The Exofficio Storm Logic Jacket is compressible and travel friendly. Unlike other bulky insulated jackets, the Storm Logic Jacket rolls up into a built-in stuff sack and transforms into a neck pillow or lumbar support. It also packs away easily so you have warmth wherever you roam. The Primaloft® Sport synthetic insulation keeps you toasty even if it gets wet, and the soft ripstop nylon is treated with a Durable Water Repellent (DWR) to protect against the elements. A fully featured internal Travel Pocket System keeps all your items organized, from glasses to passport.
