1. you wore too much going uphill ... its that simple ... unless its pretty cold or at lower exertion i dont wear a R1 uphill ... period
2, if you DO get cold at stops ... use a light puffy to keep you warm .. you can strap it to yr pack ... or tie it like a bandolier like i do when climbing ... and use yr zippers, theyre there for a reason
3. wear the lightest base layer you can get away with and MAYBE a light shell on the way up ... this means something like one of those cheap running mesh shirts ...
4 on the way down THEN wear the R1 or light puffy unzipped if youre getting a bit cold
5. the more you sweat, the more water you need to consume, the more dehydrated you are, and the less well you think
6. which means youll also need to carry more water ...
7. if youre always overheating or running out of water in the winter ... youre doing something wrong ... and chances are its not the gear, but the use thereoff
8. technique and skill over all that fancy gear any day of the week for any trip
the best quote is
but most of my team members aren't even aware of BPL, all they do is they just hike.
which is the best advice possible ... dont worry about what people on BPL or the intrawebs are doing ... find out what works in real life, test it out, over and over again
get in the best shape you can ... the best way to lose weight or make yr pack "feel lighter" is to be in shape ...
as to the group being "azzholes" ... if you were to come climbing with me i would expect you to be in basic shape, have certain skills and be able to climb at a certain level, not that im a good climber ... but you should be more a real climber than a virtual one ;)
smart and experienced people wear as little as possible when moving ... and one reason why they dont "wait for others" is because they have to keep moving in order not to get cold ... or theyll waste time pulling out a puffy (which they may not carry) and cooling down ...
