Icepeak says about the Dorr
Softshell for shielding from the elements or stretch for maximising the freedom of movement? You don't have to choose any longer. The front of the Icepeak Dorr outdoor trousers is made of a softshell material that protects from water and nasty winds, while the Thermostretch jersey on the back provides warmth and stretches as you move. Thanks to the slim fit, you can easily add layers on top when you stop for a break or if the temperature takes a plunge. There are two zipped front pockets, and the higher back waist provides coverage for the lower back.
