Product details:

In howling winds, take refuge in this light layer. The fabric has low air-permeability to shut out heat-stealing wind. When packed into the integrated stuff sack, it takes up the same amount of space as a couple of chocolate bars, so it's minimalist enough for any trip in the mountains. Made of windproof Hyperlite nylon that has great abrasion-resistance. Elasticated hood has a rear adjustment to prevent flapping in strong winds. YKK front zip has an internal storm flap. 2 front zippered pockets warm chilly hands or hold small items. Elasticated cuffs and drawcord hem let you adjust the fit. Reflective hits. Fits inside the integrated internal stuff sack. Regular fit.
