The Southern Marsh FieldTec™ Dune Pullover was created with one thing in mind - transitional performance. We didn't focus just on the super-soft fleece shell or the brushed polymesh interior. Just like you, your outerwear needs to be able to handle whatever you throw at it: cool early mornings, warm mid-day sun, and the chilly late nights. The FieldTec™ Dune Pullover was engineered to help control and regulate your temperature throughout the day. The waffled grid pattern was designed to allow heat and moisture to flow out of the jacket while at the same time block the crisp fall air from entering. We included a vertical side pocket that's just the right size for a phone and topped it off with taped contrast zippers.
