The other day and 5C, shorts.
At about 3C downhill I will start to feel some pain.....................that soon disappears on the first uphill
We are all different, through age means I feel colder sooner with inactivity, plus the meds I am on mean cold hands and even lower arms........thats been like that for several years, but I am good as long as I exert myself.
My hands used to sweat all year round.........not so much today.
