Lifaloft Full Zip Insulator 3/ M Black

These insulation shorts from Helly Hansen make it easy to stay warm using the layer-on-layer principle. The shorts can be opened with zippers on each side to easily put them on and take them off if necessary, either on top of your regular trousers or under a pair of shell trousers. The LifaLoft insulation is 20% lighter than normal insulation without losing its warming properties, making the shorts lightweight and easy to pack.
