I once saw Optimus Prime wearing the 60% cotton 40% polyester Transformers Autobot Black Sleep Pants. The weird thing is...he was in his truck form! I'm not really quite sure what was happening and I hadn't slept in several days. However, I got the super comfortable Transformers Autobot Black Sleep Pants which feature red/white/blue gradient Autobot symbol and I fell asleep immediately! They are just too nice - my only gripe is now Starscream and Megatron won't leave me alone. Suppose that is the price for style.
