I couldn’t figure out the differences between these two jackets, based on my internet skills, I think this one may have 700 fill down, since it’s the older model. However I’m not sure, so I ended up getting both. I can always give the other jacket as a gift. From my past experience with Craghopper/Bear Grylls Clothing. They go by European sizing. I normally wear a Large, but I fit in XL for this company. I’m 6’2 and 200lbs. Great deal for a down jacket, plus they have a lifetime warranty.
