I plan to buy a ruck mainly for the purpose of loading it with small sandbags and increasing the weight over time. I know many have experience in this sort of thing through military training. I have not previously exercised in this manner and do not presently own a bag that is well suited to this. I am looking for a bag as well as advice on structuring a rucking program. I plan to stick with walking rather than running. I have been looking at some bags. $250 is an upper limit though I'd prefer to find something good that is significantly cheaper. I am figuring that good adjustability and padding as well as waist and sternum straps would be important for this type of use. I am figuring 40 to 50 lbs would probably be the limit on the amount of weight I would want to put in the bag. Some bags I have been considering and researching. Brute Force BR-2 5.11 Tactical Rush 24 5.11 Tactical Rush 12 TAD Litespeed Fastpack TAD Fastpack EDC Maybe something by Maxpedition or Tactical Tailor but not sure what might fit the bill. The Goruck bags look very nice but also lack a waist strap and are very expensive. The Brute Force bag looks very similar, is cheaper, and includes a waist strap. Any thoughts? Thanks.
