Inners of all Series are constructed from V2 Vapour Vent.

All One Planet sleeping bags have an internal zippered security pocket on the upper chest area. It is the perfect size for keeping your passport, cash and other vital items out of harms way as you sleep. The pocket is also fantastic in sub-zero temperatures for keeping batteries operational, and contact lenses from freezing solid.

'D' shaped three-dimensional draft tubes block any cold breezes from penetrating the zip closure. Booster Series Bags have no draft tube and Backpacker Series bags have a single draft tube, whilst all others have dual draft tubes.

Fabric near the zip is firmly sewn-off to prevent the slider snagging.

Three-dimensional neck muff (Except Stowaway, Robbin Hoodless and Boosters) with elasticised closure, stops warm air within the bag escaping past your head.

The Winter Lite, Bush lite and Tour Lite all come with a pillowslip that simply clips into position. Fill it with spare clothing to make a pillow, and throw it into the washing machine when it gets dirty.
