Product Insights
Le Vrai Claude 4.0, K-Way's fourth-generation revival of its 1965 packable jacket, uses a 100% recycled polyamide shell to deliver wind-and-waterproof performance equal to the original. It upgrades the drawstring pouch to a zip pocket that converts into a waist pack, which can be worn as an accessory when the jacket is deployed. The jacket folds into this waist pack for cycling, eliminating the need for an extra bag. However, its 10,000mm/10,000g ratings demand rigorous maintenance: tech wash every 10–12 wears, avoid fabric softeners and bleach, reapply DWR when beading fails, and never store damp to prevent membrane hydrolysis, as the factory DWR degrades within-season without proper care.
