Same backpack, view of carrying straps, again no waistband. Note there is no frame for support – this type of frameless rucksack is essentially a carrying sack with all the weight supported by the shoulders. Colloquially known as a “kidney crusher” as that’s where it bounced when you walked or ran while carrying it. Most unsuitable for the carrying of heavy loads, and worse still when anything hard with straight edges was inside it and close to your back. Nevertheless, they were available and remained in use throughout the Winter War although by 1944 they had been largely retired.
