Encasing the insulation is DRILITE Loft 40D outer fabric, a windproof, highly breathable, and water-resistant shell that offers robust protection against harsh weather without sacrificing packability. Built to withstand the demands of remote environments, its equally suited to mountain routes and cold urban settings.

The fully insulated, removable hood is designed for versatility, featuring dual frontal adjusters, a rear volume adjustment tab, and a wired visor for maximum visibility and protection in exposed conditions, even when wearing goggles or a helmet. Storage options include two large, insulated hand pockets for gloves or accessories, plus an internal security pocket for essentials. When not in use, the Lightline compresses into a compact stuff-sack for efficient stowage.

A proven companion for cold-weather pursuits, the Lightline Jacket delivers dependable warmth, minimalist design, and technical detailing, trusted by climbers, mountaineers, and outdoor professionals around the world.
