Be prepared for anything unexpected with our range of Ascent™ expandable sleeping bags! With a perfect weight/comfort ratio, sleeping bags from the Ascent™ range are more spacious than traditional mummy sleeping bags, while still providing the necessary thermal protection beyond the tree line. The zipper located on the right half of the bag offers great freedom of movement for the arms as well as better ventilation and allows the upper third of the sleeping bag to be converted into a mini quilt. The double-slider zipper along the entire left length of the bag and that at the feet allow the bag to be transformed into a quilt when the temperature is higher than expected. If, on the other hand, you want to be warm, simply close all the zippers and pull the drawstrings to tighten everything up and relax in complete comfort. Generous fill with high-quality 750+ Loft down provides excellent insulation, while oversized pads prevent your body heat from escaping.
