High-quality stretch fleece. The NXT Polarlite Jacket is a lightweight, versatile fleece jacket with a full-length zipper that offers outstanding thermal regulation for its weight. The fit of the technical fleece is specifically designed for climbing. Reinforcements in the shoulder area, elbows, and forearms protect against abrasion from rocks or when carrying a backpack. The grid fleece construction made from 100 percent recycled polyamide provides excellent thermal performance thanks to its channel structure, while maintaining a low overall weight and compact pack size. The zippered left chest pocket is perfect for storing small items, and the elastic cuffs and hem keep out wind and cold. The NXT Polarlite Jacket is the ideal technical midlayer to complement the base layer for a summer alpine layering system.
