The north face bolt polartec hdy

The ideal first layer for climbing and mountaineering expeditions, the Bolt Polartec jacket gives you the protection you need to face the cold. Thanks to its high-density heat-retaining fibres, the Polartec fleece fabric is incredibly warm and lightweight. But it doesn't weigh you down or make you overheat; it's incredibly compressible and quick-drying, so you can regulate your body temperature even when wearing a heavy backpack or waterproof outdoor jacket.
