A bag comprises two rigid i.e. form-stable lateral walls (1, 2) of equal shape and dimensions, which are parallel spaced apart from each other and each of them comprises a continuous circumferential edge (10, 20), as well as a flexible and in circumferential direction continuously arranged intermediate area (3), which is radially offset inwardly with respect to circumferential edges (10, 20) of said lateral walls (1, 2) and is furnished with a zip (4), which extends along the circumference of said area (3) and is arranged symmetrically with respect to a vertical axis (V) during the regular use of the bag and is furnished with attaching members (51, 52, 53, 54), which are arranged along the circumference at appropriate distance (a) apart from each other, wherein the bag further comprises a flexible strap (6), the width (T) of which is smaller than the distance between said lateral walls (1, 2) and which is furnished with attaching members (61', 62', 63', 64'; 61'', 62'', 63'', 64''), which are in appropriate manner distributed between each terminal portion (60', 60'') and a central region (60) of said strap (6). |
