Offering an exceptional warmth to weight ratio ideal for cold mountain days, this fleece jacket combines Polartec® High Loft™ wool blend with our Merino and synthetic fusion fabric. Maximising the benefits of superfine Merino fibres and fast drying synthetic, the Syncrino HL is built for cold environments. Perfect for high energy mountain activities in winter weather including climbing, mountaineering and fast hiking, the Syncrino HL is highly efficient at regulating your temperature. This fleece jacket is made from a combination of materials, body mapped according to heat output. The main torso of the jacket is formed from Polartec® High Loft™ wool blend, a feathery soft combination of Merino and synthetic fibres with extended yarns that create large air pockets to trap more heat. The stretch side panels are made from a smooth face Merino and synthetic material that works to wick away moisture, drying quickly to increase comfort in changeable mountain environments. Highly compressible, breathable and with the anti-odour benefits of Merino wool, the Syncrino HL is a seriously technical layer. It has a fleece lined collar for additional warmth, a tough and practical full length YKK® VISLON® ® front zip, and a useful zipped chest pocket. Adapting to ever-shifting conditions, the Syncrino HL works hard to keep you warm and dry through both intense climbs and static belays, ideal for any cold weather adventure.
