Packing is almost equal to down sleeping bags, but Topas is hypoallergenic and does not mind water. Double-sided YKK zipper covered by a flap ensures that it does not blow, it can be closed both inside and outside and of course there is the possibility of connecting two sleeping bags with left and right zip totogether (can be connected together also with a sleeping bag Micra and Spirit). It is equipped with two loops to hang and dry. The sleeping bag has a two-layer shingle thermal insulation, that is mean the one layer is sewn to the topsheet but the second layer is cut into shingles and one side sewn to the innersheet and the second side to the topsheet. The sleeping bag is delivered in a compression bag - during storage we recommend to remove the sleeping bag from the compression bag.
