Just curious what y'all are carrying for clothing and sleep systems, and what kinds of winter environments you are dealing with for those systems. Please spec the # of days you are out with the intended list as well. Most interested in how/if you integrate soft shells into your system, seeing down vs. synthetic insulations, and bivy sack/tarp/tent use.
I had a recent overnighter on a ridge exposed to 20 mph winds but built up a snow wall around to shield my bivy site some. Snowing, low temps to 6-8 degrees F, high temps while on the ridge 16-18 deg F, humidity about 85%, elevation 9500, above the treeline. Here's what I took:
- ID South Col eVENT Bivy - 19 oz
- Nunatak Expedition Arc Alpinist (microlight shell, 0.85 lining, 3" loft) - 21 oz
- Zotte Foams 5mm x 20" x 60" pad (with pack under knees and feet) - 5 oz
- TorsoLite pad - 10 oz
- Rab Vapor Trail Smock (worn all the time) - 14 oz
- Integral Designs eVENT Jacket (worn on ridge traverse) - 10 oz
- Rab Quantum Endurance Parka (worn at rests/in camp/sleeping, during the day on long level sections or downhills where I wasn't creating too much heat, and late in the day as the sun went down while still hiking along the ridge) - 22 oz
Clothing on Legs:
- Arc'Teryx Gamma MX Pants (worn all the time) - 19 oz
- Cocoon pants prototype (stay tuned, going to production in 3 wks!) (worn in camp/sleeping) - 9 oz
- Mt Hardwear Hammer Gloves - 6 oz
- (prototype) Featherlite Vapor Mitts - 4 oz (available at BPL in < 1 wk)
- OR WindPro Balaclava - 2 oz
- smartwool liner socks - 2 oz
- RBH Designs Vapor Barrier Socks - 3 oz
- Intuition Liners / Dynafit MLT4 Boots - 4 lb 12 oz
Conclusions: was a little nippy in the torso and legs unless I was moving pretty quick OR was wearing the down parka while moving, which was actually pretty nice - remember - while on the ridge we had steady winds of 15-25 mph so it was really cold up there. I even added the mitts here and there during the day quite a bit.
What I'd change: maybe add a fleece vest and some very light wind pants for that touch of extra warmth in the wind.
