This jacket is a must have for anyone that needs a lightweight, packable, windproof, water resistant shell. I use it on ski patrol for those hot spring days as a layer under my patrol vest. I have been drenched by water from the end of season pond skim and the water ran right off the jacket. Its a perfect layer for backcountry skiing as it packs and breathes so well. I have been using it for mountain biking on chilly descents and its the perfect jacket for hiking. I have not ever been so excited by a lightweight soft shell.
