Outwell concentrates on making products suitable for camping. The liner fabric used in this sleeping bag is brushed polyester, making it slightly heavier but also more comfortable than the smooth and slippery fabrics used in hiking-oriented alternatives. The zipper goes all the way to the second corner, making it possible to open the bag up all the way. Children's sleepingbags are not standard tested for temperature ratings. This bag is, however, made for so-called "two season" use: in addition to summer nights, it takes care of suitably warm late spring and early autumn nights. There are holders at the foot end of the sleeping bag, enabling you to fold the bag to a shorter length - great for helping avoid the kid from ending up "too deep" in the bag. - Suits users up to 140 cm - Liner: brushed polyester fabric - Isofill synthetic insulation (fill amount: 600 grams) - Compression stuff sack
