The Lowe Alpine Grid Pull-on, as the name suggests the fleece pile is in a grid construction. This offers an increased surface area to enhance insulation & breathability with a reduced weight compared to standard fleece. This Grid Pull on is a superb mid layer thanks to the enhanced breathability making it particularly suited to faster paced activities. The Polyester fabric absorbs little moisture & therefore dries very quickly. However if you just want a nice lightweight & warm fleece pullover for slobbing about in the Grid Pull On looks a bit different from the millions of other fleece pullovers out there.
