Winter in Europe can be wet, windy, and wonderful. The difference between a magical night under the stars and a shivery mess is your sleeping bag. If you camp in the Netherlands or other damp regions, you need warmth that still performs even when moisture appears.
Temperature and fit: the foundation of real comfort
Use the EN/ISO comfort temperature as your main reference and add a 5–10 degree safety margin. If you sleep cold, add a little more. Comfort is what helps you sleep through the night, not just survive it.
Pick a shape and size that match your body. A mummy or semi-rectangular cut reduces the empty air you must heat. Too roomy wastes warmth, too tight restricts movement and crushes insulation.
Insulation and key features for damp European weather
Down offers the best warmth-to-weight, but moisture reduces its performance. Choose hydrophobic (treated) down if you expect humidity, or go synthetic for a safer bet in wet conditions. Synthetic bags insulate when damp and dry faster, which is ideal for coastal and forest camps in the Netherlands.
Features that matter in winter:
- Draft collar and draft tube to stop heat leaks at the neck and along the zipper
- Adjustable hood to seal in warmth
- Shaped footbox that keeps toes warm without compressing insulation
- Water-resistant shell panels in high-exposure areas like the foot and hood
- Full-length zipper with pullers that are easy to grab with gloves
Weight, packing, and care to make your bag last
For hiking or bikepacking, every gram and liter count. Choose a bag that includes a compression sack for the trail and a large storage sack for home. Never store your sleeping bag compressed. Use a liner to keep it cleaner and reduce wash cycles. Air it out each morning, keep it dry inside a waterproof dry bag when moving, and store it loosely between trips.
