Why Choose This Sleeping Bag?
Duck down outperforms synthetic fill at low temperatures — it compresses smaller, weighs less, and insulates better when dry. The JUNGLE KING bag takes that advantage and adds a mummy cut that eliminates dead air space, a draft collar that stops cold from sneaking in at the neck, and a splicing system that lets two bags become one for couples or group warmth. It’s a serious bag for serious conditions.
