An accessory for the broader among us, the Sleeping Bag Expansion Gusset (or 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 to the shoulder of ONE PLANET sleeping bags. (All models except the Camp Lite series.) The design tapers in towards the foot to maintain your sleeping bag’s shape and performance.
NOTE: we use YKK zips on our sleeping bags. These zips can vary up to 2% in length/stretch. The Expansion Gusset is shown attached to a sleeping bag: the sleeping bag is not included.
