An accessory for the broader among us, the Sleeping Bag Expander is a simple, clever way of adding wiggle room to all One Planet sleeping bags. This zip-in extension can be left attached to your bag ready for the next use, and adds an extra 25 centimetres in diameter at the shoulder of all One Planet Sleeping bags. The design tapers in at the end to maintain your sleeping bag’s shape and performance.

Note: As many of our down sleeping bags are filled to order, it can often take 7 to 10 business days before they are ready to ship.

NOTE: shown here attached to sleeping bag. Sleeping bag not included.
