Any Roman male would use only woven wool clothes. Thinner fabrics, like linen or expensive imported silk or cotton were normally used only by women. Men who used them were derided as effeminate.
Moreover, knitted wool is mostly suitable only for undergarments, as it does not offer enough protection against water and wind.
Knitting provided more comfortable clothing, but it was not a necessity. There is no surprise in its late development.
