While the coolness of the evening is more than welcome in more southerly climes, we reach for a warm blanket later in the day in more northerly climes. Skin-friendly cotton, light alpaca or soft merino wool are the preferred materials here, as they also feel very comfortable in direct contact with the skin. Blankets made of linen and cotton are particularly kind to the skin. Linen also has a cooling effect because it absorbs and wicks away moisture quickly - ideal for tropical nights.
