Kelty MISTRAL 0

The Kelty Mistral 0 is a winter synthetic bag with Recycled CloudLoft ECO insulation made from 100% recycled fibers, rated by the manufacturer to -13°C comfort / -18°C limit — the warmest-rated model in this lineup. Its 9.1 warmth-to-weight ratio is also the best of the group, notable for a synthetic-fill bag without down. The baffles are sewn-through, simpler than the box-wall baffles on pricier models — meaning slightly reduced insulation at the seams, offset by a generous 1421 g fill charge. Both shell and liner are recycled 68D polyester taffeta with a PFC-free DWR finish, backed by a full draft collar, draft tube, and adjustable contoured hood. The two-way zipper runs the full length. Internal length is 193 cm, maximum user height 183 cm, and it packs to a bulkier 51 x 30 cm, consistent with its winter category. At 1984 g total, the weight is reasonable for a bag rated to -18°C. The Mistral 0 makes sense for winter trekking and expeditions where recycled materials and solid thermal performance matter more than shaving grams.
