What is the Norvan SL Jacket?
Arc'teryx's Norvan SL is the pinnacle of mountain running jackets. It's their lightest, most breathable and most packable shell to date thanks to their ShakeDry technology.
What is the Novan SL made of?
The Norvan SL is made using ShakeDry. What is ShakeDry? When constructing a 'normal' shell jacket, you have an inner fabric, then a membrane, then an outer fabric (or face fabric). The inner and outer fabrics sandwich the membrane inside so it's fully protected against abrasion and general wear and tear. However, running jackets aren't designed to be forced against jagged rocks and across rainforests, therefore the outer fabric is simply a barrier making it harder for your sweat to escape. ShakeDry technology eliminates the need for a face fabric altogether, meaning this unbelievably breathable jacket weighs less than your phone. This also exponentially increases the breathability of the Norvan, as your sweat is pushed out by the membrane into the air rather than into the face fabric.
You may be thinking that without a face fabric, the Norvan sacrifices on protection, however, Arc'teryx are ready to prove you wrong. The Norvan SL uses a Gore-Tex membrane, meaning it's fully waterproof, fully windproof and durable enough for a range of running uses.
What are the features?
Moving onto the features of the jacket, you're given a lightweight, fitted hood with an elasticated brim which can be packed down and stowed in the collar of the jacket in a snap. A watertight front zip keeps the water out, while shaped and elasticated cuffs prevent cold wind blowing up your sleeves. An elasticated hem is also supplied to prevent mud and water flicking up from your shoes up your back.
How does the Norvan SL fit?
The Norvan SL fits into Arcteryx's 'Trim Fit' fit block, which means it is designed to sit snug to your body with room for a layer underneath but doesn't have lots of excess material that will flap around in the wind.
Where does the Norvan SL fit in the layering system?
The Norvan SL is primarily designed as an outer shell, more commonly referred to as a hard shell; which means it works well to protect you from strong winds on cold days, right up to torrential downpours.
