I'm not a fan of DHB products - have tried several items and always disappointed. Not covering those legs in that weather is actually a bit stupid and asking for muscle strains and bad knees!
If you're referring to me, that's a cyclocross race, and I am at 95% of HRmax, pretty much the whole race. Not much chance of any part of me being cold
Interestingly, until quite recently UCI regulations required cyclocross racers to wear shorts to races. Now longs are allowed, but it's a personal preference thing. I warm up in longs, but race in shorts.
If you're not referring to me then soz
