This is Rab’s lightest synthetic insulated pullon; offering warmth & weather protection for all winter mountain activities. This phenomenally lightweight pull-on is filled with Primaloft insulation & uses Pertex Quantum fabrics to ensure it will pack down teeny tiny & still offer warmth & weather protection when required. Primaloft One is a siliconised synthetic insulation fibre that resists compression, is lightweight & absorbs virtually no water making it extremely weather resistant & extremely quick drying. Combine this amazing filling with the lightest Pertex Quantum fabrics & you have an incredibly lightweight yet warm jacket. Because of its fantastic weather resistance the Xenon X Pullon can be pulled on over other layers to reduce chilling when you stop, or it can be used as part of an efficient layering system for more active pursuits in extreme conditions. When not required the Xenon X Pullon will stuff into its own chest pocket & become virtually unnoticeable in your pack. The Xenon X Pullon has a high insulated & soft lined collar & plenty of zipped pockets to keep your essentials safe. This is a super lightweight, warm pullon for use in cold wet conditions, making it absolutely perfect for UK winter mountain activities. 60 g/m² Primaloft One synthetic insulation High insulated & soft lined collar YKK front zip with internal insulated baffle & chin guard YKK zipped hand warmer pockets YKK zipped chest pocket which doubles as an integrated stuff sack Elasticated cuffs Hem drawcord Slim fit
