Alongside Mountain Hardwear, REI Co-op is a perennial favorite for very cleverly designed, well made gear, and the Flash 22 is an archetype of why that’s the case. REI Co-op Flash 22 Pack Now 30% Off $60 $42 at REI Key Specs Capacity 22 liters Weight 14 ounces Gender Unisex Material bluesign-approved 70-denier recycled ripstop nylon with polyurethane coatingIt hits the sweet spot in terms of size. Given that you won’t be carrying a campsite on your back with the Flash 22, it’s more than adequate. At a svelte 14 ounces, the Flash 22 isn’t the lightest lightweight daypack out there, but it is light. I also take the Flash 22 when I’m the only one on a remote trail, far from gas pumps and picnicking couples.
