What Our Gearhead(R) Experts Are Saying:"This lived in my daypack through a week of unpredictable fall weather, and I pulled it out more times than I expected. It's thin enough that I forgot it was in there until a cold gust hit on a summit and the down fill saved the afternoon."Some layers earn a permanent spot in the bag, and the Stratus Vest is one of them. Canada Goose designed it around the idea that warmth shouldn't come with commitment, so it rides along on hikes, flights, and everything in between without ever feeling like dead weight. Down and feather fill does the heavy lifting through the core, cutting the chill the moment temperatures dip. The Ultra Light Ripstop shell holds up against wind and stray drizzle without adding stiffness, and two zippered hand pockets plus an interior security pocket give you somewhere to stash the small stuff. A drawcord at the hem seals in heat when the wind turns, and the whole thing folds back into its own pocket the second you're done with it, ready for the next unplanned adventure.
