For affordability, purpose of use, and quality, this is a terrific piece of outer-shell wear. Design, materials, stitching, zippers, draw-string cords, pockets, hood, all the specs are good quality, and function well. Lightweight, too, and with its own stuff sack. Impressive.

If, after a few uses, however, this jacket ends up not keeping the rain off (nor the user inside it dry), I'll modify this review. But, so far, it's been a terrific addition to the gear kit. Mind you, this jacket won't be taken up Mt. Everest by its user, but will be used as standard rain-protective wear and for moderate backpacking, or in an emergency situation.

But, as with most waterproof gear, when it gets dirty, the jacket should be washed to keep up its waterproofing function, if not then also treated with a good, waterproofing spray. (Sometimes washing is all that's necessary to unclog the fibers and restore the material's waterproof protection.) At the time of writing this review, a Sierra Designs rep recommended using "NikWax Tech Wash" to prolong the waterproofing efficacy of their outer-shell wear; and "NikWax" or "McNett" waterproofing sprays for fabrics.

As for sizing, I don't know about other folks, but this purchaser had to go one size up from a normal large size, which is highly unusual for the person I bought it for. To be sure on the right measurements (length, shoulder room, etc.), you might want to contact Sierra Designs directly. They're friendly, courteous, and very helpful.
