Ever find yourself a bit chilly during the summer months, and wishing you had some light insulation?  The Atom SL Hoody from Arc'Teryx was designed especially for those circumstances when the weather changes unexpectedly or you're changing elevation and you need a lightweight but slightly insulating layer that's suitable for milder conditions.  This jacket's warmth compares with that of a light fleece, without the extra weight.  The Atom SL Hoody is the ideal lightweight jacket both on its own or under other layers.
