Southern Divide's intelligent layers allow the long sleeve crew neck to slide effortlessly over the base-layer. Designed with a higher neckline than our base-layers to avoid bunching whilst decreasing the amount of powder entering the back. No seam line on the shoulders to eliminate any discomfort whilst carrying load up the mountain and an extended drop-tail to cover the backside whilst you work hard getting down the mountain. Southern Divide's Merino is lightweight, quick-drying, moisture-wicking and thermo-regulating that is suitable for all conditions.
