I am looking for a lightweight jacket, so I will look at the options you list... while I am not doing full winter BP at this point, most of the trips are in CO, spring/fall, NM (north), AZ (mountains- winter), UT (winter)... so it tends to be higher elevations and always a chance of snow... sometimes I laugh when I read a lot of these lists... it is nice to see someone with a list that does not look like it was developed for the Sahara... :)
While I do not have the lightest pack -- a few ideas...
There is a Thermarest Pillow that is made of foam cubes... it is a square shape, multiple sizes, it is 9.2 oz. Not that light, but may be an option, it is the only "real" pillow I have used though I do not take it every time due to the weight. http://www.thermarest.com/product_detail.aspx?pID=93&cID=4
I have the medium...
I have used the Whisper Lite Intl for years... I picked up a Simmer Lite (8.1oz stove/pump) a few years back and have been using that, it uses the same pump, but is lighter then the intl. maybe 3.5 oz less? I got it at a super sale, and got it to allow better flame control- which is why I got it, since I cook cakes and stuff... it also has a better hose to the fuel bottle. Anyway, keep an eye out for one, may cut the weight a tiny bit!
Thanks for the CO Gear list!
