Do I really need waterproof gear in summer?

Yes. Summer in Iceland means 50-60°F days with frequent rain and wind. You'll be miserable in just a sweatshirt and jeans.

Can I buy gear in Iceland instead of packing it?

You can, but it's expensive. Outdoor gear costs 30-50% more than US prices. Rent gear in Reykjavik if you don't want to buy or pack.

What if I'm only staying in Reykjavik?

You still need layers and waterproof gear. Even city walking involves wind and rain. Skip the heavy hiking boots for waterproof sneakers if staying urban.

How much should I pack for a week-long trip?

Pack 3 base layer sets, 2 mid-layers, 1 shell jacket, 1 warm jacket, and extra socks/underwear for 7 days. You can wash clothes but always have backups dry.

How to pack for Iceland's unpredictable weather

Pack in layers with waterproof outer shells, bring warm base layers even in summer, and always include waterproof hiking boots. Iceland's weather changes hourly, so you need gear that works from 40°F summer days to sudden snow squalls.

Start with moisture-wicking base layers. Pack 2-3 merino wool or synthetic base layer tops and bottoms. These work as your foundation in all seasons. Avoid cotton completely - it stays wet and cold.
Add insulating mid-layers. Bring a fleece jacket or down vest for warmth. Pack one heavy option (down jacket) and one lighter option (fleece pullover) so you can adjust to conditions.
Pack a waterproof shell jacket and pants. This is non-negotiable. Get a proper rain jacket with sealed seams and waterproof pants. Even sunny days can turn into sideways rain in 20 minutes.
Choose waterproof hiking boots. Pack boots that go above your ankle with good tread. The ground is wet, rocky, and slippery everywhere. Your feet will get soaked in regular shoes.
Pack warm accessories for all seasons. Bring a wool hat, warm gloves, and a buff or scarf even in July. Add hand warmers for winter visits. The wind makes everything feel 15 degrees colder.
Include backup dry clothes. Pack extra socks and underwear - more than you think you need. Bring a spare fleece in case your main layer gets soaked.
