The Loft Jacket is a new high-tech product that was successfully tested in real life by Christophe Dumarest when he climbed the ten north faces of the Ecrins massif unaided in October 2008. Developed for mountain use, the Loft jacket combines Primaloft® with Lafuma’s Climactive® membrane to ensure full protection from extreme climatic conditions. It is light, soft and water repellent, as well as offering optimal breathability and compressibility thanks to its use of PrimaLoft®.
