kelty KUSH 30

The Kelty Kush 30 is the heaviest bag in this lineup — a rectangular model with CloudLoft synthetic insulation weighing 2000 g with 1220 g of fill, and a manufacturer limit rating of -1°C. Its warmth-to-weight ratio of 0.5 is the lowest in the group, which fits the concept: this is a comfort-camping bag, not trekking gear. The soft 75D polyester pongee shell with a pintuck finish and the 50D polyester pongee liner give it more of a blanket feel than a technical one — fittingly, the maker markets it for 3-in-1 use as a bag, blanket, or pillow. There's no water-resistance treatment, but it does include an internal pocket and stuff sack. Internal length is 183 cm, shoulder width 79 cm, and maximum user height 182 cm. The Kush 30 makes sense for car camping, cabin use, or as a multi-purpose blanket at home — but its weight and lack of technical features like a hood or draft collar rule it out for lightweight trekking.
