Frequently Asked Questions
Should I wear cotton under my hunting clothes?
Never wear cotton when you are hunting in cold or wet conditions. Cotton absorbs moisture and stays wet, which creates a heat-sapping trap against your skin. This is a dangerous mistake that can lead to hypothermia in extreme scenarios. Always reach for synthetic or wool alternatives to stay dry and safe.
Does a base layer need to be tight?
Yes, your base layer should have a form-fitting cut to work correctly. A snug fit ensures the fabric maintains constant contact with your skin to pull sweat away. If you prefer a looser feel, you might be tempted to size up. However, doing so will decrease the thermal efficiency of the garment.
How many base layers do I need for a week-long trip?
Two sets are usually plenty for a seven-day hunt if you have the chance to rinse them. Merino wool is excellent here because it resists odors and can go multiple days without needing a wash. If you are using synthetics, you might want an extra top for comfort. Focus on packing light while prioritizing materials that do not hold onto human scent.
Can I wear a base layer as a standalone shirt?
You can, but consider the durability of the specific fabric. Many lightweight base layers are delicate and might snag easily on briars or sharp branches. If you plan to hike in just your base layer, look for a heavier weave or a model designed for outer-layer wear. Otherwise, use it exclusively as the foundation of your layering system.
How do I wash my base layers properly?
Use a scent-free detergent to ensure you do not alert game to your presence. Avoid fabric softeners, as they leave a residue that clogs the pores of the fabric and ruins its wicking performance. Air drying is always the safest method for longevity. High heat in a dryer can shrink wool or damage the elastic fibers in synthetic blends.
