When you want a jacket that offers great breathability and a little bit of warmth for a really low weight, look no further than the Rab Vapour-Rise Lite Alpine Jacket. It'll also keep a little wind and snow off your shoulders as you huff and puff up that sweet alpine ridge. This piece lives near the breathable end of the waterproof/breathable spectrum and works really well when used in conjunction with an insulated jacket or rain jacket. Additionally, the micro-fleece drop liner in this piece adds a bit of warmth and comfort to an otherwise ultralight softshell. It performed poorly in our waterfall test causing it to fall behind more protective jackets like the Arc'teryx Gamma MX Hoody and Black Diamond Dawn Patrol Shell. However, if you consider ultra-breathability paramount over weather resistance, then you should know that the Lite Alpine out breathes either of these jackets. Overall, we loved the Lite Alpine and found it very wearable through a variety of conditions. It epitomizes much of what an active softshell should be.
Now simply called the Vapour-Rise Alpine Jacket, Rab updated this softshell with a slightly new look featuring a new hood and adjustable cuffs. Scroll down for a more detailed comparison of the new Vapour-Rise Alpine Jacket and the older version.
