Norrona's Trollveggen Superlight Down800 Hooded Jacket battles the weather while we battle the climb. The tightly woven fabric puts the lofty fill on lockdown, takes the force out of bone-chilling winds, and snubs spindrift, while the adjustable hood extends our armor against the alpine's wrath. Packed with highly compressible down, this puffy turns up the heat without burdening the scale.
