Sierra Designs WindStopper Jacket

Not as warm as 200 weight fleece, until you're in the wind. I live in a windy place, New Mexico, the weather changes constantly. This jacket makes it so I don't have to take my shell on day trips, yet the huge chest vents, arm vents,(not pit zips), and hand pockets allow plenty of air into the jacket. One can layer underneath it to be comfortable in 30 degree weather.

I admit Sierra Designs' products aren't the best items, ie. stiching could be more reinforced, flaws are common, and more attention could be granted overall. But for the price it's a good item to own if you are around strong wind.
