CimaCuin: Innovation and Environmental Responsibility

CimaCuin insulation, an exclusive technology developed by CIMALP, offers an unprecedented balance between warmth, lightness and respect for the environment. This advanced system uses 800 cuin padding and 150 g (size M) of ethical RDS (Responsible Down Standard) certified down, ensuring excellent thermal protection with a reduced ecological impact. Selected according to rigorous criteria of responsible origin, the down ensures optimal distribution of body heat even in the most extreme conditions, offering reliability and resistance to humidity. In addition to representing a cutting-edge technical solution, CimaCuin demonstrates CIMALP‘s concrete commitment to a more sustainable future. Each garment is produced through responsible processes and high-quality materials, reducing environmental impact without sacrificing performance. This innovative approach redefines the standards of technical clothing, responding to the needs of the most demanding explorers and promoting more conscious consumption. Thanks to the perfect fusion of advanced technology, ultralight design and sustainable values, CimaCuin positions CIMALP as a leader in outdoor innovation. The French company has a clear goal: to provide adventurers with cutting-edge solutions, ensuring high performance without compromising respect for the planet.

Maximum performance with minimum weight

In mountaineering, the weight of your equipment can significantly impact performance and safety. For this reason, Meru and Lory have been designed to offer the best balance between thermal insulation, lightness and resistance, without compromising on technicality. Thanks to an optimised design and the use of innovative materials, these down jackets guarantee warmth and protection without weighing you down, allowing agile movements even in the most demanding conditions. Another key feature is their exceptional compressibility. Easy to fold and compact, they take up minimal space in your backpack, making them ideal for those looking for versatility and practicality without adding unnecessary weight. Perfect for long climbs, challenging expeditions or for those looking for a high-performance and compact garment, Meru and Lory are the ideal choice for tackling the mountains lightly, without sacrificing protection and reliability.

Water repellent treatment for optimum performance

To ensure constant effectiveness even in humid environments, both the outer fabric and the down padding are treated with an eco-friendly and durable water-repellent finish. This treatment prevents the down from absorbing water, avoiding the loss of insulating capacity and ensuring optimal thermal comfort in every situation.
