A jacket that works well while you ride and while you hike is ideal. The Sugoi Firewall 180 Jacket keeps you protected from the elements while you are; in the saddle, on the trail, or running through the city on a windy day, when the temperature isn't at an all time low. The wind and water resistant properties of the Firewall 180 fabric, for which this jacket is named, are what make it a great winter piece for cycling, running, and cross country skiing when the weight and intensity of the Firewall 260 isn't needed. The Firewall also has optimal breathability and and thermal regulation properties. While you are busy trying to put the miles in, your jacket is working to keep your temperature regulated and your skin dry. Functional stretch in the sides of the fabric give you an adequate range of motion for your various outdoor activities. For areas of the jacket that are not as wind prone, super-lightweight Sugio Helium fabric is used for it's high wind and water repellency, adding to the protection of the Firewall 180. Ultra-fine denier yarn is used in a ripstop pattern so you can be as hard on your clothing as you are on your run and not worry about the fabric giving out.Cut in a slender fit, the Firewall 180 also comes with dual adjustable shockcords, accessible from inside the front pockets, so you can pull the hem closer to your body to block out cool air. For ventilation through the bottom of the jacket, simply reverse the process and get air flowing as you mash up hills. A full length zipper makes cooling off during intense activity and blocking out cool air easier. Because weather is unpredictable, a stow away good in the collar has you covered when a sudden down pour adds moisture to your ride. Two welded zip pockets with reflective piping on the front keep cold air from sneaking in at the seams and your phone, keys, and nutrition secure. Reflective 3M Scotchlite reflective accents add visibility for early dawn and dusk activities. The Sugoi Firewall 180 Jacket is available in Black/Black, Gunmetal/ Terracotta, and Amethyst/Black. It comes in X-Small through X-Large sizes.
