Sierra Designs has introduced a completely novel and exciting product to the realm of rain jackets with its new Stretch Rain Jacket. This new technology, however, still has a way to go to hold up to the waterproof/breathable standard of the other rain shells in our review. In our tests, we found the fabric to be too thick to support high aerobic activities, and too porous to withstand anything beyond a light rain. The stretchy factor, coupled with the stellar hood and sleek design make it a great option for around town. If you had only one jacket to throw in you car for urban missions, and you wanted it to look nice, keep you dry in a drizzle, or add warmth in a sudden cold snap, this is a great jacket. It is a good compromise of many components.
Sierra Designs has discontinued the Stretch Rain Jacket.
