Great Scott! This is LIGHT.
This jacket was purchased for an outside layer for very cold, winter road biking. I am pleased with the quality. The waterproof seams and zippers are a must for wind and snow/rain. The drop back is an added bonus and it fits perfectly into a bike jersey pocket (without the usual cramming)if the weather gets warm.

Crazy Light!
This shell is crazy light (7.8 oz for XL) and breaths well. Tried it out in a heavy rain shower and kept dry while not sweating like crazy like I would with my Marmot Rush which is about the same weight at 8 oz. The arm holes are tight so size up at least 1 size. At 6'2 210lbs I usually were a Large but the XL worked better.

Great Jacket
Excellent jacket. It's almost hard to believe such a lightweight jacket could be so durable and waterproof. This jacket runs a little longer than other comparably sized Mountain Hardwear stuff, which usually runs very small.

For Southern Calif. all you need over layering
I wear this hiking, biking, long walks. The stretch is amazing. Cinch up the neck and hem and you're sealed in yet allowing sweat to escape. It's so lightweight and stretchable you forget you have an outer shell on. Waterproof zippers seal the deal!

Waterproof and rediculous stretch!!!!
If you run in the rain or are looking for a super light shell for wet and windy days this is your jacket. I want to compare this jkt to my MH transistion jkt during the nordic season. I'll report back when the XC season starts up.
