Walking through Blacks yesterday I spotted a shirt with the Bear Grylls Logo! It seems that he has teamed up with Craghoppers to bring out a range of clothing for outdoor use. Not too much info around yet but I have been impressed with craghoppers kit in the past - I think its called 'the survival range'
