3SP and full zip jacket? Brilliant!
I owned a way earlier version of this jacket decades ago, in a navy blue. My adult son wears that today, and it's pretty much as good as new. If Sporthill makes products with that kind of longevity, and with the magical qualities of 3SP for comfort across such a wide range of temps, they can charge just about whatever they like and I'll be a customer. I don't disagree with previous commenter's rec of adding a pit zip for an even wider-ranging high output comfort zone, but I'm happy exactly as is!
