Versatile, lightweight, microfleece jacket that works as a midlayer or as a standalone in cool weather. One of the most versatile fleece jackets Arc'teryx has ever designed, the Delta LT provides effective warmth for little weight. Quick drying, air permeable Polartec? Classic 100 micro velour small grid and articulated construction focused on ergonomic freedom and performance comfort make the Delta LT extremely versatile. The Delta LT layers easily under a hardshell, but as a standalone adds light insulation for higher output in cool conditions. A low profile, high collar seals in warmth.
