"A shell that you can shove in your pocket for those unpredictable weather conditions, the Mountain Hardwear Ghost Whisperer Anorak jacket weighs
under 2 ounces
and is wind and water resistant. 7D fabric makes this a durable lightweight option for those days when the clouds start to creep towards the trail head. A deep neck zipper for ventilation and reflective trim for visibility makes this jacket ideal for long trail runs on either side of summer."
How rain resistant is it?
