We are thinking of buying the T101 front extension for out Venanas II 650xl TC. I know this particular extension is polyester, but I was wondering if there is a TC version of this. If not will this fit our tent. Thanks in advance.

Unfortunately not, Vango only manufactures a polyester Front Awning extension for the tent as the price of it in Polycotton was cost-effective. The Polyester one is ideal as it still offers the space you need and is a very similar colour to the polycotton tent.
