I don't have any hooded ones myself, and the ones I have tried on always seem restrictive (too tight etc). You can just Google "hooded base layer", or try something with a high collar and then use your choice of Buff. It'll be better than a base layer with a hood. Synthetic moves moisture better but will smell after one use and need washing / merino is better for slower riding or multi-day trips or stop/start rides. Icebreaker stuff is a weird fit, so would avoid.
