More than 50 years ago, everyone venturing into the high mountains wore bulky corduroy trousers. That was the standard of the time, and technical progress has changed and significantly improved things. Today's mountain trousers have the enormous advantage of combining numerous technical qualities with a much lighter weight — allowing everyone to fully enjoy the scenery without enduring the unnecessary effort of dead weight on their legs. But how do you choose mountain trousers? There are many possible criteria, but let's look at the most important ones — a solid framework to help you make the right choice for your next adventures on the high peaks!
What to look for when choosing mountain trousers
Intended use
It goes without saying that the characteristics of a good ski trouser are not the same as those of a hiking trouser or a mountaineering trouser. If you dedicate time to a specific activity, it's important to choose a trouser specifically designed for that use. It will differ not only in fabric construction but also in design, resistance to impact and abrasion, and activity-specific features.
Weight
The more a trouser is designed for high-altitude use and mountaineering, the less lightweight it tends to be. Reinforcements at the ankles and knees, and the thickness of the fabric, all add weight — but they also generally make the trouser more versatile and built-to-last. That said, many mountain trousers designed more for hiking or milder seasons remain very lightweight and easy to wear.
Protections and reinforcements
These additions are essential as soon as you take on a committing activity — that is, mountaineering, high-mountain hiking or skiing. Only light summer hiking on fine days requires no specific reinforcements.
Reinforcements at the ankles, knees and seat — more or less robust and wide — contribute greatly to the lifespan of your trousers, as well as to your safety. A small impact can cause real damage, and protections significantly absorb the various knocks you can take during your activities.
Integrated gaiters
These are generally found on the most versatile and technical models. They are most effective and useful in fresh snow, as this is the primary factor in moisture spreading. In other cases, the lacing systems or bellows Velcro closures found on many trousers are sufficient.
Waistband and/or braces
In the mountains, you're often carrying gear (backpack) or wearing a harness (mountaineering). That's why you need trousers with an effective and secure retention system. You can choose trousers that combine both, but bear in mind that brace systems are better suited to intense activities like mountaineering. The ideal is to choose mountain trousers with a removable brace system — a genuinely versatile solution that's worth its weight in gold.
Garment stretch
Depending on the model and materials used, the elastic effect — the garment's stretch — varies. A light stretch is preferable to an aggressive one. Too much stretch will stiffen the fabric and restrict freedom of movement. On the other hand, a trouser with no stretch at all will quickly become uncomfortable in any activity requiring good mobility. As a rule, the stretch in quality mountain trousers is well-calibrated and delivers good freedom of movement in all situations.
Thermal protection
This is an important point for all high-altitude and winter activities, where it's better to choose trousers that protect against the cold. The thermal protection of your trousers should be adequate, but not necessarily excessive. Your legs are in motion and already generating heat. That said, it remains an important point to check — especially in the high mountains. It will essentially be the windproof properties of the fabric that are key to keeping you well protected.
Water repellency and waterproofing
This too is an essential characteristic in the demanding conditions of the high mountains — one that deserves even closer attention than the previous point, as it directly governs your comfort. Nothing is more unpleasant than having wet legs because a trouser is neither waterproof nor breathable (moisture-wicking). Look closely at waterproofing test results and statistics, and know that for high-mountain use you should choose trousers with approximately 10,000 mm of water-column resistance.
Breathability
This characteristic is important whatever activity you practise — and all the more so for dynamic activities. In skiing, for example, a non-breathable trouser is a dealbreaker: your perspiration will quickly build up on your legs, creating a chilling effect the moment you stop. The breathability of the materials used is essential when choosing mountain trousers that are pleasant to wear and genuinely comfortable.
Other features
When choosing mountain trousers, pay close attention to the cut, number of pockets, closures, etc. These are details, but they can make a real difference to how much you enjoy wearing the trouser. Finally, in snowy conditions, don't overlook trousers fitted with Recco technology. A simple sensor is embedded in the fabric, allowing rescue teams to locate you more quickly in the event of an avalanche — a small but potentially life-saving addition!
Choosing mountain trousers is a genuine investment. By selecting a quality, reliable product, you're choosing a garment that will last many seasons and bring you great satisfaction — and real pleasure in pursuing your mountain activities with comfort, freedom of movement and wellbeing!
