Mountain-living isn't all roses. True, sunrises and sunsets are spectacular, seasons explode in color, and abundant clean air and water keep you breathing deep and living well. However, those winter storms and spring deluges test you, as if to say "Can you handle the mountains in less than idyllic conditions?" Thankfully that answer is a resounding yes with help from the Beta LT Jacket. At a mindbogglingly low weight of 10 ounces, this jacket is equally at home on back-country trips as it is around town and the GORE-TEX Pro 3L fabric guarantees you stay dry no matter what. The supple yet durable fabric isn't crinkly and moves quietly with you for your fast and light alpine ascents. The trim fit of the Beta LT Jacket keeps a low profile yet the e3D Ergonomic 3-Dimensional patterning (fancy speak for movement inspired design) ensures that you mobility is unrestricted. Storm features such as WaterTight zippers, cuff tabs, hem drawcord, and a fully adjustable storm hood let you fully seal out the elements while you stay warm and dry. You're mountain hardy, shouldn't you have a jacket you can same the same thing about?
