Answer:

I’ve got three little words for you: Hot. Water. Bottle.

I use this technique religiously. Right before bed, boil up a liter and transfer to a leakproof bottle (I always use a plastic one like the GSI DukJug Bottle, but I imagine a metal one would work also.) Tuck it into the bottom of your bag and enjoy the beautiful warmth.

A couple other tips:

  • Make sure your pad is warm enough (an air-only mattress ain’t gonna cut it in the winter; you need something with some insulation like Big Agnes’s Insulated Air Core ), and long enough so that your feet don’t hang over the edge.
  • Wear a clean, dry pair of warm wool socks to bed. Store a pair in the foot of your bag to use just for sleeping, that way you won’t be tempted to sully them when your trail socks get wet.
  • Or get a pair of these little beauties, the Feathered Friends Down Booties (above). They have a removable outer shell, which is great for padding around camp but at bedtime, strip them off and slide your down-ensconced feet right into your bag for a big-time warmth boost. Sweet dreams! –KRISTIN
