Considered design and careful construction make the Capilene Thermal Weight Crew from Patagonia the ideal wintertime base layer. Cut from Polartec Power Grid, the fabric keeps the wearer comfortable over long periods of time with its moisture-wicking, breathable and warming qualities. A full flatlock seam construction, alongside offset shoulder seams, eliminates chafing and increases comfort, especially when in use with a backpack, while thumb loops provide a stable fit and the drop hem increases coverage.
