For spring or fall days, when you know you're going to get caught in a rain storm, Sportful's Hot Pack 5 Donna jacket keeps you dry. And, if you're worried about getting chilled, it's windproof to keep the cool air from rushing by your skin. The Hot Pack 5 was sewn from Schoeller NanoSphere fabric. This fabric effectively maximizes stretch and breathability while minimizing wind and water penetration. The result is a lightweight jacket ideal for wet spring days. The Hot Pack 5 is cut to fit best while riding and to this end it features an extra long tail and lengthened arms. The cuffs have a thumb hole to keep water from creeping up your wrists. An internal compression stuff sack holds the jacket when the sun begins to shine, but if it doesn't, and you end up riding home in the dark, Sportful has added reflective accents for low light visibility. The Sportful Hot Pack 5 Donna Jacket Women's is available in sizes X Small to XX Large and in the colors White and Black.
