This is such a great product. The quality in craftsmanship is obvious from the second you pick the jacket up. It has some weight to it, but not too much. Everything about it is well-thought out just like the description of the item discusses. If you’re wondering which size to get, hopefully this helps…I’m 5’ 11” and weigh around 210 lbs. I have broad shoulders and an athletic build. I actually bought L and XL and find that the size L is a better fit for me. I think the only reason I say this is because of the stretchy type of fabric this is made with. The L in most other fabrics would not work because of not enough room in shoulders and lats (especially when leaning over—think getting kids into carseats, picking up after dogs while walking, etc). However, this jacket moves with you and gives where/when you need it to. It’s nice to have a jacket that fits well in chest and stomach area without having to buy a size up just to accommodate shoulders and then having it fit you like a paper bag in the mid-section. The XL also fits very well, but there is a bit extra room in the chest/mid section that makes it not as comfy as the L. Otherwise—it also fits well. So if you’re in that ball park of height weight I mentioned above but have a bigger chest or stomach—XL is probably your ticket.
