The Arc'teryx Delta LT Zip-Neck Fleece Pullover exemplifies all the versatility you crave when you're headed out on a spring hike or early winter tour. This Polartec Classic 100 fleece top provides essential thermoregulation throughout the year, minimizing gear needs and maximizing pack space. Wear it over a wicking shirt for cool evening runs, as a mid-layer for high-output winter pursuits, or as expedition-weight baselayer in extreme cold. Its smooth face won't catch or bind under outer layers, so you get more out of your shirt. Arc'teryx updated the 2019 pattern to give it a more relaxed fit and longer length.
