L.L.Bean Pathfinder Gore-Tex Shell Jacket vs Arc'teryx Trino SL

My old Pathfinder died after many years of service and I wanted to replace it with its clone. I'm a 5' 10" tall woman, so LL Bean's women's sizes are too small. My old Pathfinder was a men's S and fit well through the shoulders and hips. The new one is smaller, despite being sold as the same size, and is now too small for me around the hips

Fit – I’m 5’ 9” and 140lbs, and quite slim and based on the sizing guide I went with the Medium. A small would have been a better option and would have still allowed for a base and a heavy fleece or merino mid layer for when it’s -10 and below. It really is a trim fit; a next-to-skin fit would be more ideal for performance XC skiing.
