If you want a fast, light and quality rain jacket, this is the one for you. Being a rock climber, I need something that will keep me dry through a flash storm but also very packable and light. This was my solution and I find myself using this jacket almost every day. Not only is it a fantastic rain jacket, it is also a great wind breaker and a layering piece. I throw this jacket over my Atom LT and it keeps me dry and warm throughout my daily commute and when I go on weekend backpacking trips, this jacket stuffs into a water bottle pocket for easy access.
With that said, this jacket is made with Gore-Tex Paclite. At first, it performs well but after heavy use, the face fabric starts to bleed through. This does not affect the water-proofness factor of the jacket, but if the face fabric bleeds, it greatly reduces the breathability of the jacket. I've already treated my jacket with DWR twice in the last 6 months. Paclite is great but if you want a truly bombproof jacket, I would recommend a better fabric, something like the Alpha LT or the SV. These jackets use better face fabric that beads the water better.
