What to Consider When Buying Long Johns for Men

When selecting the best long johns for men, there are several key factors to keep in mind:

Fabric Type:
Look for moisture-wicking materials like polyester or merino wool. Cotton, while soft, tends to retain moisture and may not be ideal for intense cold or activity.

Fit:
Long johns should fit snugly but not too tightly. Compression models are great for active use, while looser fits are best for lounging or layering.

Weight:
Lightweight layers are suitable for mild cold or indoor use, while heavyweight thermals are best for extreme conditions.

Durability:
Reinforced seams, anti-odor treatments, and machine-washable fabrics are all signs of a quality product that will last through many seasons.
