The Arcteryx Alpha IS Jacket is an amazingly light and fully waterproof insulated jacket that offers superb levels of warmth and protection from the harsh winter elements. It is ideal for cold, snow and wet conditions and provides excellent breathability making it a perfect jacket for the Scottish mountains.
The fit is of a regular cut with e3D - ergonomic 3-Dimensional patterning that is designed to enhance a greater freedom of movement for sport-specific activities.
The jacket benefits from ThermaTek which is a hollow core continuous fibre that has been treated with a heat activated DWR coating. This provides the jacket with a hydrophobic insulation that retains it's ability to loft quickly even after being compressed in your pack. The insulation is laminated to the Gore-Tex membrane to ensure that it will remain in place and retains the jackets maximum breathability. The 2 Layer Gore-Tex outer shell is durable yet still lightweight and also benefits from a water repelling DWR finish. The shoulder areas on this jacket have been given an extra layer of Coreloft insulation to assist in keeping you warm, comfortable and protected from whatever conditions the winter throws at you.
The Alpha IS is a versatile jacket, as it can replace your midlayer and shell or it can be used as your belay jacket.
