Summer Hiking Outfits: What To Wear to Beat the Heat

Summer — a siren song for adventurers of all stripes. Long days promise endless hours of discovery, but the heat can be a formidable foe.

This guide outlines essential gear for optimal performance in high-temperature environments. Whether you're on patrol or exploring off-grid, these clothing tips will ensure you're prepared for the journey ahead.

What are the best materials for summer hiking?

Summer hiking is all about embracing the warmth, soaking up the sun — and staying safe. For those scorching summer trails, you need fabrics that are lightweight, breathable, and dry quickly:

Nylon and Polyester

These synthetic fabrics are the workhorses of summer hiking apparel. They excel at moisture management, rapidly wicking sweat away from the body to keep you dry and comfortable. Nylon and polyester are also lightweight, durable, and quick-drying, making them ideal for unpredictable weather.

ThruDark's pick: Oryon Delta T-Shirt - A highly breathable, half-zip, active t-shirt constructed from innovative Polartec® Delta™cooling fabric. Suitable as a versatile layer for activity in intense heat.

Merino wool

Wool in summer? Absolutely. It might surprise you, but wool is nature's performance fabric and regulates temperature like a pro. Merino wool, in particular, is a revelation. It wicks away moisture, conquers odours, and feels unbelievably soft against your skin. A merino base layer is a luxury you'll wonder how you ever lived without.

ThruDark's pick: Oryon 72hr Merino T-Shirt - A pure merino wool t-shirt, so-called as it has been designed for multi-day expeditions where travelling light is essential.

UPF-Rated Fabrics

Ultraviolet Protection Factor (UPF) gear is clothing that protects your skin from the sun's harmful rays. It's like SPF for your clothes. The higher the UPF number, the better the protection. For those pushing limits in unforgiving landscapes, it’s essential armour.

ThruDark's pick: Oryon Carbon Shirt - A lightweight technical shirt constructed from chrono-carbon, rip-stop fabric for optimum thermal regulation when trekking in arid climates.

Summer hiking outfit essentials

Beat the heat in style. Here's what you need to pack for your next summer hike:

Breathable hiking shirt

Your choice of shirt can determine whether your hike is a pleasure or a pain. Opt for moisture-wicking synthetic materials. These fabrics pull sweat away from your body and dry quickly, helping you stay cool and comfortable.

ThruDark’s pick: Stay cool in intense heat with the highly breathable, half-zip Oryon Delta T-Shirt, made from innovative Polartec® Delta™ cooling fabric. Designed for versatility, it can be worn as a base or sole layer.

Hiking shorts

When it comes to hiking shorts, think flexibility and durability. Lightweight, quick-drying shorts with plenty of pockets are a must. They should provide a full range of motion for those challenging climbs and descents. Bonus points for shorts with built-in UV protection to guard against the sun.

ThruDark’s pick: Command Shorts – light outdoor shorts engineered for extreme pursuits. Ripstop construction protects against tears and abrasions, perfect for rugged trails.

Hiking socks

Never underestimate the power of a good pair of socks. Blisters and discomfort can ruin an otherwise perfect hike. Choose moisture-wicking, cushioned socks designed for hiking. Wool blends are ideal — they keep your feet dry, reduce friction, and provide warmth even when wet.

ThruDark’s pick: Thin, light but with plenty of support whilst on the move, the Tech Socks are the perfect pair for hot weather activity from hiking to trail running.

Headwear

A hat is a must-have for sun protection and overall comfort. Choose a wide-brimmed hat to shield your face, neck, and ears from harmful UV rays. For cooler weather or high-altitude hikes, a warm beanie can help retain body heat. Lightweight, breathable materials ensure your head stays cool and dry.

ThruDark’s pick: Military-inspired, sun-defying, stealthy… Our Watchman Boonie is your ultimate choice.

Extra layer or hiking jacket

Layering is essential for regulating your body temperature and adapting to changing weather conditions. Start with a moisture-wicking base layer to keep sweat off your skin. Add an insulating layer like fleece to retain heat, and finish with a waterproof and windproof outer layer to protect against the elements. The ability to add or remove layers can be a game-changer on unpredictable trails.

ThruDark’s pick: The Oryon Windguard Jacket is packable, windproof, and ultra-light — perfect for summer hikes and expeditions. Stay protected without the bulk.

Hiking Footwear

Your shoes are arguably the most critical piece of gear. Invest in high-quality hiking boots or trail shoes that offer good support, protection, and traction. Consider the terrain you'll be hiking on and choose footwear that matches — ankle support for rocky paths, breathable trail runners for smoother trails. Break them in before your hike to avoid blisters.

Summer hiking wardrobe tips

The mountains aren't interested in your latest tactical gear or designer shades. They care about your grit, your endurance, and your ability to function under pressure. Here are our top tips to optimise your summer hiking wardrobe to beat the heat.

1

Think gear, not glamour:

Gear designed for outdoor activities is built to perform, withstand the elements, and enhance your experience. Forget flashy designs and logos — opt for gear that works.

2

Streamline your kit:

Pack only what you truly need. Every item should have a purpose. This approach not only lightens your load but also reduces the clutter in your rucksack or gear kit.

3

Layer smartly:

Use a layering system suitable for fluctuating summer weather. Start with a moisture-wicking base layer, add a lightweight, breathable mid-layer for insulation, and carry a packable, weather-resistant shell jacket. This system allows you to adapt to sudden changes in temperature and weather conditions.
