The day I got this jacket, I took it out for an hour run in variable weather that bounced between sunny, cloudy, and light snow, with temperatures hovering in the low to mid 20s. Welcome to Colorado! Air flows nicely through the mid-weight fabric, keeping me cool on the climbs. When the sun disappeared, and the temperature dropped, zipping up the scuba hoodie sealed in the warm air. I get cold easily. For me, mid 20s is right on the fringe of too cold with this jacket alone. Any colder, and a shell would have been required.

On those colder days, when temps are in the mid-20s or below, I layer this jacket with the Jack Wolfskin Pack & Go Shell. This combo makes for a perfect layering system for cold weather mountain biking, snowboarding, or other winter pursuits. It’s also a great setup for travel. The Hydro Grid has plenty of tech for athletic endeavors, but it’s not too techy for everyday wear. And the Pack & Go Shell packs into its own pocket while still offering comforts missing from many ultra lightweight shells, like pockets and a mesh liner.
