3-in-1 jackets are not ideal for backcountry touring. The combined system is too heavy and not breathable enough for sustained uphill travel. The liner adds warmth that you typically do not need while skinning uphill, and the reduced breathability can lead to dangerous sweat accumulation in cold conditions. For touring, a lightweight, highly breathable shell with a separate, packable mid-layer that you can put on during stops is a much better choice.
