Ideal for summer in the mountains, the mens full-zip lightweight fleece (OL) has a compact packed size, so you can keep it in your rucksack, on standby for when it gets cooler, higher up the hill, or when its time for a quick rest break. This lightweight summer fleece is a great piece of kit for all your trips. Made of NANUK 100 ECOSPHERE fleece, it provides the light insulation required for warm weather or energetic activities. You can also combine the fleece with a compatible shell jacket using the system zip (length: short).
