When going on a hike, it is essential to have the right gear to handle unpredictable weather conditions. A jacket is a key piece of hiking clothing, providing protection against rain, wind, and cold while ensuring good moisture wicking. But with so many models available, how do you choose the right jacket for your needs? From waterproof jackets and water-repellent options to softshells, insulated jackets, and hybrid models, each type serves a specific purpose.
In this comprehensive guide, we will explore the essential criteria to consider, the various technologies used, and how to choose the right jacket based on weather conditions and the type of hiking you plan to do.
Finding the Best Outdoor Jacket for Hiking or Trekking
The choice of a hiking jacket primarily depends on the conditions you will be facing. A simple summer hike on open trails does not require the same gear as a high-altitude trek, where the elements can be particularly harsh. Several factors need to be considered:
- The weather: rain, wind, high or low temperatures, and humidity levels.
- The intensity of the activity: a short, leisurely hike and a demanding climb require jackets with different properties.
- The duration of the outing: a day hike does not necessarily require the same level of protection as a multi-day trek.
- The type of terrain: whether in forests, mountains, or plains, exposure to the elements can vary.
A good hiking jacket should regulate body temperature, provide protection from wind and precipitation, and remain breathable to prevent moisture buildup.
Essential Criteria to Consider
Waterproofness and Breathability
Waterproofness is often the first criterion people consider when choosing a hiking jacket. It is measured in mm of water column and indicates the fabric's ability to withstand water pressure before it penetrates the material. A jacket with a waterproof rating of 10,000 mm can handle moderate rain, while a model rated at 20,000 mm is designed for extreme conditions.
Waterproofness should not be confused with water repellence. A water-repellent jacket repels water on the surface thanks to a special coating, but it is not designed to withstand prolonged exposure to rain. This coating can be enhanced with a finish or a membrane, such as the well-known Gore-Tex, which provides effective protection while maintaining good breathability.
Breathability is another crucial factor. A fully waterproof jacket that traps perspiration will quickly become uncomfortable during intense activity. That’s why the best jackets combine waterproofness with the ability to allow moisture vapour to escape. Some jackets are equipped with underarm ventilation zips to improve airflow and reduce condensation.
Thermal Insulation
When hiking, managing body temperature is essential to avoid overheating or getting too cold. Thermal insulation depends on the jacket’s material, which can be either natural down or synthetic. Down jackets are lightweight and provide excellent insulation, but they lose their effectiveness if they get wet. In contrast, jackets with synthetic insulation retain their insulating properties even in damp conditions.
Weight and Packability
For long hikes or trekking, minimising backpack weight is essential. A lightweight and packable jacket will be easier to carry.
Fit and Comfort
The comfort of a jacket is not just about its fabric or breathability. A well-designed fit ensures freedom of movement and allows for layering underneath. Features such as adjustable hood and hem, and durable zips also contribute to overall comfort.
Durability and Strength
Hiking jackets are exposed to friction against rocks and general wear over time. A tough fabric with reinforced shoulders is a valuable feature, especially for carrying a backpack.
Multiple Pockets and an Adjustable Hood
Having multiple pockets allows you to keep essential items (gloves, map, GPS) within easy reach. An adjustable hood with a reinforced brim provides effective protection against wind and rain.
The Different Types of Hiking Jackets
Lightweight, Waterproof, Breathable, and Windproof Hardshell Coats
Hardshell jackets are the best choice for harsh weather conditions. They are waterproof, windproof, and designed to withstand the elements. Featuring membranes such as Gore-Tex, they prevent water from seeping in while ensuring good breathability.
Strengths:
- High waterproof rating (often > 20,000 mm).
- Excellent wind protection.
- Good breathability (thanks to the fabric's microscopic pores).
Warm, Water-Repellent, and Windproof Softshell Jackets
Unlike hardshell jackets, softshell jackets are not fully waterproof, but they offer excellent breathability and effective water repellence against light rain. They are ideal for hiking in dry weather, during the shoulder season, or for intense activities requiring good moisture wicking.
Best suited for:
- Active and intense hikes.
- Cool, dry climates.
Insulated Jackets (Synthetic or Down)
Insulated jackets are ideal for staying warm while hiking. They can be filled with either down or synthetic insulation, offering a great warmth-to-weight ratio.
