They are thin definitely for warm weather riding although I do like the fit.
Bibs size runs true Base layer I like a little bigger But love their stuff
Quick Wick & light
Possibly one of my favourite Giordana pieces that I own. It is very light, and super breathable. It doesn't ever shrink or loosen up, and it doesn't really hold onto odour. I use mine in more than just cycling and I found that only after the third or fourth time I wear it, I have to actually wash it. It also instantly dries and never holds sweat in.
