| "I used to be Robin Hood at the Tales of Robin Hood (a former Nottingham tourist attraction)… so I worked in tights day in and day out and I know the value of properly warm tights on a cold day," he said. | "I used to be Robin Hood at the Tales of Robin Hood (a former Nottingham tourist attraction)… so I worked in tights day in and day out and I know the value of properly warm tights on a cold day," he said. |
| He said the formula, designed after being approached by BBC Radio Nottingham and which uses the sigmoid curve to create a scale to calculate the denier or density of fibre needed, will work across the UK as it depends on the local weather conditions. | |
| "I used the Sigmoid formula here because it lets you have very little change at the extremes (so if it's hot you want thin tights and if it is cold you want thick tights) and lots of change in the middle (from -5 to 20 degrees)," he said. | "I used the Sigmoid formula here because it lets you have very little change at the extremes (so if it's hot you want thin tights and if it is cold you want thick tights) and lots of change in the middle (from -5 to 20 degrees)," he said. |

| The formula can be altered to allow for warmer southerly winds and colder northerly winds by using kilometres per hour for colder winds and miles per hour for warmer ones, he said. | The formula can be altered to allow for warmer southerly winds and colder northerly winds by using kilometres per hour for colder winds and miles per hour for warmer ones, he said. |
