Aerogel is a nearly weightless super-insulator, used by NASA in satellites and other space technology. A commercial version, Primaloft Gold Aerogel, first hit the outdoor gear market in 2017 as a synthetic and ultra-warm insulation. L.L.Bean had exclusive rights to use it during its first year of release, notably in the company’s Packaway Jacket ($169, hooded $189;, although now it is commonly used by many outdoor brands. This season L.L. Bean is offering an upgraded version that includes a waterproof outer shell, multiple fleece-lined pockets, and a longer length for more coverage.
