The Kelty Dualist 0 Degrees F’s technical features are impressive yet its price is very low for the temperature rating. You are getting a -18 deg C (= 0 deg F, as per the name) comfort temperature rating. The bag features ThermaDry, which is a mix of DriDown and ThermaPro insulation. DriDown is a 600 fill power down that has a hydrophobic finish so that it stays dry 10 times longer than untreated down, which in turn allows it to retain 2.7 times more ‘loft’ (fluff) and dries 33 per cent faster than untreated down. ThermaPro is a synthetic insulation; together with DriDown it forms two separate layers – and this combo is said to be 20 per cent lighter and 40 per cent more compressible than a bag made from just the synthetic fill. The Kelty Dualist 0 Degrees F also features a full-length side zip with a good anti-snag strip and a baffle, while a shoulder baffle traps the warm air inside the bag.
Comfort temperature rating -18 deg C
Packed size 25x30cm
NB Temperature rating is based on using the bag fully fastened with the hood up, with a sleeping mat underneath.
The Kelty Dualist 0 Degrees F was the best choice in our test if you are after a budget winter sleeping bag.
