Can anyone tell me what impact the tightness of clothing has on temperature regulation and general sweatiness whilst cycling (or any other similarly intense exercise)?
Assuming that both sizes are equally comfortable to wear, and leaving aerodynamics, appearance, suitability for layering during winter and everything else aside, will a larger jacket prevent overheating and/or breathe better than a smaller version of the same jacket (assuming identical environmental conditions etc.)?
I understand how a tight base layer made out of a suitable wicking fabric helps keep you dry, but if a jacket is not skintight, then presumably it can't help moderate temperature or deal with unwanted moisture in the same sort of way. In which case, wouldn't a loose jacket be better to increase airflow?
Any thoughts much appreciated, as I have failed to turn up anything reliable through google.

Why would you want a loose flappy jacket letting in rain wind etc?
I believe that loose does have advantages when it comes to heat, think about why Bedouin where loose dark clothing in the desert?
But it doesn't get that hot in the UK, aerodynamics matter when your traveling at 20mph. Just get close fitting kit that breathes well and don't overdress.
The larger jacket wouldn't exactly be 'loose and flappy.'Certainly not so loose and flappy that it would cause any very serious aerodynamic problems. Hmmm. In which case, perhaps it wouldn't make much difference to temperature regulation and breathability either.
I find for shirts is the material is breathable tight is better. The tightness allows the sweat to transfer to the clothing and it can just move though the shirt and your'll lose heat quicker.
If the material isnt breathable (like many "official" football shirts) then loose tends to be better as it lets the air circulate underneath so that the sweat can evaporate.
I started wearing baselayers even in the summer last year, actualy makes things less sweaty usualy! Get's stinking hot through if you can't unzip your jersey.
Just get the tightest you can comfortably wear, if you want to be cooler, why are you wearing the jacket?
If you're wearing a waterproof you'll sweat like a bastard, end of - as my dear old nan used to say
Vents are good, flappiness isn't helpful IMO

That's what I would have thought. After all, don't breathable fabrics depend on their being a difference in relative humidity between the inside and outside of the fabric? I thought this was why goretex was supposed to be less breathable when it was actually raining. But as far as jackets are concerned, isn't 'breathable fabric + slightly more room' the ideal combination?
