So I'm in need of a new winter jacket and was thinking about picking up a Dakota jacket from Marks. However, I recently bought an Arcteryx Beta SL shell jacket and I really like it. So I got to thinking about checking out some of their heavier duty wear. The problem I'm having is whether I can justify spending the extra $500 on a jacket like the Fission SV compared to a Dakota Hyper-Dri HD2. Apart from the name, is it really worth the extra cost? And are there any other decent comparable jackets out there? I'm looking for a snowboarding style jacket, not a stylish overcoat.
