Re-designed for this winter, the Xenon X jacket now has Primaloft Gold Insulation Active giving the wearer plenty of warmth even on horrible damp days when standing about belaying on windy crags and during other outdoor adventures where the weather can be a bit tricky. It has an under helmet Lycra bound hood with a useful two way Ykk Vislon front zip with insulated baffled and chin guard. It comes with two Ykk zipped hand warmer pockets and a internal one which doubles as a stuff sack too. Elasticated cuffs and hem draw cord help to keep the heat inside and the Pertex Quantum outer fabric is light, strong but soft allowing plenty of room for lofting of the Primaloft insulation. Its really breathable and eliminates cold spots, this Xenon X is versatile and is a fantastic award winning jacket from the mountain experts.
