The Xiom is a new addition to Rabs range of waterproof clothing for this season; they are made from the superb Pertex Shield+ fabric that is completely waterproof & highly breathable. The Xiom pants feature YKK Aquaguard three quarter zips to make it easy to get them on with boots on & you can open the zip from the top to increase ventilation. As usual you get the superb Rab design & cut allowing a full range of movement from the articulated knees & the fabric itself has a degree of stretch making them very comfortable to wear. An elasticated & drawcord waistband keeps them firmly in place & there is even a hem drawcord if you want to seal them around the top of your boots. Pertex Shield+ fabric is soft & supple & uses a hydrophillic membrane to provide high levels of breathability & complete waterproofing. The Xioms are made with a three layer construction to ensure strength & durability, essential when you are regularly pulling them on over your boots.
