How to Choose
When selecting long johns, consider the primary activity and climate you’ll be in. Merino wool is excellent for odor control and natural insulation, ideal for multi-day outdoor use, but it can be pricier and less durable. Synthetic fabrics like polyester blends dry faster and are often more affordable, making them better for high-intensity activities. Weight matters: lightweight is best for layering and mild cold; midweight and heavyweight provide more warmth but can bulk up. Fit is crucial—look for stretchy, flat-seamed designs that prevent chafing and fit snugly under outerwear. Finally, features like odor resistance, moisture-wicking, and durability should align with your use case, whether it’s casual wear, outdoor sports, or work.

How do I care for merino wool long johns? Wash them in cold water on a gentle cycle or by hand, and air dry to prevent shrinking and maintain softness.
Do long johns help with moisture management? Yes, quality long johns wick sweat away from the skin to keep you dry and warm, which is critical for comfort in cold weather.
Can long johns be worn in summer? Typically no, as they provide insulation and can cause overheating; however, lightweight versions may be used for protection against sun or bugs in some cases.
