In trail running, the pack is not just an accessory. It becomes a strategic ally over long distances, especially in the mountains or on an ultra. Comfort, stability, capacity, accessibility… here are the essential criteria for choosing the right trail running pack.

1. Capacity: according to the distance and the gear

A 3 to 5L pack is enough for short distances or half-day runs. As soon as you move up to long formats (marathon, ultra), go for a volume of 8 to 12L so you can carry nutrition, mandatory gear and a change of clothing.

2. Carrying comfort

The pack has to follow your body shape like a second skin. Look for an ergonomic, light and breathable structure. The shoulder straps should be wide, with no harsh seams. The Ultrun EVO 10 is a benchmark for long-distance comfort.

3. Stability on the move

A pack that bounces tires you out and chafes. Choose a model with multiple adjustment points (sternum and side straps) to avoid unwanted movement, even on descents or technical terrain.

4. Pocket accessibility

You need to be able to grab a flask, a bar or a jacket without taking the pack off. Go for well-positioned zipped front and side pockets. The COMPRESSPORT model is designed for optimised access, even mid-race.

5. Compatibility with your gear

Check that the pack can take your flask, your survival blanket, your poles or your windbreaker. Some models include a system for holding poles without getting in the way. Round it all off with a belt if you need extra versatility.

6. The intended use: training, racing or ultra

In training, a small pack or a belt can be enough. For a long race or an ultra with mandatory gear, go for a pack that is robust, stable and tested in real conditions.

Pair your pack with a coherent kit

To get the most out of your pack, pair it with suitable shorts, a breathable T-shirt, technical socks and a lightweight cap. Everything comes down to your trail running kit as a whole.

Conclusion: test it before you set off

A good trail running pack should be discreet, functional and stable. Test it loaded before your race, on similar terrain, and fine-tune your adjustments. To go further, read our complete guide: the key points for choosing the right trail running pack.
