What to Wear Hiking in Hot Weather (Without Overheating)

Summer hiking is a rewarding way to explore the outdoors, but hiking in hot weather comes with its own set of challenges. Overheating, dehydration, and sunburn can quickly turn a scenic trek into a miserable ordeal if you aren’t properly prepared. That’s why knowing what to wear hiking in heat is just as important as choosing the right trail.

In this guide, we’ll cover essential summer hiking clothes, gear recommendations, and hot weather hiking tips to help you stay cool, safe, and comfortable when the temperature climbs.

1. Choose Lightweight, Breathable Fabrics

The first rule of dressing for hot weather hiking is to avoid heavy or cotton fabrics. Cotton tends to trap moisture and dries slowly, increasing the risk of chafing and overheating. Instead, look for these materials:

• Nylon
• Polyester
• Merino wool (for odour resistance and moisture-wicking)

These synthetic or performance fabrics are designed to wick sweat away from your body, dry quickly, and allow for better airflow.

Pro Tip:

Look for UPF-rated fabrics to get built-in sun protection.

2. Go with Light-Coloured Clothing

Light colours reflect sunlight, while dark colours absorb it. Wearing light-coloured clothing can significantly reduce how much heat your clothes retain.

• Opt for shades like white, beige, light grey, or pastels.
• Avoid black or navy during peak sun hours.

Hot Weather Hiking Tip:

Some light-coloured clothing is treated with UV-blocking agents. Check the label for a UPF rating of 30 or higher.

3. Pick the Right Hiking Shirt

When selecting a hiking shirt for hot weather, think about ventilation, fit, and protection:

• Short-sleeved or long-sleeved? Long sleeves offer more sun protection, but make sure they’re breathable.
• Mesh panels and zippered vents can improve airflow.
• Look for shirts labelled “sun shirts” or “cooling shirts.”

Avoid cotton T-shirts—they soak up sweat and turn into heavy, clingy messes.

4. Wear Moisture-Wicking Hiking Shorts or Pants

Your lower half matters too! For most summer hikes, moisture-wicking hiking shorts are ideal. But if you’re hiking through brush, bugs, or sun-exposed areas, consider lightweight hiking pants with built-in ventilation.

• Convertible pants (that zip off into shorts) offer versatility.
• Avoid jeans or heavy canvas materials.
• Prioritize comfort, stretch, and breathability.

Bonus Tip:

Pants with side vents or mesh-lined pockets can offer surprising relief on hot days.

5. Protect Your Feet: Breathable Hiking Socks and Ventilated Boots

Your feet take the brunt of any hike, and overheating can lead to blisters. To prevent discomfort:

• Wear lightweight, moisture-wicking hiking socks (avoid cotton!).
• Choose ventilated trail shoes or breathable hiking boots.
• In extremely hot, dry climates, hiking sandals with good grip can work for well-maintained trails.

Don’t forget to break in any new footwear before attempting a long hike.

6. Use a Wide-Brimmed Hat or Cap

Sun exposure to your head and neck can increase body temperature rapidly. A proper hiking hat can prevent sunburn, heatstroke, and glare:

• Wide-brimmed hats offer full coverage.
• Caps with neck flaps protect your neck from UV rays.
• Look for mesh vents for breathability.

Some hats come with sweatbands or cooling fabrics to help regulate temperature.

7. Don’t Skip the Sunglasses

Protect your eyes with UV-blocking sunglasses. Bright sunlight reflecting off rocks, sand, or water can strain your eyes and increase fatigue.

Polarized lenses are best for cutting glare and enhancing trail visibility.

8. Apply Sunscreen—And Reapply Often

Even with UPF-rated clothing, exposed skin needs protection. Use a broad-spectrum sunscreen with SPF 30 or higher, and don’t forget these spots:

• Ears
• Neck
• Hands
• Back of your knees (if wearing shorts)

Reapply every 2 hours or more frequently if sweating heavily.

9. Stay Hydrated with a Lightweight Pack and Hydration System

While not technically clothing, carrying a hydration-compatible backpack helps ensure you stay cool and safe. Look for:

• Hydration bladders with drink tubes for easy access
• Lightweight packs with ventilated back panels
• Mesh shoulder straps for breathability

Consider adding electrolyte tablets or drinks to replace what you sweat out.

10. Cooling Accessories Can Make a Big Difference

If the heat is intense, consider accessories designed specifically to keep you cool:

• Cooling towels you can wet and drape around your neck
• UV sleeves that wick moisture and protect your arms
• Cooling bandanas or gaiters

Some of these can be reactivated with just a splash of water.

Final Thoughts: Dress Smart, Hike Smarter

Knowing what to wear hiking in hot weather can transform your summer hikes from sweaty slogs to enjoyable adventures. Focus on breathable, lightweight clothing in light colors, invest in sun-protective gear, and don’t underestimate the value of proper hydration and cooling accessories.
