For years, my basic 3-season upper body setup for the Rockies/Sierras has been:
silkweight capiline (5 oz) never take it off
driclime windshirt (10 oz.) worn at rest stops, on cold days, to sleep in
micropuff pullover (11 oz), worn in camp, on rest days, to sleep in, as emergency warmth
Now, I've got a hooded, unlined windshirt, montane litespeed (5 oz), that I like for the same reasons everyone else does.
Problem is the driclime doesn't really fit in the system anymore, but the silkweight capiline and unlined windshirt isn't always warm enough, and the micropuff's too hot to hike in.
So, add a patagonia R1 vest (7 oz), or mont-bell chameece vest (5.5 oz)? A highloft vest would obviously be warmer for the same weight, but moisture transfer is an issue as I'd be hiking in it. Any advice?
Also, anyone know of a cheap alternative to the R1 vest? I'm thinking of cutting up an old expedition weight capilene shirt I have...
