
What vest or pack volume do I need for trail running?
As a guide: 3–5 L up to about 30 km, 5–10 L for mountain marathons and 50 km, and 10–15 L for long ultras or heavy mandatory gear lists. Check your race’s mandatory gear list first.
Soft flasks or a hydration bladder?
Flasks sit on the chest, refill fast and show how much is left. A bladder carries more water (1.5–2.5 L) on your back and pays off on long stretches without aid stations. Many vests take both.
How do I pick the size?
By the chest circumference the brand lists. The vest should feel firm without restricting breathing and without bouncing: always try it with water in.
What does “litres per 100 g” mean?
It is volume divided by weight, showing how much space each gram gives you. Higher means more weight-efficient, but it says nothing about comfort or fit.
Why do some models show no radar?
The brand does not publish a key figure (for example empty weight) and we do not invent one. They still appear in the table with their verified data.
Does the weight include the flasks or bladder?
No: we compare the empty vest as the brand states it. With water, real weight rises by roughly 1 kg per litre.
Women’s or unisex vest?
Some models have a pattern designed for a female chest. What matters is the size by chest circumference and that nothing rubs or squeezes once the water is in.
How much water should I carry?
Roughly 400–800 ml per hour depending on heat and effort. Match the capacity to the distance between aid stations and to your race rules.
