Sierra Designs Night Cap Sleeping Bag

Instead of a zipper, the Night Cap uses an oversized, integrated comforter that wraps around you like a blanket at home. You simply slide into the bag, and the comforter stays tucked in place to trap heat, allowing you to move freely without feeling restricted by a traditional mummy shape.

Yes, the bag features an integrated sleeve on the bottom that holds your sleeping pad securely in place. This keeps you centered on your pad all night, preventing you from rolling off onto the cold ground.

The Night Cap has an ISO Limit rating of 20°F, which is the temperature at which an average person should remain comfortable without shivering. If you tend to sleep cold, you may want to use this bag in conditions slightly above the 20°F limit.

The bag includes a patented self-sealing foot vent. You can easily stick your feet out of the bottom to regulate your temperature without having to unzip the bag or expose your upper body to the cold air.

This bag is designed for users up to 68 inches (5'8") tall. If you are taller than this, you may find the bag too short to fully cover your head and shoulders comfortably.

Yes, the SierraLoft Eco synthetic insulation is specifically chosen for its ability to retain warmth even when damp. It is a reliable choice for humid or wet environments where down insulation might struggle.
