Hiking in summer temperatures? Here's how to keep your cool

When the sun is out and the temperatures soar, heading into nature feels like the perfect escape. But if you're hiking in 25°C and above, you'll quickly learn that the wrong gear can turn even the most scenic trail into a sweaty challenge. The good news? With the right clothing, you don’t have to sacrifice comfort or protection.

Light, airy, and protective – What your summer hiking gear should offer

In summer, freedom of movement and comfort are key – whether you're powering through a steep mountain hike or enjoying a laid-back stroll through nature. That’s where smart hiking wear makes all the difference. Breathable fabrics that wick away moisture help keep you dry and comfortable, even when the trail gets steep and your pace picks up.

Even better: some fabrics feature a cooling effect to help you stay fresh – especially when the temperature climbs above 25°C.

Flexibility matters, too. That’s why your gear should move with you – offering stretch and support no matter the terrain. Whether you're scrambling over rocks, pacing through forests, or lounging after a long hike, stretchy fabrics ensure freedom of movement without restriction.

And don’t forget about the weather. Sudden summer storms or gusty winds can catch you off guard. Luckily, modern performance fabrics protect against wind and light rain without causing overheating.

Then there's sun protection – an absolute must in the mountains or anywhere without shade. Clothing with built-in UV filters lets you stay out longer without constantly reapplying sunscreen. That means more freedom, more safety, and more enjoyment on your summer adventures.
