In recent years, outdoor sports—especially hiking—have surged in popularity. Accessible to everyone, hiking is great for fitness and lets you explore stunning landscapes with minimal environmental impact. France is a premier hiking destination, packed with waymarked trails across diverse terrains: mountains, countryside, coastal paths, and urban trails. While the trails are free, investing in reliable gear and high-performance clothing is essential. To help you gear up right, Cimalp presents this complete hiking layering guide.
Mastering the Three-Layer System
Every hiker needs a dialed-in layering strategy. The three-layer system guarantees optimal breathability, thermal insulation, and weather protection. By combining technical layers, you can easily adapt your kit as the pace and terrain demand.
The Base Layer
A hiking base layer must above all be breathable. Fabric choices typically range from synthetics (best for high-intensity, shorter efforts) to natural fibres like merino wool (ideal for winter or multi-day trekking). Base layers cover both the upper body (short- or long-sleeved tops depending on the route) and lower body (thermal leggings worn beneath hiking trousers).
The Mid-Layer
This mid-layer provides thermal insulation while transferring body moisture outwards. Fleece jackets are the go-to choice for hiking thanks to their versatility (choose fabric weight based on external temperatures). Alternatively, a down jacket is ideal for cold, dry conditions.
The Outer Layer
As your outer barrier against the elements, this layer must deliver dependable protection. Your third layer adapts to weather conditions, terrain, precipitation, and temperature. Depending on conditions, choose a lightweight windbreaker, a water-repellent jacket, or a fully waterproof rain jacket.
Hiking trousers vary according to terrain and season: zip-off convertible, ultra-lightweight, lined, brushed-fleece, water-repellent, or fully waterproof. If your trousers are not waterproof, pack waterproof overtrousers as a protective outer shell when conditions deteriorate.
Protective Features of Hiking Clothing
Water Repellence vs Waterproofness
Water-resistant hiking apparel falls into two categories: water-repellent or waterproof. A water-repellent fabric causes water droplets to bead up and roll off the surface. It provides initial light-rain protection but will not withstand heavy downpours. The DWR (Durable Water Repellent) treatment must be reproofed periodically to maintain performance.
For uncompromising protection, opt for waterproof apparel built with a technical membrane that seals out moisture. Waterproof performance is rated in Schmerber (water column), making it easy to choose the right rain jacket for your outing. For footwear, select hiking boots engineered with a Gore-Tex® membrane or equivalent to keep water out completely.
There is a wide range of hiking clothing engineered to shield you from the rain. Key options include waterproof jackets and ponchos for the upper body, technical trousers, gaiters, and waterproof overtrousers for the lower body, as well as a rain cover for your hiking backpack.
Windproof Protection
To combat wind chill—which rapidly drains body heat—windproof clothing is essential. Besides preserving core temperature, fully windproof fabrics maintain excellent breathability. Many waterproof and water-repellent jackets integrate wind-blocking tech for comprehensive weather defence.
Properly adjusting your windproof layers is essential to seal out drafts. Tighten your hood, cuffs, and hem drawcord for complete weather protection.
Softshell Gear
Functioning as both a mid-layer and outer layer, softshell apparel delivers multiple benefits: thermal insulation, comfort, water repellence, breathability, wind protection, and unrestricted movement. It has become a staple for hikers thanks to its unmatched versatility. A softshell jacket or trousers will take you almost anywhere—ideal in cold, windy weather, light precipitation, and during high-intensity efforts.
However, we advise against using it when rain is forecast or in unstable mountain weather, especially during multi-day trekking.
Dressing for Every Type of Hiking
Warm-Weather Hiking
Spring and summer offer prime conditions for hiking, allowing you to hit the trails comfortably with minimalist gear. In warm, clear weather, opt for lightweight, highly breathable garments like technical t-shirts, tank tops, shirts, shorts, or light trousers. Always pack backup insulating and protective layers: mountain weather changes rapidly at altitude, and storms can roll in without warning.
Winter Mountain Activities
Winter in the mountains opens up snowshoeing, ski touring, and mountaineering. These demanding disciplines call for warmer, highly technical gear: liner gloves, thermal gloves, gaiters, a balaclava, thermal base layers, fully waterproof jackets, and overtrousers.
Long-Distance Treks
Finally, multi-day routes like the GR20 in Corsica or long treks like the Camino de Santiago demand specific kit. Beyond what you wear on day one, you need spare clothing designed for every condition (insulating, waterproof, breathable, durable) while keeping weight to a strict minimum to lighten your pack. Bottom line: proper layering is vital for hiking. Whether you hike in heat, cold, rain, or howling wind, your clothing must be versatile and dependable, ensuring safety and performance on every trail.
