Product details:

No reason to cancel the hike if you've got the Mountain Hardwear Acadia Jacket stashed in your pack. This lightweight rainshell stuffs down small, so there's never a reason not to have it on hand, and it features a 2. 5-layer membrane to protect you from light rain or wet bushwhacking explorations. The adjustable hood keeps you well defended in stormy weather, while zippered underarm vents help you cool off if you continue to hike through the drizzle.
