The Arc’teryx Alpha LT Jacket is the lightest fully featured alpine-focused shell on the market, and has been designed for moving fast in alpine conditions. The Alpha LT features the tough, waterproof and breathable protection of GORE-TEX Pro 3L fabric, and comes with e3D patterning for enhanced mobility.
| GORE-TEX® Pro | Provides the highest level of durable waterproof/breathable performance available. GORE® Micro Grid Woven Backer delivers garments that are consistently the lightest and most compact in the industry. GORE-TEX® Pro has a sparsely woven nylon backer that is twice as durable as traditional tricot liners and allows moisture vapour to pass quickly through to the GORE-TEX® membrane. |
| N40p-X GORE-TEX® Pro 3L | A high tenacity nylon face fabric with a flat filament warp yarn and false twist textured fill yarn, backed with a micro-grid woven backer. This fabric is lightweight, durable, and has excellent water repellency. DWR finish |
| DWR: | A finish applied to a fabric that will bead-up water on its surface to stop it soaking into the fibres. This maintains breathability and shortens drying times |
| Expedition fit | Has a larger cut that accommodates multiple layers without binding or restricting movement. |
| E3D patterning | Ergonomical 3-Dimensional patterning brings an additional level of articulation to provide enhanced mobility. E3D refers to an allowance in the garment patterning to provide extra gusseting and/or articulation in key joint areas to allow for maximum movement. |
| WaterTight™ | The world’s first WaterTight™ zippers to pass the W.L. GORE® extreme wet weather test. |
| HemLock | Found on many of Arc'teryx's climbing jackets, it prevents your jacket riding up thanks to a feature that lets you clip the hem to your harness. |
