On second examination the Gore jersey isn't extremely tight considering the stretch but I feel it a bit when I breathe. Fits alright in the chest and would fit well in the lower torso if I lost a couple pounds. I found the culprit to my most major discomfort. There is a tag sewn into the seam running up the left hand side that is really uncomfortable. I could snip it off but what's sewn in would be left on the seam and it's scratchy.
Kinda torn on this one now but I'll probably return it. I might be able to remove the label without damaging the seam if I'm careful but I'd rather not ruin it trying. The PI is definitely going back though. I measured it armpit to armpit and it's only 16 inches! Now, my math isn't so hot but last I checked 16" x 2 = 32" and the material isn't that stretchy. No wonder it's so snug. They recommend this jersey for up to a 37" inch chest and it's supposed to be semi-form fit. I don't think so...
