In the scenario I could potentially have a lot with me because I'd be pulling a small sled...weight wouldn't be much of a factor. For me, I'd be well equipped simply because I like to be well equipped. It's unlikely I'd be without GPS or compass but for the sake of argument I'm assuming those have failed me (or I have)

I was assuming I'd be dressed warm in layers as I'd be stop and go walking throughout the day. Typically I'll wear the following for such a thing:

• Med weight synthetic, wicking, long johns
• Nylon wind proof pants (possibly the fleece lined kind, and waterproofed with Nikwax)
• Wool Socks
• Heavy boots with the foil lined style felt liners
• Wicking base layer of light wool or poly
• Poly shirt
• Windproof fleece jacket (waterproofed with NikWax)
• Windproof shell (covers the bum) with built in hood
• Poly glove liners
• Wool gloves or synthetic insulated mits
• Fleece head ever neck warmer
• Poly or Wool toque
• Wrap around sun glasses

I'd also be carrying at least one extra pair of glove liners, waterproof glove shells, 2 pair of extra socks (because I'll sweat...I always do), Goretex rain pants, and possibly a full change of clothes in case I get wet for some reason. I keep most of this stuff in an O.R. compression sack in my pack anyhow. It's a little heavy but nice and compact. Packed right it's easy to shed the extra weight if I don't need it all.
