My partner and I are going to hike the GR10 / (maybe some HRP) starting in early June and finishing sometime late July. I'm not sure about how warm to pack for the upper body? Right now I planned to bring:
2 thin wool t-shirts
capaline 4 half zip
wind jacket
rainshadow raincoat
WM flight Jacket
my partner (who gets cold easy)is bringing
some wool t-shirts
icebreaker 260 half zip
wind jacket
raincoat
WM flight vest
R2 jacket
Is this just a bad idea to rely on down as our principle warmth in such a wet environment (we have down sleeping bags too and a tarptent squall 2 that "mists" a little)? Should I add something like a r1 hoody (or ibex indie) or switch out the down jacket for something synthetic?
Any advice would be appreciated, Thanks
