"My ‘watershed’ ride in the Gabba came on a day of near perfect conditions – a low cloud blocked most of the daylight, and emitted constant drizzle that turned to rain through the course of this 90 minute ride. The temps hovered between 10-14C degrees and the ride included a climb to 400 meters above sea level, and a 2km descent at speeds around 55-60 kph – so lots of opportunity to test heat management, wind chill, and everything in between.
I prefer to be on the warm side on my rides, so I’d layered up with the Iride Base t-shirt, covered by a Castelli breathable lightly fleeced longsleeve jersey, with the Gabba longsleeve on top. Down below I wore the Polare bibtights, and the Diluvio16 neoprene shoe covers on my feet."
See above quote from Pez Cyling. If I wore that much kit in 10-14 degrees (celsius), I'd be a dehydrated puddle of sweat after 2km. I wore less than that on my commute this morning in -2 degrees of freezing fog.
