Rain Shield O2 Hooded Rain Jackets (Yellow)

I was looking for a lightweight, breathable raincoat that I could stuff into my hydration pack in case of rain during a hike. This jacket is exactly what I wanted.

Weight: about 6 ounces - hard to find anything lighter

Waterproof: I've only been rained on once with it, but it seemed to do the job. I read a detailed review where the reviewer said he shaped part of the jacket like a cup, filled it with water, and left it sit for 24 hours with no leaking (he claimed that Gore-Tex is not as waterproof).

This is my 2nd rainshield O2 jacket - love the first one so much. Just wanted another one a tad larger for wearing over heavier under-layers.

The jacket is plenty large so I do not have to put undue strain on it when putting it on. Just know that this product is very light weight and by that factor a little flimsey.
