On 50f mornings once my 'furnace' kicks in I'm OK with a single layer (a tad chilly but OK), but the problem is is that it takes a mile or more to get my 'furnace' going good. Should I start with another layer and after a mile or so take a short break to put it away, or 'grin and bear it' and start off cold and tolerate it until I warm up good?
The temperature it affects you is probably different, but my bottom line question:
How do you handle layering changes through the day on the trail?
