Surmount Primaloft jacket is one of those products that you'd think you don't need, but once you've tried one, it is difficult to imagine not owning one. The already once revolutionary Primaloft® insulation has now become even more impressive with the new Air Gel Cross Core technology; 40g/sqm measure same loft values as the previous thicker 60g/sqm. The heat insulating properties from such a thin padded product is difficult to imagine, needless to say impressive in practical use. Wear Surmount waterproof products outside the series of Primaloft insulation for full weather protection and comfort.
