The Atom LT jacket is lightweight, warm, breathable and perfectly patterned to allow mobility in any mountain sport, being highly recommended for activities that involve a lot of arm movement such as climbing, ice climbing, snowshoeing and ski touring or in other mainly aerobic situations. It can be used as a mid-layer in very cold conditions but is also a great single layer for use in intense activity or for warmth when winter conditions require it. Comparatively, its insulation is comparable to that of an average fleece but with significantly less weight and far superior compactness.
