7x(Air) is a fabric construction technique we invented in which we quilt our WindShear fabric to give added air permeability through thousands of quilting holes. You won't actually feel the windflow; you'll just feel drier.
Alpha construction is the result of totally rethinking the construction of a winter jacket. On the front we've separated the windproof layer from the insulating layer, giving you far greater control over ventilation, and when you're working hardest you can open the external zip to allow airflow to dry the thermal layer. It's hard to imagine until the first time you crest a hill and close the zipper back up and realize you're totally dry. You've never felt anything like it.Features :
