Ghost Whisperer Packable 800-Fill-Power Down Hooded Jacket

This jacket is incredibly tight in the armpits, and the sleeve opening doesn't seem to scale with larger sizes. I'm 6'1 & 210lbs, i go to the gym but im not bulky - i normally look for a relaxed fit for tops so i generally wear an XL. I ordered this jacket in XL and was shocked by the tightness in the armpits, a result of under-sized sleeve openings at the torso. I exchanged for XXL and the problem was the exact same, except the rest of the garment was now oversized. the materials are premium but obviously not suitably designed/tested for varrying body shapes, especially odd because this is a mid-layer and should accommodate other layers underneath. MHW please please please add ACTUAL PRODUCT MEASUREMENTS to the details of your listing, the current sizing guidelines might be adequate for some but i want to know the ACTUAL chest measurement, sleeve openings, upper arm sleeve circumference, etc. when shopping because i followed the sizing on the site and it failed... twice.
