Much like jeggings, treggings is a portmanteau of trousers and leggings.
[1] Treggings fit just like leggings, but are made out of a thicker fabric.
A British school decided to send 60 students showing up in treggings home on the reason that the clothing was too tight to be worn as trousers.
[2] The tregging is very popular among young women as an alternative to stockings or trousers.
