- Elasticated waistband, adjustable on either side.
- Flat elasticated waistband that's compatible with wearing a harness.
- Pre-shaped knees, reinforced lower leg for protection from crampon spikes.
- Elasticated drawstring and adjustable lower leg
- Two zip pockets.
- Zip fly.
The full-length two-way zip opens from the top, letting you fit crampons or skis, and allows you to relieve yourself without having to remove the overtrousers.
We measure a fabric's resistance to a water column, in mm (based on the ISO 811 standard). The higher the water pressure resistance, the more waterproof the fabric. A component with a 2000 mm waterproof rating can withstand 2000 mm of water pressure (which is roughly equivalent to a rain shower lasting 2 hours).
With waterproofing over 30,000 mm, Alpinism overtrousers offer an extremely high level of waterproofing.
To find out whether a fabric is breathable, we test its evaporate resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more moisture, generated by an active body, is evaporated, and therefore the higher the fabric's breathability.
We consider that if:
- RET < 9 = highly breathable fabric
- RET > 12 = slightly or not breathable fabric.
These trousers are 9
In addition to the main fabric's breathability, these trousers have been designed with two side zips, enabling air flow for temperature regulation and improved ventilation.
Full length two-way zip
The new generation two-way zip offers the same waterproofing as a classic silicone zip (similar to those on pockets) while being more flexible, which improves the compressibility of the overtrousers when packed away. Plus, this zip is easier to handle, which helps to make it longer lasting. The two-way zip and full length opening, allow you to fit or remove trousers, crampons, skis, which is an added bonus during a storm.
