evo.com | Nike Activewear Jackets > The Nike ACG Therma-FIT ADV Lava Flow Jacket was tested on a canoeing trip through Big Bend National Park, which means it's proven itself against serious cold desert nights and actual adventure conditions. PrimaLoft insulation fights off the chill while that water-repellent finish keeps you dry, and the whole jacket packs into its own internal pocket so you're not carrying dead weight when the day warms up-just clip it to your pack with the ACG carabiner and keep moving.
