Rising up from the balmy warmth of the valley floor pedalling to the rarefied air of the alpine pass you'll welcome added wind protection on the long descent back down. The Northwoods is ideal as it's extremely wind resistant, a full front zip and elasticized cuffs and hem sealing tightly against the wind.
