Sigma Women's Jacket
The Sigma, and its direct men’s equivalent the Vega, remain leading lights in Alpinism. They’re jackets that have been used everywhere from the first ascent of Latok I from the North to Denali’s Cassin Ridge and the hard winter classics of the Alps. Balancing on the fine line between absolute warmth and the minimal packsize that makes the cut on hard routes, they’re critical kit for experienced climbers.
800 fill power European Goose down is strategically distributed through the jacket and held in place by the stitched-through baffle construction, optimising warmth and preventing down migration that can lead to cold spots, particularly in vulnerable areas such as the shoulders, chest and hood. All of our down is minimally treated and DOWN CODEX® approved, meaning it’s sourced through a carefully audited supply chain.
Lightweight and highly water resistant DRILITE® Loft outer fabric allows the down to loft to its full potential, providing maximum warmth while protecting it against melting snow, ice and pouring spindrift. DRILITE® Loft also offers complete wind resistance and excellent breathability, keeping you warm and comfortable even when working hard. This protective outer fabric also extends around the inner hem and the hood lining, protecting you and the jacket inner from moisture ingress in these typically vulnerable areas. Meanwhile, seam-free shoulder panels improve water resistance even when wearing a pack.
The grown-on insulated hood uses our patent-pending Firestorm construction, combining a sewn-through baffle structure with a drop outer fabric to provide an invaluable defence against the elements in serious conditions. Baffle pleats reduce the overall volume without compromising warmth, and a pleated halo baffle around the face offers reassuring warmth and protection against freezing winds and spindrift.
