The benchmark in hiking trousers for mountain experts. 3D Flex plus fabric, CimAlp innovation, 100% stretch, durable and ultra comfortable.

CIMALP ™ - Est. 1964 - We are Mountains

Built-to-last and highly stretchable

These hiking trousers are a must-have among mountain experts, and offer excellent value for money.

For this new generation of one of CimAlp's leading garments, our innovation teams have concentrated on the material,with the use of 3D-Flex-Plus ® technology. This fabric has been developed by CimAlp and offers unprecedented comfort and freedom of movement, thanks to an innovative combination of fibres:

  • 72% bamboo viscose for a soft, silky fabric that regulates both temperature and moisture
  • 25% polyamide for a durable garment, even for the most extreme usage
  • 3% elastane fibres combined with 3D weaving for optimal stretch.
  • DWR water repellent, anti-stain treatment

Meanwhile, we have redesigned the cut at the knees, at the rear and at the hem, which is now made from Schoeller bi-stretch Extreme Cordura® - 260g/m² for exceptional durability where it is needed most. Finally, the overall fit has been redesigned, with a fitted, ergonomic, straight cut to accompany you in your movement. The LAOS 4 will be your loyal companion in all your outdoor activities.



  • Semi-elasticated waistband with fastening
  • 2 side pockets with zip
  • 1 rear pocket with zip
  • 2 thigh pockets with flap 
  • Drawstring at the hem
  • Schoeller® Extreme Cordura® inserts: pre-shaped knees, rear and hem
  • Ergonomic cut
