I know it's no record by far but for me it's a new low in this system!
Warbonnet Winter Mamba on top, Winter Yeti below.
CCF pad in the foot box reaching to behind the knees.
Wore smartwool tights, Marmot Driclime shirt, Nunatak balaclava, and down socks.
No hammock sock, no burrito, no undershield, no tarp, no beaks. Left the netting unzipped; these omissions weren't by design, I was just worn out and didn't take the time to put any of them on.
Thought I'd edit and give some weights so those new might get an idea of potential winter camping loads
5 pounds 4 ounces:
Warbonnet Blackbird 1.1 double bottom
Winter Yeti with liner
Add a McCat Ultra spinnUL and 2 TQ/ZQ GrizzBeaks 7lb 1 ounce
Add a cook kit:
MLD Caldera Cone/alcohol stove/pot
Long handled Ti spoon
MSR coffee filter
2 x 4oz Tinny bottles with Heet
Snow Peak single wall coffee cup
Black Diamond Orbit with lithium batteries
and add a CCF Pad for the sleep system 8lb 9 ounce
Add some camp clothes
Nunatak down pants
WM Flash Jacket
Add MLD Gaiters
Sierra Designs Ion Jacket (wind/rain)
Throw in a headlamp and some Aqua-Mira
And put it all in a Gossamer Gear Mariposa------13 pounds 9 ounces
Since this is for winter trekking add
Kahtoola Lightweight Campons
and a stainless steel Nalgene, for both you're adding 1 pound 14 ounces.
The lightweigt crampons are far beyond Microspikes and that extra
fuel bottle is for heating the Nalgene up before sleep.
Anyway had some time to kill and the scale was handy.
