Design PhilosophyThe Pakajak is a no-frills windproof shell that does as it says in the title - packs down into a tiny stuff sack (included) so you can carry it with you all the time, ensuring it is there for when you need that extra bit of protection to keep you comfortable. Weather Ready ProtectionThe jacket is constructed using a lightweight, windproof ripstop melange fabric with a PFC free DWR treatment. The underarms use an open mesh to improve ventilation and comfort.Considered SafetyReflective trims on the front, rear and sleeves increase your visibility to other road users. The high-viz yellow option adds an additional layer of safety in low light conditions.
