I am slowly upgrading my gear, watching for sales and piecing together what I hope to be a set of clothes that will get me from early archery to late whitetail. A few months ago I scooped up a sitka kelvin jacket that is a size large. My intent was to be able to use it for early season as an outer layer on cool mornings or evenings then a mid layer during late. My dilemma is that size large seems to be a "tweener" for me. Would you go for a little big or a little tight?
