Our Brule Hoodies are made from Polartec® Alpha Direct® fleece. This ultra-lightweight material offers exceptional loft and insulation and is very breathable. Used on its own it makes a great active layer, and when paired with a shell it provides excellent base-layer loft. We have three different weights of Alpha Direct® fleece (60, 90 and 120 grams per square meter) which covers the spectrum of weight and warmth. Please see the final photo in the gallery for examples of the hood types.
