Climbing involves wide, sometimes acrobatic movements. Whether climbers are indoors or on the rock face, their kit must be well suited to perform in the best possible conditions. Choosing the right climbing trousers is therefore essential.
Essential criteria for choosing climbing trousers
Freedom of movement
The most important criterion when choosing climbing trousers is freedom of movement. Climbers make wide moves to reach holds and progress on the wall. A stretch fabric is therefore recommended for unrestricted movement. Cimalp equips its climbing trousers with Cimaflex® technology, for extreme flexibility. For greater freedom of movement, a fitted cut is also recommended.
Durability
Climbing involves friction against the rock, bouldering slips and falls. Trousers must therefore be tough and abrasion-resistant for outdoor climbing. Fabrics blending cotton and polyamide or nylon are ideal for this. To avoid wearing out certain parts of the trousers too quickly, reinforcements on the knees or seat are also worth prioritising.
Breathability
Climbing sessions are often intense and long. During prolonged effort or in the heat, discomfort can set in quickly. Breathable materials, sometimes featuring mesh panels or zipped vents, are ideal for improving breathability.
Comfort
Comfort is equally essential when choosing climbing trousers. An uncomfortable outfit can distract, restrict and detract from the pleasure of climbing. Lightweight trousers, soft on the inside and well fitted, without being too tight, ensure good comfort. Even when wearing a harness, you must be able to feel at ease.
Additional features for greater comfort
Adjustable waist and leg openings
Some climbing trouser models include features that improve comfort. An elasticated or adjustable belt ensures a secure fit without slipping. Drawcords and elastic at the leg openings prevent the fabric from getting in the way of your feet and allow you to see the holds more clearly.
Well-placed pockets
While some climbing trousers are very minimalist, others offer numerous pockets. They are often positioned on the upper thighs or at the back for easy access. Zip closures are also very useful for securing personal items. Cargo pockets, popular in mountain use, are too bulky for indoor climbing.
Pre-shaped knees
Pre-shaped knees allow you to raise your legs higher without pulling on the fabric. Freedom of movement is therefore greatly improved, especially on technical sections.
Flat seams
Choosing climbing trousers with flat seams, intelligently positioned, is a wise move. This will mean less friction and irritation, especially during long sessions.
Hold brush holder
If you boulder or climb demanding routes, a brush holder is a frequently appreciated addition. It is a small loop, positioned on the thigh or at the back of the trousers, to attach your brush.
Water-repellent and UV treatments
Finally, some trousers are specifically designed for outdoor use. UV protection is ideal against the heat and a water-repellent treatment offers protection from the rain.
Indoors or outdoors: choosing the right climbing trousers
Indoors
Choosing the right trousers is one of the differences between indoor and outdoor climbing. Indeed, your needs differ depending on your practice. Indoors, comfort, lightness and freedom of movement are the priority. Conditions are controlled and durability is less critical.
For indoor climbing, you can choose between shorts or trousers. They should be lightweight, stretchy and fitted with an elasticated belt to ease movement. A relaxed or fitted cut is also recommended for maintaining comfort.
Outdoors
Unlike indoors, conditions on the rock face are more demanding. Climbers are exposed for long hours to rock and the elements. Trousers that offer durability, long-lasting comfort and protection are therefore essential.
For outdoor climbing, trousers should be made from breathable materials (thick cotton, polyester, ripstop). Choose an ergonomic cut with pre-shaped knees and reinforcements at the knees or seat. These offer additional protection against friction and impact.
Features such as adjustable leg openings to see your feet on the holds, harness-accessible pockets and a flat waistband are a real bonus. Finally, UV protection or a water-repellent treatment are also recommended.
Choosing the right climbing trousers is essential for safe climbing. They must offer a good balance between comfort and performance, allow fluid movement and total freedom while remaining durable. Climbing becomes a true pleasure, both indoors and out in nature.
