Here is some background info:
On the move, I'm always REALLY hot. As in when I would run on the shore of Lake Michigan in January in 12 deg temps: off come the gloves, off comes the hat, unzip the light jacket, etc.
Static, I'm oh-so-very-cold if the temps dip into the 50s or so. Heaven forbid if there's a breeze…..
I am currently in the worst shape of my life, but I have a few months of running and strength training ahead of me so hopefully this won't be as big an issue as it is today.
Two years ago on the JMT I wore a Rail Riders adventure (read: dork) shirt and I don't remember being all that hot.
Last year on the JMT I wore a cap2 zip T, long sleeve, and was miserably hot all day long. I didn't even need a wind shirt at the passes.
I have no idea if it was actually hotter, or if I just didn't tolerate it well, or if it really was the dork shirt. I was in far worse physical shape last year than 2 years ago, and I didn't acclimate to the elevation very well throughout the trip.
I've never hiked in the rockies. we are planning on 5 weeks.
OK. Now to this year.
I plan on wearing:
Rail Riders adventure shirt
nylon running shorts with liner (i've worn running shorts for years to hike in – my favorite no matter what)
nike pro sports bra
wide-brimmed hat
atra lone-peak 2.0
coolmax short socks
DG gaiters
umbrella (trying for the first time)
Carrying:
arcteryx phase SL tights (4.3 oz)
montbell dynamo wind pants (2.6)
ZPacks rain skirt (2.0 oz)
marmot essence rain jacket (6.0 oz)
backcountry hadron pullover puffy (7.2)
cap 4 hoody (8.7 – YIKES)
ZPacks rain mitts (1.0)
rab cirrus windshirt (3.6)
black rock gear down hat (1.0)
Ran power stretch gloves (1.2) MAYBE….my hands aren't cold very often. but for early am hiking, or when the temps drop in the evening, setting up camp, etc – very nice to have
I like sleeping in the cap 4 hoody – but holy crap that's heavy. I'd rather not sleep in the RR shirt, but maybe just bring a long sleeve cap 2 or something? I'd like to have some sort of dry shirt to change into at night – yes the RR shirt dries quickly, but I do like dedicated sleeping clothes. I really don't like stopping at camp all sweaty and just put on my puffy over that. but maybe that's just what I should do??
And I'm also considering actually leaving the Rab Cirrus behind, or finding a different wind shirt. I rarely actually hike in it – I frequently overheat in wind shirts (even the hallowed pre-2012 Houdini I found uncomfortable to hike in) and really only used them for a stopping layer or for a few minutes of early morning hiking before I get warmed up. If I did that, couldn't I just use the Essence for those few minutes?? Or am I asking for trouble just to drop 4 oz??
Anyway – big questions:
stick with the dork shirt, or go all the way to a short-sleeved top (since I'll be carrying and using sunscreen anyway) to help manage my overheating-on-the-move? or stick with the cap2 zip t because last year was just weird?
cap4 hoody too much for a sleep/insulation/insurance layer? maybe just the hoodless version? something else entirely?
leave the wind shirt behind or find a different one?
any other system suggestions? I'm happy with my lower body stuff – that has worked really well for me the past few years. but oh not so sure about the rest….
Thanks!
