Days in the alpine and evenings in bivies call for the Rab Women's Snowpack Down Jacket. With a breathable microporous waterproof coating, this jacket's Pertex Shield shell sheds snow spray and rainfall to protect the light and lofty 750 fill down insulation. Rab coated the down with Nikwax to help the insulation retain its loft even if it somehow gets wet. The Snowpack Down Jacket also features a helmet compatible hood with a wired peak that stays out of sight during belays. There are multiple adjustments at the hood, hem, and cuffs to seal out bad weather. The A line pockets are accessible even with a backpack or harness on, and the internal security pocket protects valuables from the elements.
