Here are som on it.

From this site http://www.corinnedennis.co.uk/fabrics/
Roubaix (85% Nylon / 15% Lycra)
This is a close fitting, thermal stretch fabric, with a soft brushed lining. Roubaix is extremely warm, and it's high wicking properties help to maintain a comfortable microclimate close to the body. This reduces both chilling and overheating: a risk factor for dehydration.

Fleecy on the inside so it's warmer than regular lycra.
