It is thin, light, and fits easily into the small travel pack/bag it comes with so I can keep it in my backpack or a large purse. Works well for layering under and keeping off the frequent Seattle rain! One thing I didn't realize from the picture is that the jacket torso flares out at the end. Good for light rain, but nothing too heavy as you will feel dampness coming through.

UPDATE: After five years of occasional use, this jacket has seen it's last days as the inner seam seals are falling apart and the white coating has worn through. It's served me well but I won't be repurchasing as I'd like one that withstands more than a drizzle.
