BTW Grylls stuff is probably Craghoppers sub brand aimed at the younger end of the market who are more likely to be influenced by Gryll's stunts. Hence the stylised cammo colouring. If you are not in that younger age group then perhaps you should stick to your usual decades old itchy woolen y-fronts.
That's what I do (suitably washed of course).
Berghaus also has a sub-range aimed at the more trend conscious younger market called Ator I think.
And before anyone asks I am going to start going to the gearfreaks anonymous for help very soon just got a few more purchases to make before I get help.
