Hydra Flask 500ml - Marathon des Châteaux du Médoc 2026 - Limited Edition

Running flask: water that follows the hand

A running flask can be held in the hand or slipped into a belt. Hydra Flask Bodycross flasks are flexible: their shape adapts to the hand during exercise, and they remain compact. They are made of thermoplastic polyurethane (TPU), free from BPA, PVC, and PFCs, for safe even prolonged use. They have a gradient finish and are suitable for both training and competition.

250 ml or 500 ml: choosing the volume



  • Hydra Flask 250ml: the most compact. It fits in the front pocket of the Power Hydration Belt 250ml and in shorts with a 250 ml flask pocket.


  • Hydra Flask 500ml: for long runs. The Power Hydration Belt 500ml accommodates it in its front pocket.

You can also combine the two: 500 ml in front and 250 ml in the back, in the 500 ml belt. You thus carry 750 ml without a backpack.

Trail cup: drinking at aid stations

The Hydra Cup 150ml is a flexible and compact cup. It fits in the hand and can be stored in a belt or running vest. It is also made of TPU without BPA, PVC, or PFCs. Some races no longer provide disposable cups at aid stations: read the rules of your event to find out if a personal cup is required.

Where to store your flask

To carry one or two flasks without a backpack, see our hydration belts. Some shorts have a dedicated pocket: compare them in the men's shorts and tights and the women's shorts and tights. The rest of the equipment is in the trail equipment.

250 ml or 500 ml running flask: which one to choose?

Can you fit a soft flask in running shorts?

Yes, if the shorts have a pocket designed for it. Some Bodycross 2-in-1 shorts have a pocket for a 250 ml flask: the Hydra Flask 250ml fits perfectly. The 500 ml is too bulky for this type of pocket; it is better carried in a belt. Compare the models in our men's shorts and cycling shorts.
