Summer in Hemsedal means long days, fresh mountain air and endless opportunities to explore. But the mountains play by their own rules. Sunshine can quickly turn into cool winds and changing weather – sometimes all in the same day. That’s why one thing always matters: what you wear.

With the right clothing, your mountain experience becomes more comfortable, safer and far more enjoyable. Whether you’re heading out for a short walk, a full-day hike or just plan to be outdoors from morning to evening.

Layering – even in summer
Layering isn’t just for winter. In the mountains, it’s useful all year round. It allows you to adjust easily to temperature changes, wind and activity level – without having to turn back.

What to wear in summer

Lightweight, breathable jacket or mid-layer
Even warm summer days can feel cool in the evening or when the wind picks up. A thin jacket or light fleece doesn’t take up much space and is worth its weight.

T-shirt or shirt in technical fabric
Choose breathable, quick-drying materials for all-day comfort – especially when you’re on the move.

Shorts or lightweight hiking trousers
Freedom of movement is key. Shorts are great on warm days, while light trousers offer extra protection at higher altitudes.

Cap or sun hat
The sun can be strong in the mountains. A little shade goes a long way.

Sunglasses
Bright light and reflections from water and rock can be surprisingly intense.

Footwear with good support
Sturdy hiking shoes or lightweight mountain boots provide stability on varied terrain.

Swimwear
Yes, really. Mountain lakes, rivers and pools are often too tempting to resist on warm days.



What to pack in your backpack

Even on short hikes, your backpack is a small safety net. Weather can change, and trips often take longer than planned. You don’t need much – just the essentials.

An extra layer
A lightweight jacket, windproof layer or thin jumper can make a big difference when temperatures drop.

Food and water
Bring more than you think you’ll need. Fresh mountain air builds an appetite, and staying hydrated is essential on warm days.

Map or mobile with offline maps
Mobile coverage isn’t guaranteed everywhere. A bit of preparation adds a lot of peace of mind.

Sun protection
Sunscreen and sunglasses. The sun is strong at altitude, even when there’s a breeze.

Small first aid kit
Blister plasters, tape and a few basics can save the day.

Sit mat
For breaks with a view – and a bit of extra comfort.

Swimwear and a small towel
Just in case you pass a mountain lake you can’t say no to.

Comfort, safety and respect

Dressing properly in the mountains isn’t just about comfort or style. It’s about safety – and respect for nature. When you choose the right clothing and pack smart, you give yourself the freedom to explore the mountains in a safer, more relaxed way.
