Usually I wear my summer kit with thermal arm warmers and thermal knee warmers in the upper 50s. Moving into the lower 50s, I swap the knee warmers for thermal leg warmers. If lower 50s are the high temps— i.e. if it’s in the 40s at the start of the ride— I use thermal bib shorts. On top, it’s either the aforementioned thermal arm warmers with summer jersey or a long sleeved base layer under summer jersey with thermal bib shorts.

I really like thermal bib shorts and tights, because that extra warmth across the lower belly and waist really does a lot to keep me warm and comfortable.
