Arcteryx Proton LT Jacket Mens

The Mens Arcteryx Proton LT Jacket is an insulated jacket for delivering lightweight warmth while on the mountain. Worn as a softshell or midweight insulated midlayer, the highly air permeable Proton LT Jacket is adaptable, versatile and designed to manage the dynamic demands of rock, ice and alpine climbing. Advanced material technologies balance wind, weather and thermal protection while allowing air to pass freely in and out. This ability to self-regulate helps prevent vapour accumulation and allows the Proton LT to deliver comfort over a wide range of temperatures, conditions and output levels. Filled with Coreloft, the synthetic insulation inside the Proton LT Jacket is light and highly compressible like down, yet retains its warmth in humid and wet conditions, drying quickly if it gets wet. But that shouldn't be too much of an issue as the outer face fabric of this ArcTeryx LT Jacket resists moisture and wind to give you enough time to throw on a shell should conditions deteriorate. Designed to perform both as a soft-shell outer layer and as a mid-layer under a waterproof shell, the Arc'Teryx Proton LT Jacket is an all-around, versatile jacket that balances warmth and airflow.
