Merino wool has long been heralded as nature's best temperature-regulating fabric. With the ability to hold onto heat in cold temps, manage moisture in humidity or during strenuous activity, and dry quickly in any type of wet environment, there's no doubt as to why the leading companies choose merino wool for their most important layers: the foundation.
For chilly backpacking, mountaineering, or skiing trips, and for humid hiking, paddling, and climbing excursions, the Outdoor Research Alpine Onset Crew are the base layers you need to keep your temperature in check. Using 83% merino wool with a touch of nylon and spandex for extra mobility, each Alpine Onset piece features a trim fit as your next-to-skin layer for easy layering and efficient temperature control. A flat seam construction prevents chafing, and a lightweight, compact design makes it easy to fit an extra layer or two in your pack. Plus, merino wool naturally blocks odours - making it an easy winner that both you and your tent mate will appreciate.
