What to Wear for Light and Technical Trekking
More performance, more comfort, less weight: Here’s how to dress smart for light and technical alpine hikes.
Whether you’re heading out on a fast-paced day hike or planning a multi-day trek with overnight stays, choosing the right hiking clothes is essential for your safety, comfort, and overall experience. In this guide, we’ll show you how to build a high-performance lightweight layering system tailored for hiking in alpine environments.
The Foundation: The Layering System
In alpine terrain, weather can change rapidly. That’s why your hiking outfit should be made up of multiple layers that are easy to add or remove depending on your activity level and the elements.
1. Base Layer – Manage Moisture and Temperature
Every good hiking clothing system starts with a quality base layer. A base layer made from pure merino wool offers excellent thermal regulation and stays fresh for longer, even after extended use. It wicks moisture away from your skin, helping you stay dry and warm.
Pro tip: Avoid cotton. It absorbs moisture and cools your body down when wet.

2. Mid Layer – Insulate Your Body Heat
The mid layer’s main job is to retain body warmth and provide insulation in all weather conditions. For fast-paced or technical hiking, a synthetic mid layer is ideal—it offers lightweight insulation, breathability, and reliable performance even in damp conditions.
Pro tip: If you’ll be hiking at high altitudes where temperatures drop at night, consider adding an insulated vest or a lightweight puffer jacket.

3. Outer Layer: For Most Weather
When you’re on the move for hours at a time, your outerwear should protect you from wind and light moisture without trapping excess heat or sweat. A lightweight, durable, and stretchy softshell jacket with high breathability is often the best choice—at least when the rain holds off.
Pro tip: Many softshell jackets for hiking also work great for ski touring and alpine missions in winter.
