Troubleshooting

The sleeping bag feels cold.

Ensure the bag is fully lofted, and you are using a sleeping pad with an appropriate R-value. Check that the hood is adjusted properly to minimize heat loss.

The zipper is snagging.

Carefully unzip the zipper and check for obstructions. Avoid pulling the fabric too quickly. Consider applying a zipper lubricant.

The down is clumping.

Gently massage the down to redistribute it. Make sure the bag is stored properly uncompressed. Wash and dry the bag according to the care instructions to restore loft.

The bag has a persistent odor.

Air the sleeping bag out in a well-ventilated area. If the odor persists, consider washing the bag according to the care instructions.
