Okay, following up my post last week about wanting to take a traditional or 'minimalist' approach to a long trek I have planned, I need to get myself sorted with what I think is the most important part of clothing; the outerwear. I've yet to order a Bison bush shirt and see for myself so I'm just using other people's interpretations via reviews. I'm thinking of using a merino wool base layer, with a bison bush shirt on top, but what to do about the outer? I'm staying away from technical garments because I've splashed out a lot of cash in the past for Goretex and I loathed everything about it. I'm thinking about either wearing a Swanndri Bush Shirt as my outer layer, or using a synthetic poncho over the Bison shirt, but I know I'd find the poncho terribly clammy and sweaty, and not to mention even with a belt it will be flapping like a flag in the wind when I'm venturing onto higher land. At the same time, at points in the trip I could be without drying clothes for many days, so I'm finding it hard to find the right solution. Any suggestions?
