How to Choose a Camp Blanket for All Seasons

Quick answer

Choose a wool-blend field blanket for three-season versatility and a lightweight synthetic blanket for summer; for deep winter, opt for an insulated or heavy wool option.

Decision rules for choosing your camp blanket

• 1. Match insulation to your coldest expected temperature: If you camp mostly in summer (above 50°F / 10°C), a lightweight synthetic or thin wool blanket works. For shoulder seasons (30–50°F / -1–10°C), choose a mid-weight wool or wool-blend blanket. For winter (below 30°F / -1°C), go with a heavy wool blanket or an insulated field blanket. Check the blanket's weight and material; heavier wool (3+ lbs) handles colder temps better.
• 2. Consider the carry method: Car camping: prioritize comfort and durability—choose a wool or waxed cotton field blanket that rolls up neatly. Backpacking: prioritize weight and packability—look for a synthetic blanket that compresses small. If you do both, a medium-weight wool blanket (2.5–3 lbs) is the best compromise. A field blanket like the O.S. Field Blanket is ideal for car camping; backpackers should look for sub-2 lb synthetic options.
• 3. Evaluate weather resistance needs: If you camp in damp or windy conditions, choose a blanket with a weather resistant backing (like waxed canvas) or a waterproof shell. For dry climates, a pure wool or synthetic blanket without a backing is lighter and more breathable. Waxed cotton backed wool blankets add wind and moisture protection without adding bulk.
• 4. Decide on care and longevity: Wool requires gentle washing and air drying, but it lasts decades. Synthetics are machine-washable and dry quickly but may degrade faster under UV and abrasion. If you want a heirloom piece, invest in wool; for low-maintenance gear, choose synthetic. Wool demands more care but offers longer service life and natural odor resistance.

Product highlights
