Unisex Zoa Rain Shell (Midnight Blue)

Dear Team The rain jacket serves its purpose well, and I am very satisfied with it. However, since I have had issues with zippers in the past and the ones on this jacket are quite stiff, I am a bit concerned that they might get damaged with frequent use. Additionally, I would appreciate it if you could let me know how to properly wash and care for the jacket. Many thanks Kind regards - Markus
