Sizing Chart: 


One of the most versatile fleece jackets Arc’teryx has ever designed, the Delta LT provides effective warmth for little weight and layers easily under a hardshell. Made from Polartec® Classic 100 micro velour small grid, the Delta LT is highly air permeable, dries quickly and packs to a compact size. As a standalone, the jacket adds light insulation most suitable for higher output in cool conditions or to cut a summer evening temperature drop. Under a shell, it works as a lightweight midlayer.


Purposeful design is an Arc’teryx commitment. With a focus on athletic freedom and performance, the Delta LT’s women’s specific design enhances ergonomic freedom and performance comfort for the female athlete. The jacket’s Trim fit stays close to the core allowing it to work more efficiently under shell layers. Articulation prevents the sleeves from riding up when the arm is bent, and gussets under the arms make it easier to extend reach. A slight drop hem adds coverage.


Simplicity requires disciplined design, as reflected in the Delta LT’s thoughtful feature feature selection. The full front zip uses a nonlocking slider that can be unzipped with a single hand for instantaneous heat dump. The high collar seals in warmth with a low profile that layer easily under a shell. Two hand pockets zip closed to securely stow small items, and a small, low profile laminated sleeve pocket is easily accessed while wearing a pack or harness.
