I know this is an oft discussed topic and I apoligse for any repitition. I have already serached the OM forum history but haven't found the specific answers I'm after.
I'm trying to decide upon my sleeping system for a trip to Aconcagua and Chimborazo for Jan 2013. I will almost certainly be taking an exped matt and likely to be the Exped DownMat 9.
The bags I'm considering are as follows:
Make Model Weight Fill Weight Fill Power Down Grade Stated Temp © Length Shoulders (cm) Feet (cm) Price £
PHD Hispar 600 1010
900 EU
-21
80 49 525 PHD Hispar combi 800
900 EU
-6
443 Alpkit PipeDream 800 1270 800 750 EU 95/5 -17 210 70 50
Cumulus (UK) Prime 700 1235 700 870 US 96/4 -18 225 80 52 300 Cumulus (Polish) Teneqa 700 1170 700 850 EU 96/4 -17 225 85 55 220 Cumulus (Polish)
Teneqa 850 1330 850 850 EU 96/4 -24 225 85 55 245
I've ruled out Western Mountaineering, Feathered Friends and Valendre for reasons of cost and/or appropriate product. I figure that if I end up spenpding a large amount (over £400) I would rather have the PHD Hispar 600 as PHD are local and I like their kit.
Does anybody have any experience of any of the above and is there anther bag that I have missed? Does anybody know the length of the regular Hispars? They only list what height person will fit in them.
The Modular Option
Also, I am considering taking my Arc Specialist (good to 0c) and Quantum 450 (good to -10c) to put one inside the other. This won't be the lightest option (approx 1400g total) but is the cheapest as I already own them! It is along the lines of the PHD combi idea, which makes rather surprising claims (though I trust them) about the effect on the Combi TOT.
It would give me obvious flexibility, which would be good given that Aconcagua will be the coldest place I go and only 4 or so nights of that would be spent at really high altitude. I would/could combine it with sleeping in the the PHD Minimus Down Trousers and down booties, plus my down jacket (a Yukon) if really needed.
What do people think and has anybody done anything similar for Aconcagua or an other similar height/conditions mountain?
Thanks for your help.
