I live just outside of Chicago, so our fall weather can really swing up and down the spectrum. Last weekend, it was in the high 40's/low 50's when we headed out...but expected to get to 70. Since we usually try to be back home by 12noon, I opted for my Descente knickers and long-sleeve jersey. I was a tad bit chilled for the first 1/2 hour or so, but after that, was quite comfortable.

Yesterday, it was in the low 60's starting out, but drizzling. Again, I wore my knickers (PI this time), a lightweight merino wool base and a windbreaker type cycling jacket. Was a bit warm initially, but once I was sufficiently WET from the steady rain...I was FREEZING for the remainder of the ride. Yeah, my jacket was NOT water-resistant, so the merino wool top got soaked and didn't do much in the way of regulating my temperature.

Today it was high 50's when we started with an expected high of near 80. I had plans of shooting for 100 miles today, so would be out a bit longer. I opted for shorts, short-sleeved jersey with arm warmers (which I removed 40 miles into the ride), and was comfortable.

I love knickers. I have 4 pairs - Shebeest, Descente, PI, and PI Thermal. For tights, I rotate between 4 pairs - PI Thermal, Sugoi Sub-Zero, Performance Tri-Flex, and Under Armour (all unpadded because I prefer to wear my favorite shorts underneath). I do also have 1 pair of padded tights that I recently bought from Sierra Trading Post - Descente ColdOut Tights...couldn't pass them up for the price. I have yet to try them out.
