I bought this Outdoor Research jacket on sale for $99 last fall but have not worn it yet. I am currently packing for a walking tripmin the Pyrenees and am considering taking it as I like the length and the super lightweight/ minimalist design. But I want to test the waterproof-ness first, so I put it on over my clothes and stepped into the shower for 2-3 minutes. Ta-da! Kept me totally dry in the downpour of the shower.
You can read reviews here on REI:
But it is much cheaper on Amazon (if you are Petite):
Note the reviews that say this jacket runs a full size small. That is correct. I normally wear an XS ( size 2) but the Small fits perfectly in this jacket.
