Strange sizing for a Pearl Izumi jacket.  I'm 6'0" with a 44 chest and 16.5" neck.  In XL, this jacket was snug in the chest and too small in the neck.  The arms however, were long and baggy.  I returned it.  I may reorder in XXL however, I'm concerned the fit and length of the arms will be even worse.

The fabric is very thin.
