A hyper-modern lightweight down jacket the Gramicci x Nanga UL Portable Down Zip Parka is a superlative piece, produced in a micro-ripstop nylon, with a neat fitting insulated hood. The down used is an extremely high-grade of white goose down, sourced from Poland, with a prodigious 860 fill power. Despite its minimalist design keeping weight to an absolute minimum, Nangas expertise has made room for a chest pocket, hand pockets and an internal stash pocket, which the jacket also packs into.
