This is really a great one. I saw this Nike and had a feeling it needed to be a bit puffier, and was right!! The shell is a silky smooth nylon taffeta and the many different compartments puffed up just perfectly with the 850 fill. The jacket is a size M, but started out very oversized so it actually still fits like an XL. It cinches at the hem and the waist for a snugger fit. The measurements are as follows.
 
Chest: 26” flat pit to pit
Shoulders: 22”
Length: 28:
Sleeve: 31” collar to cuff
