Warm jackets: smart insulation on the trail

Cold conditions call for more than just walking. With the right jacket, you prevent cooling down and conserve energy—essential for both comfort and performance.

Down jacket (maximum warmth, minimum weight)

Are you unsure when using down? Down jackets are ideal for breaks, summits, and extremely cold conditions. They offer plenty of warmth in a compact size and are easy to carry in your backpack.

Softshell (active heat while running)

For movement, you often choose a softshell. It is breathable, lightly insulating, and protects against wind. Perfect for cold, dry runs where you want to stay warm without sweating.

When do you choose what? (practical decision aid)

• Down jacket → standstill, moments of rest, extreme cold
• Softshell → active walking, cool to cold conditions
  Many trail runners combine both for maximum flexibility.

Lightweight & packable (always prepared)

Both down jackets and softshells are designed to be carried without ballast. Compact to store and quick to put on when the temperature drops.

Frequently Asked Questions

Can I wear a down jacket while walking?
Only at very low intensity or extreme cold. Usually, a softshell is more comfortable during movement.

Is a softshell waterproof?
No, usually water-repellent. For real rain, you need a rain jacket.

Do I need both?
Not always, but together they offer maximum flexibility in cold conditions.

Smart combination

• Combine with a layering system (shirt + midlayer) for optimal temperature regulation
• Take a rain jacket take along in case of chance of precipitation

Stay warm without compromising on comfort. Choose the right insulation and face every cold trail prepared.
