The insulated FLEX jacket uses high quality, extra thick, yet flexible neoprene material to insulate your FLEX/FLEX+ from the worst ambient conditions like a hot garage or cold basement. Each custom designed, hand stitched (in the USA) jacket is custom tailored to fit the FLEX. The jacket was designed by a former Lululemon designer because if your going to cover up shiny stainless steel it better look amazing!
