Fleece’s insulating properties make it ideal for activities where you need additional warmth, such as skiing, snowboarding, or winter hiking.

Moisture Management

In addition to providing insulation, fleece is also highly effective at managing moisture. Fleece has the ability to wick moisture away from the skin and disperse it across a larger surface area, facilitating evaporation. This keeps you dry and comfortable during physical activities where sweat is inevitable. Fleece also dries quickly, which is beneficial if you need to wash and dry your middle layer overnight. The moisture management properties of fleece make it suitable for high-intensity activities or situations where you may be exposed to rain or snow.

Exploring Down

Down is a natural insulating material that is often used in middle layers for its exceptional warmth-to-weight ratio. Understanding its unique properties will help you make an informed decision when selecting a middle layer.

Exceptional Insulation

Down is the soft, fluffy layer found underneath the feathers of ducks and geese. It is made up of clusters that have a high loft and trapping ability, allowing them to retain heat effectively. Down creates pockets of air within its structure, which provide insulation by preventing the escape of body heat and blocking cold air from getting in. This makes down an excellent choice for cold weather activities or situations where weight and packability are important considerations.

Issues with Moisture

While down offers unparalleled insulation, it has one significant drawback when it comes to moisture. When down gets wet, it loses its ability to retain heat and becomes heavy. Wet down takes a long time to dry, which can be problematic in damp or humid environments. If not properly cared for, wet down can contribute to hypothermia and pose significant risks to your well-being. To combat this, it is essential to protect your down middle layer from moisture by using an outer shell or ensuring you have an extra dry layer to change into when needed. There are also water-resistant and hydrophobic down options available that offer improved performance in wet conditions.
