LAST EDITED ON Apr-28-12 AT 07:30PM (MST)[p]I have Kelty,Marmot,and Cabellas Trekker bags.I'm same size,lighter,big shoulders.All have enough room for me.I get the tall sizes on most things. Depends on how you'll use it. Go to a REI,any backpacking store and ask to check them out,get in it,roll around.I wound up buying two bags in one store.Clearance sale. But I found what works,then bought from Cabellas,CampMor,and REI too. I have 5 different bags for different uses and temps,never spent $200 on any.
