The Patagonia Men's Microdini 1/2 Zip Pullover is a lightweight fleece that provides everyday warmth and comfort. It has a half-zip with standup collar for warmth and set-in sleeves that provide you with chafe-free comfort. There's then a handy zippered pocket on the chest for storing small items or essentials. As always with Patagonia, this jumper is Fairtrade certified sewn and 68% of the fabrics they've used this season have been made from recycled materials.
