+1 on the heated grips!
Tried heated gloves with my previous bike, but the wiring was always a pain to deal with.
Last two long weekend bike trips happened to coincide with cold fronts where the temps didn't get out of the mid 50s on one trip and started in upper 40s with high in low 60s on the other (hey that is cold for Texas). Not super cold but would have been very chilly without proper layering and the heated grips, especially riding for 8+ hours a day.
I had my grips installed last year, but since then I changed out my bars on my own and would say I could have installed the grips easily myself.
