Arm warmers instead of a long sleeve jersey
Arm warmers are the most flexible solution for changeable days. Pull them over the short sleeve jersey in the morning, roll them down at noon, and put them in the jersey pocket. A long sleeve jersey, in contrast, stays on all day.
The transition to the sleeve is important. A silicone band at the top hem prevents slipping. The arm warmers should go under the jersey sleeve, not over it. Otherwise a cold spot appears at the seam.
