The Domex Trailblazer 500 is a 3-season down bag. Being down fill it weighs a lot less, and packs much smaller, than most 3-season synthetic fill sleeping bags.

The body-contoured mummy shape with a box foot maximises thermal efficiency by reducing dead air space while maintaining room for natural foot movement. The ¾-length snag free zip with locking double sliders makes entry and exit easy, minimises heat loss yet allows body temperature control if needed.

The horizontal baffles maintain the even distribution of down and the adjustable neck baffle wraps around the neck and upper chest to prevent warm air escaping when you shift during the night, a feature often reserved for higher-end bags. The draft tube prevents cold spots along the zip and the contoured draw-cord hood is shaped to keep head heat loss to a minimum.

Available in Standard and XT sizes, the Trailblazer 500 suits a range of body types. The XT model adds 10 cm in length and 7 cm at the shoulder for taller or broader sleepers who need the extra room.
