When choosing clothing for the Yukon Arctic Ultra, experience from races in winter mountains and competitions was on Greenland ice sheet and against South Pole good to have in your luggage. An important element for me is to consult with people who have local knowledge and expedition experience from corresponding areas.
Of lingerie I chose to have two layers of synthetic netting construction on both the upper body and the legs.

Wool is very comfortable to wear on body with low activity and rest, but sucks up to 90% moisture. At high activity one sweats, and then synthetic is most practical. Synthetic polycolon only sucks 6% and transports moisture from "damp air" and sweat away from the body.

As an intermediate layer I had another layer of netting, but with arms where the mesh construction was covered with merino wool. The arms are extra prone to cold and especially when using spikes.
This layer-on-layer strategy with synthetic netting on the upper body and legs is amazing. These are thin and light layers that keep you moving and balance your body temperature more easily.

Competition clothing

When the competition started, I used as an outerwear a windproof softshell jacket with a hood that has good ventilation through the breast pockets and under the arms. In addition, I had a thin and breathable, moisture transporting running jacket in synthetic insulation which I switched on or in combination with softshell jacket. At night I used to wear a down jacket on the outside. Dunvest was used rather than jacket to keep movement in the arms.
On my legs I chose one ski zip with zipper on the pages. The zipper is convenient when I get it on and off without having to take off my footwear, as well as perfect for ventilation when I get hot. When it blew bad, I used a thin one shell pant.


In competition, I chose socks from Inov-8 of merino wool and a pair of spacious Altra Lone Peak 3.0 Mid shoes. With gamblers from Gore on the outside this worked well.


On my hands I had two pairs of innervotter and a couple with large wind turbines.
The inner wards were of fleece and a pair "Liners" of wool with mesh. The Witnesses worked well individually or in combination with each other in two and three teams. PS. Gloves do not work at these temperatures!


I had an "Oluf" lining with fleece inside, good flap over the ears and zipper for airing on top. I used too one to two teams off thin baleclava with ventilation panels in front of ears and mouth. I had to fold the baleclava away from the mouth as condensation from the mouth immediately froze it firmly in the face. In my face I used blue tape in exposed areas like nose and cheekbones.

Clothing for rest and food

Every time we had food and drink break, I was quick to get on a hot one good down jacket with big inner pockets and a good hood. When we hit camp for the night I took on a synthetic hot pants with longitudinal zipper and thick socks with a pair of down shoes (bivouac shoes) on the legs.
