Usually, after not riding for atleast a couple of hours, (worse first thing in the morning) I gear up and put my helmet on and instantly I get tight chested. I wouldn't say hard to breathe, but I tend to take a few deep breaths to try and relieve the uncomfortable feeling. And as soon as I start riding, I'm fine, I don't get it at the lights when I'm stopped or whatever, only just after i've lidded up. Anyone else get this? Do you think it's claustrophobia, or maybe I just get a bit anxious before a ride? Just curious is all.
