  • Bike shorts


  • Warm wool hat that covers your ears (training beanie)

  • Liner gloves (training gloves)
  • Poagies or mittens


  • Merino wool socks (PhD® Ski Medium for extra warmth)
  • Vapor barrier
  • Shoes one size larger
  • Winter cycling boots: make sure they're waterproof and have enough insulation for the temperatures you'll be in

  • Liquid gas stoves are best for winter
  • Titanium cookware is strong and light
  • Fuel bottle with white gas
  • 1 liter pot, cup, spoon
  • Matches, lighter, fire starter kit


  • Keep your hydration bladder under your jacket and blow back into the hose after drinking
  • Adding drink mix to your hydration bladder will make water freeze faster
  • Another option: 2 one liter bottles with bottle insulator work well, but be prepared to stop to drink
  • Small liter or half liter thermos for hot chocolate, tea, coffee or soup is a treat

Snacks & Meals:

  • High fat snacks like cheese, nuts, chocolate, sausages
  • Snacks with a high water content freeze solid
  • Smoked salmon is a great snack
  • Add butter to meals (dehydrated butter is available and adds needed calories)

Helpful Tips:

  • Test your snacks in the freezer which runs at -20F.
  • Know how to build a fire. Carry a fire starter kit. Cotton balls with Vaseline or Fritos work well.
  • Know where your lighter/fire starter is. Keep you lighter warm and in a pocket.
  • Figure out what combination works best for your hands and feet.
  • Know your stove! Practice in your yard. Maintain your stove. Carry a repair kit.
  • Carry a communication device, cell phone (make sure your battery lasts, keep it in airplane mode, carry battery charger) or carry a Spot device/satellite phone.
  • Keep your smartphone off and close to your body, unless you need it.
  • Be organized. Know where important things are in your kit: first aid kit, spare batteries…
  • Learn how to adjust your tire pressure to trail and snow conditions. Soft trails = soft tires, hard trails = hard tires. Carry a high volume pump.

Our Favorites for Fat Biking

Layering for cold weather is key to staying comfortable. Merino wool next to skin provides superior temperature and moisture regulation. To maximize the benefits of Merino wool, start with a wool base layer. Add some extra warmth with a SmartLoft vest or jacket. Keep feet happy with PhD® Ski socks that offer the benefits of Merino wool in a high-performance fit. Rounding things out, Merino wool accessories like hats, neck gaiters and gloves help provide comfort and protection from the elements.
