Bonded Fabric - Bonded simply means the shell fabric is joined to a softer interior fabric for your comfort and warmth. The interior layer of bonded fabric (usually fleece or polyester) helps to keep you warm in frosty temperatures and protects your body from wind.
DWR [Durable Water Repellent] Finish - DWR allows fabric to shed moisture and prevents saturation to keep you warmer. DWR also helps repel oils and stains which can affect the fabric's breathability. Clothing with a DWR finish is a must in snowy or wet conditions.
