The M2 is a burly pack designed for the modern alpinist. The simple construction from 600D Ripstop Polyester and the lack of extraneous bells and whistles make the pack extremely tough and give it a low profile which is noticeable during light and fast ascents. Technical features include mesh pockets on the waist and shoulder straps, 2 large mesh pockets on the sides for easy access to layers and other essentials, an external helmet carrying system that hides away when not in use, 2 ice axe carriers designed for use with modern tools, holders for trekking pole, lateral ski holders, and rope carrying straps. Soft 3D mesh padding on the back panel, shoulder straps and waist belt provide exceptional comfort and breathability. Exclusive EZ OP buckles on the waist belt and chest strap can be opened with one hand; a feature that is especially useful when wearing gloves.
