What Clothes to Wear for Summer Hiking

A summer hike can quickly become uncomfortable when overheating, sudden rain, and damp clothing start slowing you down on the trail.

This situation is especially relatable in the UK, where summers are highly unpredictable.

Your kit has to handle it all without slowing you down. This guide walks through exactly what to wear on your summer hikes, layer by layer, with practical tips for handling the British weather.

What to Wear on a Hike: Quick Summer Checklist

Most British summer hikes call for the same core kit, with small tweaks based on the route. This kit includes:

• A breathable technical t-shirt or UPF sun shirt
• Lightweight walking trousers, shorts, or convertibles
• A packable waterproof jacket
• Cushioned merino or synthetic hiking socks
• Hiking shoes, boots, or trail runners suited to the trail
• A wide-brim hat or cap, plus UV-rated sunglasses
• A comfortable backpack loaded with water, snacks, and sun cream

What Clothes to Wear for Hiking in Hot Weather (A Detailed Breakdown)

With the essentials covered, let’s break down each part of a practical summer hiking kit and what actually matters when choosing clothing for warm-weather walks. 

Start with a Breathable Base Layer

Your base layer sits directly against your skin, so it needs to handle sweat well and dry quickly. A breathable shirt helps keep you cooler and more comfortable during long walks and steep climbs 

A few options worth considering are the following:

• Lightweight t-shirts for easy walks and warm coastal paths
• Long-sleeve sun shirts for bright days when you want to avoid reapplying sun cream every hour
• UPF-rated shirts, ideally UPF 30 or higher, provide additional protection during high-UV conditions. 
• Tank tops for serious heat, though they won't protect your shoulders from the sun or your arms from sharp brambles. 

Choose Lightweight Walking Trousers or Shorts

Your choice between trousers and shorts depends entirely on the terrain and the bug situation. Lightweight ripstop or quick-dry nylon trousers protect your legs from ticks, brambles, and sunburn, while still breathing well enough on warm days.

Zip-off convertible trousers are especially useful for UK hikes because they easily adapt to changing weather conditions. 

Shorts work well for hot, lowland walks on maintained paths. However, they become less practical on overgrown trails or insect-heavy routes where exposed legs are more vulnerable to scratches and bites.

Pack a Lightweight Waterproof Jacket

British summer rain is unpredictable, so a waterproof jacket needs to be in your backpack every single time you head out. A packable shell under 400 grams folds away small and can be pulled out quickly the moment the sky turns grey.

When you are choosing one, look for:

• Taped seams
• A properly shaped hood
• A hydrostatic head rating of at least 5,000mm if you frequently walk through showers.

On drier days, a lightweight softshell is a great alternative because it blocks the wind on exposed ridges and keeps you from overheating.

Use Comfortable Hiking Socks

Cotton sports socks can quickly become uncomfortable because they trap moisture and increase friction during long walks. Merino wool socks are best for summer hiking, as they regulate temperature and keep their cushioning over long days. 

Before wearing new hiking socks on a full-day walk, test them on a shorter hike first to make sure they feel comfortable and do not cause friction. 

What Are the Best Fabrics for Clothes for Summer Hiking

Fabric choice is one of the most important factors in staying comfortable during summer hikes, so it is worth getting right before you spend your hard-earned money. 

Here is a quick reference guide to show you which fabrics work best for different pieces of kit:

Fabrics to Avoid for Summer Hiking

Some fabrics earn their place in everyday wear but fall apart on the trail. Here is what you should avoid packing:

• Cotton: Absorbs and holds sweat instead of drying quickly, which can leave you feeling cold, damp, and prone to chafing. 
• Heavy denim: Restricts movement and takes longer to dry.
• Thick fleece: Traps too much midday heat and adds weight.
• Tight gym leggings: Tear easily on brambles and offer zero protection.

What Footwear Should You Wear on a Summer Hike?

Footwear depends entirely on the trail. The wrong choice will end your day early, no matter how excellent the rest of your kit is.

Three main options that cover most UK summer hikes include:

Hiking Shoes

Low-cut shoes are perfect for well-marked footpaths and gentle hills because they are much lighter and cooler than traditional boots. 

Look for a pair with a tough, reinforced toe and a grippy rubber outsole for security on the trail.

Hiking Boots

Boots earn their keep on boggy ground, rocky terrain, and routes where you are carrying a heavy pack. They support your ankles on uneven steps and protect your feet from deep puddles.

Trail Running Shoes

Trail running shoes are lightweight, dry quickly, and allow more natural foot movement on smoother trails.

However, you should skip them if you are carrying a heavy pack or walking through rocky areas where you need ankle support.

Essential Accessories for Summer Hiking

Accessories help protect the areas your main gear may not fully cover. Sun protection, eye protection, and proper storage all matter once you are a few hours into a walk. The most important must-have accessories include:

Hats and Caps

A wide-brim hat shields your face, ears, and neck from the sun, while a standard baseball cap works great for shaded trails and cooler weather. 

For breezy ridges, a hat with a chin cord saves you from chasing it down a hillside.

Sunglasses

Polarised lenses reduce glare from wet ground and water, helping minimise eye strain on bright days. Choose UV400-rated sunglasses with a wraparound design for better protection on exposed trails where sunlight can hit from multiple angles. 

Lightweight Backpacks

A 15 to 25 litre daypack carries everything you need for a full day, such as:

• Water
• Snacks
• Packable jacket
• Sun cream
• Plasters

Look for ventilated back panels and a hip belt on these bags for longer hikes.

Simple Ways to Stay Comfortable on Long Summer Walks

A few small habits will make a bigger difference than expensive gear, such as the following:

• Freeze your water bottles halfway through the night before and top them up with cold water in the morning to enjoy ice-cold drinks all day.
• Keep your waterproof jacket at the top of your pack, not buried at the bottom
• Pack a spare pair of fresh socks in your bag to swap into halfway through a long, hot walk.
• Keep your phone or camera inside a backpack pocket or covered compartment, as direct summer sun can cause the battery to overheat and shut down. 
• Eat small snacks every hour or so to stay fresh, even if you do not feel hungry.
• Apply SPF lip balm alongside your sun cream, since lips burn fast on bright days.
• Dip your hat or a bandana in a cold stream along the trail to get an instant, refreshing cool-down.

Conclusion

Summer hiking in the UK rewards good planning more than fancy labels. Stick to breathable base layers, lightweight trousers, a packable waterproof, and trail-appropriate footwear, and you will handle everything from a Pembrokeshire cliff path to a Cairngorm ridge. 

Match your kit to the day's weather, terrain, and your pace, and you will spend less time fiddling with zips and more time enjoying the view.

FAQs

What is the best walking men's clothing for summer hikes?

A breathable technical t-shirt or a lightweight UPF long-sleeve sun shirt paired with quick-drying walking trousers will cover most British summer hikes. Complete the outfit with a packable waterproof jacket, merino wool socks, and proper hiking shoes or trail runners.

What colours are best for summer hiking clothes?

You should choose light and neutral shades like beige, sage, light grey, and stone, as they reflect sunlight and feel cooler in the heat. Do not go for darker colours as they absorb heat and tend to attract more insects in some conditions.

Can you wear everyday gym clothes for hiking?

A gym kit is perfectly fine for short, easy walks on dry paths. However, on longer hikes or rougher terrain, it quickly proves inadequate in terms of durability and protection from the elements. Go for proper walking trousers that handle brushed rocks and sudden showers in a way running tights simply cannot.
