Pack For Iceland Winter Carry-On: What 14 Days in Iceland Taught Me About Carry-Only Winter Packing

Most people think you need a checked bag for a two-week winter trip to Iceland. They’re wrong. I spent 14 days there in February with a single 40L carry-on backpack and a small daypack. No checked luggage. No regrets. Here’s exactly how I did it—and what you should leave behind.

The Layer System Is Non-Negotiable

Iceland in winter is a game of microclimates. One hour you’re in a blizzard at Seljalandsfoss. The next you’re sweating inside a geothermal café. The only way to handle this is a three-layer system that you can add or remove in 30 seconds.

Base Layer: Merino Wool, Not Cotton

Cotton kills in Iceland. It gets wet from sweat or snow and stays wet. You’ll freeze. I brought two Icebreaker 200 Oasis crew tops (about $90 each). Merino wool wicks moisture, doesn’t stink after a week, and dries fast if you wash it in a sink. One to wear, one to wash. That’s it.

Mid Layer: One Insulator That Does Everything

You don’t need three fleeces. You need one good mid-layer. I used a Patagonia Nano Puff hoody ($279). It’s synthetic, so it still insulates when damp, and it packs down to the size of a cantaloupe. For colder days (below -5°C), I added a Uniqlo Heattech Ultra Warm crew underneath the Icebreaker. That combo handled -12°C at Jökulsárlón with no issues.

Shell: Waterproof, Windproof, Breathable

Icelandic wind laughs at cheap rain jackets. I wore an Arc’teryx Beta AR ($650). Overpriced? Yes. But after watching tourists in flimsy ponchos get soaked and miserable at Skógafoss, I stopped questioning the cost. Must-haves: pit zips for venting, a helmet-compatible hood (you’ll wear it over a beanie), and sealed seams. If you’re on a budget, the Outdoor Research Foray ($225) is the next best thing.

The Footwear Decision That Will Make or Break Your Trip

I see people in Uggs at the Blue Lagoon and want to scream. You need waterproof boots with good traction. I brought one pair: the Merrell Moab 3 Mid Waterproof ($145). They’re light enough for walking around Reykjavík but sturdy enough for glacier hikes. I wore them on the plane to save space. No second pair of shoes—just a pair of Hoka recovery slides ($60) for the hotel room.

Critical mistake: Don’t bring brand-new boots. Wear them for at least 30 miles before you go. Blisters on Day 2 of a 14-day trip will ruin everything.

For socks, three pairs of Darn Vermont midweight wool socks ($25 each). Wash one pair every three days in the sink with Dr. Bronner’s soap. They dry overnight on a radiator. That’s enough.

What Goes in the Bag: The Exact List

Here’s the full packing list I used. No filler. No “just in case” items.

Total weight: about 9kg (under the 10kg carry-on limit for Icelandair).

What You Should NOT Bring

Let’s be direct. These items will waste space and weight.

• Jeans. They absorb water, take two days to dry, and freeze solid. Leave them at home. I brought one pair of Fjällräven Vidda Pro trousers (G-1000 fabric, waxed for water resistance) and one pair of lightweight hiking pants from Kuhl. That’s enough for two weeks.
• More than one book or journal. You’ll be outside 12 hours a day. Read on your phone. I used the Kindle app on my iPhone 15 Pro and downloaded maps offline.
• Hair dryer or straightener. The air is so dry your hair will look fine in five minutes. And every hotel has one if you really need it.
• Multiple camera lenses. I shot everything with an iPhone 15 Pro and a small GoPro Hero 12 ($399). The GoPro handled spray at Gullfoss better than any DSLR would have.
• Liquid laundry detergent. Use solid shampoo bars for washing clothes. I used a bar from Ethique ($16) for both hair and sink laundry.

If you’re still tempted to pack a checked bag, ask yourself this: do you want to spend 30 minutes at baggage claim while everyone else is already in the rental car? No. You don’t.

When the System Breaks and How to Fix It

Even a perfect packing list has failure points. Here are the three that got me—and how I’d handle them next time.

Failure 1: Wet boots that don’t dry overnight. After a full day in sleet at Þingvellir, my Moab 3s were soaked through. I stuffed them with newspaper from the hotel front desk and placed them near the radiator. By morning they were 80% dry. Next time I’m bringing a pair of Sealskinz waterproof sock liners ($40) as backup.

Failure 2: Phone battery dying in -10°C. Cold kills lithium-ion batteries fast. My iPhone went from 60% to dead in 45 minutes while I was taking photos at the Northern Lights. Solution: keep the phone in an inner chest pocket against your body. And bring the Anker PowerCore 20100 ($55) in your daypack.

Failure 3: The merino shirt that didn’t dry in time. I washed my Icebreaker top one night and hung it in the bathroom. No radiator in there. It was still damp at 7 AM. I wore it anyway and was cold for the first hour. Now I always hang wet wool near a heat source—even if it means draping it over the hotel room heater.

The real lesson? Stop overthinking. Pack less than you think you need. Iceland is expensive to fly to, and baggage fees for a checked bag (about $70 each way on Icelandair) are a waste of money you could spend on a good meal in Reykjavík. One bag. Two weeks. Done.
