The trail runner vest
The hydration pack for trail running is more like a vest than a backpack: it fits snugly around the torso, so it doesn't bounce, even downhill. It carries water at the front, in soft flasks tucked into the chest pockets, which are accessible without stopping, while the back holds the gear: waterproof jacket, warm layer, food, emergency blanket. Multiple chest straps allow for precise adjustments.
Other bags
Trail luggage also comes in various forms:
All the luggage can be found on the luggage page.
The volume based on the race
The volume, in litres, is chosen based on the duration of outings. A belt, like those from Asics, Nike or Coxa Carry, is enough for an hour or two. A vest of five to eight litres, like the Dynafit Alpine, the Silva Strive Fly, or the Patagonia Slope Runner, is suitable for long outings and short trails. A vest of ten to twelve litres, like the Osprey Duro Pro or the Oxsitis Spectre, accommodates the mandatory gear for ultra-trails. It's better to have a slightly larger vest than one that's too stuffed, which compresses the torso.
The women's versions
Women’s vests, like the Osprey Dyna Pro or the Oxsitis Spectre W, from the French trail brand, are tailored for the chest: the flasks are positioned higher or on the sides, and the straps prevent compression. You pick your size based on your chest circumference, trying it on loaded. Flasks should be washed with warm water after each use and left to dry open, to avoid bad smells. The Fitletic Hydra, simpler, accompanies training outings.

Frequently asked questions
What volume of hydration pack should I choose for trail running?
About five litres is enough for outings of a few hours and short trails. For ultras, with mandatory gear, aim for ten to twelve litres, enough for the jacket, warm layer, and food.
How to choose the size of a hydration vest?
Measure your chest circumference and refer to the manufacturer's guide. The vest should fit snugly without restricting breathing; the chest straps allow fine adjustment, even when loaded.
Flasks or hydration bladder: what to choose?
Soft flasks at the front fill quickly at aid stations and allow you to monitor what you're drinking. The hydration bladder in the back carries more volume, useful on long outings without a water source.
Why choose a women's hydration pack?
The women's models, like the Osprey Dyna Pro or the Oxsitis Spectre, have straps and front pockets positioned to avoid compressing the chest. Their shorter torso provides better stability while running.
Belt or hydration pack for running?
The belt, like those from Asics or Nike, is sufficient for a one- or two-hour outing with a flask and a phone. Beyond that, or in the mountains, the vest carries enough water and gear without bouncing.
