The Magma jacket is a fully waterproof outer layer down garment

It uses eVENT fabric, believed to be the most breathable available. The high performance of this fabric is not compromised by any stitching, with the down being held in place by baffles bonded to the inside of the eVent membrane.

There is 225g of Polish white goose down to provide sufficient insulation for alpine climbing for most of the year.

There is a removable hood with a wired peak and two generous pockets sized to swallow screws, mitts and guide books.

The Riri zips are more water resistant and durable than conventional PU-covered coil zips.
