My dream jacket would keep me warm(I run cold) on multi-pitch climbs in 45-65F weather. I am hoping to wear fewer layers for climbing comfort/performance. Ideally, one jacket that I can wear over OR echo light shirt on warmer days, and over merino wool or NF futurefleec LT on colder days.
My main goal is to have one jacket that I can leave on all day through the stop/go activity of climbing.
I just got a Mountain Equipment Kinesis Jacket but haven’t tested it in the field yet. I only have 7 days to return it.
I am considering Patagonia Nano-air light, Arcteryx proton FL, Mountain Equipment Kinesis, OR Uberlayer, or any other items you guys suggest :)
