Our seven-pocket ultra jersey is built from a merino wool blend for naturally moisture-wicking insulation, with a windproof chest panel for deep-winter warmth. Capacity - A spacious seven-pocket design ensures you'll have plenty of room to bring along all the ultra-distance essentials. Fit - With a slim--but not overly snug--fit, the Odyssey Windblock Jersey is ideal for long days on the saddle where comfort is a key priority. Temperature - The Odyssey Windblock Merino Jersey combines a warm, breathable wool fabric with wind-stopping chest panels to fight the chill of breezy autumn and winter riding. Thermo - Our merino-blended fabric balances warmth and breathability while ripstop chest panels stop the breeze from chilling your core. Visibility - Reflective details on the backside of the jersey increase rider visibility on after-dark excursions.
