Before we dive in, insulation doesn't create warmth, it can only trap it, retain it, and slow down created warmth's escape. That's why almost our whole list is about trapping heat.
1) Reduce Moisture
Moisture might be the number one threat to your warmth when camping, staying dry is key.
Do this by:
- Bringin a fresh change of clothes to sleep in.
Waterproof Down or Synthetic Insulation.
Vent to avoid sweat/overheating.
Breathable fabrics with a water-resistant coating.
Before you hit the hay, grab a complex carbohydrate snack this will supply the calories your body needs to continue producing heat throughout the night.
Here are a few examples:
- Energy Bar
- Cheese Stick
- Banana and Peanut Butter
- Almonds or Cashews
3) Move Around
Hit a quick set of pushups before you snuggle in. A burst of physical activity will get your blood circulating and your heart rate up. This is great for overcoming the first 5-minute shiver fest when you start the night. Don't work so hard you break a sweat though (see #1).
4) Fill the Gaps
Your body has to heat up the entire area contained by your insulation. Therefore, reduce the empty space as much as possible, that way more of your warmth will be reserved for your body - rather than being lost to the air. Try to Pre-Warm your extra clothes then stuff them inside with you to help reduce the empty space.
5) Wear Wool
We suggest a base layer set of merino wool + a wool beanie + medium wool socks. This will keep your skin covered and the wool will immediately wick any moisture away from your body. Synthetic options work well too, just avoid cotton.
