So, I am needing a bit of help with my layering system.
What I am thinking about doing is using a T base layer. Then getting something like the Patagonia Cap 4 zip neck and using that and my wind shirt for when it is cool out. Adding my R2 when I stop to hopefully take me down to around 25F and if it is raining, a rain jacket. Beyond that a hooded down jacket. I know I am relying a lot on the T-Cap 4-wind jacket-R2-rain jacket for the chilly temps but I really don’t want to buy a synthetic. Any thoughts? MH Ghost Whisperer?
I have some Wind Pro OR gloves, 300PL fleece Mitts, WPB shells and Primaloft mitts so I am not so worried about that. I also have an OR Wind Pro hat and balaclava which keep my head pretty warm down to about the 25F line.
I wish there was a better layering system for you legs. I can wear the Ex Officio boxer briefs along with the REI Sahara pants and put some side zip rain pants on over them but it is hard to put the fleece pants on in this situation and I am really not a fan of the side zip synthetic and down insulation pants but I should probably make myself be.