Hybrid Jackets
This type of jacket combines multiple technologies, such as softshell and insulated materials, to provide a good balance of warmth, protection, and breathability.
Which Jacket Is Best for Each Type of Hike?
The choice of a hiking jacket depends on several factors: the weather, the intensity of the activity, the duration of the outing, and the terrain. Here’s how to choose the right garment based on the climatic conditions and type of activity.
Summer Hiking and Hot Weather
In summer, the main challenge is finding a jacket that provides protection from the wind and the elements while preventing overheating. In hot weather, it is essential to choose a lightweight, breathable jacket that efficiently wicks away moisture.
A softshell jacket is often an excellent choice, as it is windproof, offers a slight level of insulation for cool mornings, and has water-repellent properties in case of a brief shower. If the weather is completely clear, a simple ultralight windproof jacket with underarm ventilation and zip vents may be sufficient.
Another important factor to consider is the fabric’s UV protection, as sun exposure can be intense in both mountainous and open terrain. Some jacket models are designed with technical materials that block UV rays while optimising moisture transfer.
- Softshell or lightweight windproof jacket.
- Good breathability to wick away body moisture.
- Protection from wind and the elements.
Winter Hiking and Extreme Conditions : Fully Waterproof Jacket
When temperatures drop and atmospheric pressure becomes unstable, a warm and protective jacket is essential. In winter or at high altitude, the ideal combination follows the three-layer principle:
- A breathable base layer, such as a fleece jacket, to retain warmth and wick away body moisture.
- An insulating mid-layer, such as a down or synthetic insulated jacket.
- A waterproof and windproof outer layer, like a hardshell jacket with a Gore-Tex membrane for high-level waterproof protection.
Waterproofness is a key factor, especially if the jacket will be exposed to sleet or continuous rain. A model with a waterproof rating of over 20,000 mm is recommended for extreme conditions.
Another important aspect is the hood: an adjustable, helmet-compatible hood is a real advantage for alpine hiking. It is also essential to choose a jacket with durable zips, an adjustable hem, and well-placed pockets to store gear while keeping hands warm.
- Layering system: insulated jacket + waterproof hardshell.
- Underarm zips for temperature regulation.
- Enhanced insulation and an adjustable hood for cold protection.
Mountain and High-Altitude Hiking : Waterproof Outdoor Jacket
At high altitude, conditions can change rapidly. It is therefore essential to have a versatile jacket that provides waterproofness, thermal insulation, and good breathability. A hardshell jacket is generally preferred, as it effectively protects against wind, precipitation, and temperature fluctuations.
Models featuring a membrane such as Gore-Tex are ideal, as they offer good breathability while preventing water ingress. If the hike involves long demanding climbs, it is recommended to choose a jacket with underarm ventilation zips to optimise moisture wicking.
In addition to a waterproof jacket, a packable insulated jacket can be carried in the backpack to provide extra warmth during breaks or overnight stays at high altitude.
- Gore-Tex waterproof jacket with ventilation zips.
- Packable insulated jacket as an extra layer for camping.
- Durable fabric to withstand friction against rocks.
Day Hikes vs Multi-Day Trekking
Your jacket requirements will also vary depending on the duration of the activity.
- Day hikes: For a short outing, there’s no need to carry an overly technical jacket. A softshell jacket may be sufficient if the weather is stable, while a lightweight hardshell jacket is a better choice if rain showers are expected.
- Multi-day trekking: On a trek, weight and packability are key factors. A waterproof Gore-Tex jacket combined with an ultralight insulated jacket is an excellent choice. It is also essential to select a durable model that can withstand friction against rocks and repeated contact with a backpack.
For backpacking, a jacket with multiple well-placed pockets is a great advantage for keeping essential items within easy reach. Waterproof zips, an ergonomic hood, and abrasion-resistant fabric are also important features to consider.
Men’s and Women’s Jackets for a Perfect Fit
Hiking jackets are designed to provide maximum comfort and performance. Brands offer both unisex models as well as dedicated men’s and women’s versions to suit different body shapes. Whatever your preference, you’re sure to find the right fit in terms of size and even colour.
