The temperature ranges on RW are completely ridiculous.
They say shorts are only good for 65+.
They say you need long sleeves when it's in the fifties.
Even the heaviest winter tights are only rated down just below freezing.
Take it from a person who lives in a place where it gets seriously cold. Don't pay attention to this crap. A jacket that RW rates for 50-65 degrees is probably a good jacket for temps in the 20s.
The temperature rangers from RW must not account for any vigorous activity include running. They must be based on someone standing still or at most walking slowly. If I were to ever run at a 9:30 pace during cold weather I would wear a heavier base layer than for my normal run at 7 to 7:45 pace. I think someone's pace and body fat percentage would need to factor into the temperature range they find acceptable for any clothing.
I just looked at some heavier cloth tops and jackets at my local UA and Nike Outlet stores and decided all would be too warm for me for most of my running that normally is from 15 to 30 degrees F. I wear a polyester shell jacket (no lining) and UA cold gear long sleeve top when below 30 degrees. Much below 15 I may add a very thin low percentage merino wool blend long sleeve top.
Well at least Nike is trying.
They get an A for effort.
