Like all Norse Project products their descriptions are no nonsense, to the point and wonderfully clean...

"The 3L Waterproof Shell Jacket is a waterproof hooded jacket. Featuring asymmetric front closure and neck gusset opening. Finished with side entry pockets, and moulded velcro cuff trims make adjustment secure and easy. It is compatible with all Pertex midlayer styles offering optional four-season functionality."

You can't complain about that, so let's just add that, it's made using 100% GORE-TEX polyester and 75 denier recycled face fabric, it has been treated with a Durable Water Repellant (D.W.R.) coating while remaining breathable in all conditions. If there's just one 3 layer, waterproof, GORE-TEX shell jacket compatible with all Pertex midlayers you want this season, make it this one.
