Thick material hingers range of motion
This jacket fits very well, is warm, and allows full range of motion in my arms and should otherwise be a great jacket to layer up during cold morning workouts. The only problem with this jacket is that the thick material bunches up when you curl up your waist. lighter material hoodies I've owned tend to accomodate this range of motion well but this jacket bunches up too much and can hinder doing crunches, etc.
