The Outwell Celestial is a 2-season single sleeping bag designed for spring and summer camping, with a polycotton shell and soft cotton flannel lining that feels noticeably warmer and more comfortable than synthetic-lined bags at this price point. The recycled Isofill polyester filling (900 g) gives a comfort temperature of +9°C for women and a limit temperature of +5°C for men — well suited to Cornish campsite nights from May through September. The L-shaped 2-way zipper opens fully for ventilation on warm nights, and the auto-lock prevents accidental unzipping. At 1.9 kg with a 38 × 23 cm pack sack, it's a good-value car-camping bag that doesn't scrimp on feel. Available at our Newquay showroom — 4 Bamber House, Victoria, PL26 8LQ.
