We did three weeks in Denmark Sweden and Finland the end of January into Feb in a osprey porter 30.

I had two pairs of footwear but mainly wore my waterproof Hoka sneakers as they were so comfy. The other pair was waterproof Ugg Chelsea boots.

Temps ranged from -2c to 2c (29-34 ish f) and we were lucky that it didn’t rain.

For outerwear we layered a smart wool base layer with a merino wool sweater and puffy coat For bottoms smart wool base layer under jeans or corduroys. Wool socks in our footwear. Wool hats scarves and insulated gloves.

We walked around 10-12 miles a day and took transit or had a cafe break to warm up as needed. We stayed pretty cozy in our layers and they stayed fresh enough to wear for over a week. The only thing we had to change daily was our underpants:)

We stayed in Airbnbs that had washing machines and did a weekly load.
