After unsuccessful last drop I bought Whirlwind hoody somewhere else. It is indeed very lightweight but seems to be durable and can be great for layering in warmer weather. It's too thin for winter use. Packs pretty well too. Windstopping is moderate. I used it this spring as a mountain bike jersey replacement on windy days and still going to use it occasionally now on colder days. It's great backpacking / bikepacking garment. Not sure though if I would take both this hoody and lightweight rain jacket in one trip, because lightweight rain jacket like OR Hellium will work both as windstopper and rain protection.
