When is cold actually cold? Arguably, it's a very subjective answer, and one that, when reviewing the Universal Colours Women's Mono Bib Tights, I pondered a lot.

For many people in the northern hemisphere, the end of August marks the end of summer. For others, it's Meteorological autumn, which begins on September 1st, or you could choose the astronomical autumn, starting on September 22nd.

This level of ambiguity is even more apparent when applied to temperature. Cold in summer is very different from cold in winter, and it's often debated when it is cold enough to turn the heating on.
