I am 5"10 175lbs and I got a medium in this jacket. It fits totally different than the marmot zion did. The sleeves on this jacket are perfect for me but the arm pit area is right. The Neck is also kinda of tight when zipped all the way up and hood down. The marmot was the opposite. The sleeves were way too long but the rest fit a little better. The put zips and the taped seams feel like small golf balls under the arm pit. anyone know if these are truly different between and M and L?
