686 Smarty Arctic Jacket: The arctic life in which the 686 Smarty Arctic Jacket lives is filled with warmth and comfort. That sounds like a contradiction, but when you outfit yourself with INFIDRY 15 technology and the ability to create 3 jackets out of 1 you begin to see the bigger picture; that’s what the 686 Smarty line is all about. The warmth of its 250g removable fleece quilted Smarty hoody liner combined with the fully taped seams of 100% poly chambray window pane fabric make this arctic crusader a powerful ally when you need to adapt on the fly. The outershell and liner create a triumphant union to combat the worst weather imaginable. When that weather calms you can wear the two separately… 3-in-1; the Smarty way and the smart way.
