A silk sleeping liner is a valuable addition to your Camino packing list for enhancing sleep comfort and hygiene. Choose a lightweight, breathable silk liner that can easily fit inside your sleeping bag or be used on its own in warmer conditions. Silk is a natural temperature regulator, helping to keep you cool in the heat and warm in the cold. It is also hypoallergenic and gentle on the skin. Look for a liner with a compact, packable design that comes with a small storage pouch for easy carrying.
